If you look at the bottom right connector of the diagram above, we can see an extension HAT for the 100-pin docking port will be offered, as well as an IO board, both of which should be compatible with Raspberry Pi HATs with 40-pin connectors. But so far, I could not find details about the extension HAT, nor the IO board.

The UP core is coming soon to Kickstarter with price starting at 69 Euros with 1GB RAM, 16GB eMMC flash, and WiFi and Bluetooth. Other part of the documentation show a $89 price for the 1GB/16GB board, so maybe it’s the expected retail price out of the crowdfunding campaign. You’ll find a few more information on UP Core page, but we’ll probably have to wait for the Kickstarter campaign to launch to get the full details, especially with regards to add-on boards, and pricing for various options.

Thanks to Freire for the tip.

MINIX NEO U9-H Media Hub Review – Part 2: Android 6.0 Firmware & Kodi 17

March 1st, 2017 24 comments

MINIX NEO U9-H is the successor of MINIX NEO U1 media hub with an upgrade from four to eight cores with Amlogic S912 processor, as well as added support for VP9 and HDR. The company sent me a sample, and I’ve already checked out NEO U9-H hardware in the fist part of the review, so I’ll report by testing results in Android 6.0 and Kodi 17 in the second part. Since the user interface & many of the features have not changed, I’ll refer to MINIX NEO U1 review from time to time.

Click to Enlarge

First Boot, OTA Firmware, Settings and First Impressions

I connected the MINIX A3 air mouse RF to one of the USB port, a USB 3.0 hard drive to another, and a USB hub to the last one with Tronsmart Mars G01 gamepad, a USB keyboard to take screenshots for the review, and a USB webcam. There’s also micro USB port, which you could use with the provided USB OTG adapter, but I have not used it. Last I also added USB powered speakers to the USB hub, and connected them to the 3.5mm audio jack. I also connected HDMI and optical audio cable to Onky TX-NR636 AV receiver, and an Ethernet cable to a Gigabit Ethernet swtich. Finally, I added the provided 5V/3A power supply, and pressed the power button on to start it all up. A typical boot takes around 30 seconds, and the first time, you’ll be asked to select between MINIX METRO or Launcher3 “Homes”.

I prefer MINIX METRO (below) as it’s more suited to larger screens, especially when you sit several meters from the TV. It’s the same launcher which I already described in MINIX NEO U1, except possibly for the weather indicator in the time/date window, and the mass storage devices ‘ Label is shown on the top right corner. I’d wish the WiFi, Ethernet, Bluetooth,and VPN icons on the top left were clickable, but they are not.

Click for Original Size

Launcher3 is basically the launcher you’d get with stock Android plus MINIX background image. You’ll also notice the larger mouse pointer which makes it convenient to use several meters away.

Click for Original Size

The box comes with some pre-installed apps like ES File Explorer, Kodi, YouTube, Google Play, AirDroid, MINIX Power Menu & System update apps, YouTube, Skype,  and so on.

MINIX has supported OTA firmware updates in all of their devices, so I tried with System Update app, but I could not test it there was no update to MHC16G20170216 firmware at the time.If you want to get an idea of how long you may expect to get firmware update, you can look at the forum for older products such as MINIX NEO X8-H. Eleven firmware updates have been released with the first “stock” firmware released on November, 2014 and the last (FW011) firmware released in January 2017, so it has been supported for over 2 years so far.

The Settings app is the same as with other Amlogic devices, and similar to MINIX NEO U1, so I’ll focuses on different and/or specific features.

Click to Enlarge

Once you enter the Display menu, you’ll find some typical features as well as  “Force RGB output” which may solve color / pink screen issues with some older TV, and HDR specific to Amlogic S905X/S912 processor.

If you enter the Audio settings, you’ll get options to select PCM, HDMI or SPDIF audio (pass-through), as usual, but there’s  also the Device Manager menu to select audio input and output devices.

In my setup I had three input device to choose from: on-board Mic input (3.5mm mic jack), USB-Audio – SAGE AiR Mouse (MINIX A3), and USB-Audio – Venus USB 2.0 camera, which will be important for voice commands, and video conferencing.

The output devices selection will be less useful for most people, as you can only select Auto or HDMI, as 3.5mm audio jack and S/PDIF are all outputted at the same time, and, only USB devices such as a USB sound card will show up.

You also have the same HDMI CEC, Playback settings and power key definition (standby or power off) as in MINIX NEO U1. There are three options for HDMI self-adaptation (automatic frame rate switching):

  • OFF – no processing
  • Level 1 – 23.976fps videos are processed under 1080p60Hz mode;
  • Level 2 – Switching TV’s output according to source video fps

If you go to Advanced Settings you’ll reach Android Marshmallow settings, and the main difference compared to competing Amlogic TV box, but already present on MINIX NEO U1 are “MCU settings” where you can enable autostart (no need to press power button), RTC alarm, and upgrade the MCU firmware.If we go into the Storage & USB section, we’ll find out a 10.89GB partition is available to the user, with about 1 GB used.

The system could also mount both NTFS and exFAT partitions, but not EXT-4.

If we go into About MediaBox, we’ll see the model number is indeed NEO-U9-H, and that it runs Android 6.01 on top of Linux 3.14.29 with the Android security patch dated on August 1st, 2016. The firmware is not rooted, but if that’s something you need I’m pretty sure a method will show on the forums in due time, although I’d prefer a switch in Android option to root and unroot the box as needed.

I shortly testing MINIX IR remote control and it worked at least for up to 10 meters. However, I really recommend getting MINIX A3, or if you don’t need voice input, MINIX A2 Lite air mouse, as it makes a big difference when using various Android apps. If you already own a box with MINIX A2 Lite air mouse, don’t worry that it will interface with MINIX A3 and control two devices at the same time, as my A2 Lite would not work with my A3 USB dongle. Voice input works fine as tested with Voice Search app. Press the microphone key on the remote to enable it, and you can now use “OK Google”, as you’d do on your smartphone. Just make sure Audio device input is set to the remote control. If you want to turn off the microphone, simply press the microphone key on the remote control. MINIX NEO A2 worked well up to 10 to 12 meters, and I could even see the mouse cursor at that distance.

I could install all apps I needed through Google Play, and the free version of Riptide GP2 via Amazon Underground. However, when I tried the free version of Riptide GP: Renegade it to “update your Amazon App to Amazon Underground to start experiencing actually free”. I had already isntall it, but clicked on Update Now anyway, and after update I had the exact same error message.

That’s probably an issue with Amazon itself than with the box.

Power handling appears to be implemented exactly the same way as MINIX NEO U1, so you can go into standby, reboot, or power off the device with the remote control, or the power button. You can also power the device back on using either the IR remote control or MINIX A3 air mouse.

Power consumption is also similar to the previous model, as measured with or without hard drive using a power meter:

  • Power off – 0.1 Watt
  • Standby – 0.4 to 1.1 Watts (most of the time on 0.4)
  • Idle – 3.0 Watts
  • Power off + USB HDD – 0.1 Watt
  • Standby + USB HDD – 1.2 Watts with the HDD LED off. Be patient it may take about one minute to reach this power level with a hard drive connected.
  • Idle + USB HDD – 5.0~5.4 Watts

As expected, MINIX NEO U9-H dissipate power well thanks to its large heatsink. I measured 36°C and 37°C respectively on the top and bottom of the case after Antutu 6.0, and the temperature went up to 44°C and 49°C after playing a 2-hour 1080p H.264 video in Kodi, and 47°C and 54°C after playing and Beach Buggy Racing & Riptide GP2 for around 30 minutes. I quickly went to CPU-Z after exiting the game, and found the CPU temperature was 71°C.

So my first experience with MINIX NEO U9-H was even better than the very good one I had with MINIX NEO U1, since some of the bugs found the first firmware for the previous model, e.g. device stuck in standby mode, video output falling back from 4K @ 60 Hz to 1080p60 from time to time…, could not be reproduced with the new model.

Video & Audio Playback with Kodi 17.1-RC1, DRM Info

MINIX recommends the use of their XBMC MINIX Edition fork of Kodi for MINIX NEO U1, but with their new model, the company told me Kodi 17 worked well in U9-H, so I just use the pre-installed version: Kodi 17.1-RC1.

Click to Enlarge

I’m tested various video container formats, and video/audio codec playing files from a SAMBA share via (Gigabit Ethernet), unless otherwise noted.

Linaro media samples and some Elecard H.265 samples could also play fine except for VP8 1080p sample:

  • H.264 codec / MP4 container (Big Buck Bunny) – 480p/720p/1080p – OK
  • MPEG2 codec / MPG container –  480p/720p/1080p – OK
  • MPEG4 codec, AVI container 480p/720p/1080p – OK
  • VC1 codec (WMV) – 1080p – 480p/720p/1080p – OK
  • Real Media (RMVB), 720p / 5Mbps – OK
  • WebM / VP8 480p/720p – OK; 1080p: Not perfectly smooth (Note: software decode)
  • H.265 codec / MPEG TS container  – OK

I also enabled automatic frame rate switching in Kodi and Android settings (HDMI Self-adaption level 3), and it worked very well, which I think is a first amond the 8 or 9 Amlogic S912 I’ve tested so far.

Next up are some videos with various bit rates:

  • ED_HD.avi – Not smooth at all
  • big_buck_bunny_1080p_surround.avi (1080p H.264 – 12 Mbps) – First time: image freezes after a few seconds; second try: OK
  • h264_1080p_hp_4.1_40mbps_birds.mkv (40 Mbps) – OK
  • hddvd_demo_17.5Mbps_1080p_VC1.mkv (17.5Mbps) – Not perfectly smooth
  • Jellyfish-120-Mbps.mkv (120 Mbps video without audio) – OK

So the Jellyfish video plays better than in MINIX NEO U1 (Amlogic S905), but some other problems have showed up with other videos.

I’ve then checked out audio capabilties of the TV box with PCM (stereo) output, as well as HDMI and S/PDIF pass-through in Kodi. I also tested PCM (downmix) with MX Player to make sure those DTS and Dolby licenses are indeed valid for any apps. I could configure Kodi to pass-through AC3, E-AC3, DTS, TrueHD, and DTS-HD.

Click to Enlarge

MINIX NEO U1 did not support DTS-HD when it launched in December 2015 (firmware updates have fixed that), but MINIX NEO U9-H passed most tests just fine.

Video PCM 2.0 Output
(Kodi)
PCM 2.0 Output

AC3 / Dolby Digital 5.1 OK OK OK (Dolby D 5.1) OK (Dolby D 5.1)
E-AC-3 / Dolby Digital+ 5.1 OK OK OK (Dolby D 5.1) OK (Dolby D 5.1)
Dolby Digital+ 7.1 OK OK OK (Dolby D+ 7.1) OK (Dolby D+ 7.1)
TrueHD 5.1 OK No audio OK (TrueHD 5.1) Audio Formats Not Supported over S/PDIF, and will show as PCM 2.0 or Dolby D 5.1 depending on whether AC3 transcoding is enabled in Kodi
TrueHD 7.1 OK No audio OK (TrueHD 7.1)
Dolby Atmos 7.1 OK Switch to AC3 audio track (beep), as TrueHD is not supported TrueHD 7.1*
DTS HD Master OK OK OK (DTS-HD Master) OK (DTS 5.1)
DTS HD High Resolution OK OK OK (DTS-HD HR) OK (DTS 5.1)
DTS:X OK OK DTS-HD Master* OK (DTS 5.1)

* My AV receiver (Onkyo TX-NR636) does not support Atmos nor DTS:X, so the fallback to respectively TrueHD and DTS HD Master is normal. So overall HDMI and optical S/PDIF pass-through is working well with my test samples, downmixing from Dolby Digital and DTS to stereo audio works, and the only problem is the lack of downmixing of Dolby TrueHD / Atmos audio in video apps that respect Dolby & DTS licenses.

4K video can now be played pretty well in Kodi, almost as well as with MX Player:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 – OK
  • sintel-2010-4k.mkv – OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265) – OK
  • MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC, 24 fps) – Not smooth at all, and the problem gets worse when automatic frame rate switching is enabled.
  • phfx_4KHD_VP9TestFootage.webm (VP9) – OK
  • BT.2020.20140602.ts (Rec.2020 compliant video) – OK, but it played for about 2 seconds, then buffered for a few more seconds before resuming playback normally
  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • big_buck_bunny_4k_H264_60fps.mp4 – The video plays in slow motion (4K H.264 @ 60 fps is not supported by S912 VPU)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) – OK
  • 暗流涌动-4K.mp4 (10-bit H.264; 120 Mbps) – Plays at around 2 fps (as expected since it uses software decode as S912 does not support 10-bit H.264)
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – USB hard drive playback: Not smooth
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – OK
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Plays, but not always perfectly smooth as with all Amlogic S912 TV boxes.

It’s all good, except for one 10-bit H.265 video that won’t play smoothly at all. Other problems are related to limitation of Amlogic S912 processor like the lack of support for 10-bit H.264, and 4K H.264 is limited to 30 fps, and very high bitrate videos (~240 Mbps) cannot be played smoothly.

Sintel and AMAT ISO blu-ray files and 1080i MPEG videos could play just fine. Lower resolution Hi10p (10-bit H.264) could play, but 1080p was not that smooth:

  • Commie] Steins;Gate – NCED [BD 720p AAC] [10bit] [C706859E].mkv – OK for video, audio and subtitles
  • [1080p][16_REF_L5.1][mp3_2.0]Suzumiya Haruhi no Shoushitsu BD OP.mkv – OK for audio and susbtitles, but the video was not smooth

While my TV (LG 42UB820T) does not support 3D, but I played some stereoscopic 3D videos to find out if they could be decode:

  • bbb_sunflower_1080p_60fps_stereo_abl.mp4 (1080p Over/Under) – OK
  • bbb_sunflower_2160p_60fps_stereo_abl.mp4 (2160p Over/Under) – Stays in UI
  • Turbo_Film-DreamWorks_trailer_VO_3D.mp4 (1080p SBS) – OK

Some movies fron my library with various container/codec combination such as VOB, IFO, MKV, AVI, MP4 and MKV could all play just fine. However, I noticed some micro audio cuts in some videos with AC3 and HDMI audio pass-through enabled. I could not reproduce the issue with all videos, and using optical S/PDIF instead of HDMI solved the issue. Finally, I could play a complete 2-hour video. You’ll be all sample mentioned above here.

I’ve decided not to report Antutu Video Tester in my reviews, since Antutu appears to have stopped development, and the app has been removed from Google Play.

DRM Info results are however quite interesting.

Click to Enlarge

MINIX NEO U9-H supports both Widevine K1 and Microsoft Playready DRM, which means you could get full HD and 4K UHD resolution for some premium apps. However, it is not a certified Netflix device, so if you install Netflix app from Google Play, you’d still be limited to standard definition. However, as previously reported, you should be able to install a Netflix apk that allows HD resolution for any Widevine L1 capable device. I don’t have a Netflix account, so I have not tested myself. YouTube is working fine up to 1080p.

Network Performance (Wi-Fi and Ethernet)

I’ve transfered a 278MB file between a network share (SAMBA) and the internal flash for three times using ES File Explorer, and averaged the results in order to evaluate WiFi performance, testing both 802.11ac and [email protected] GHz. Results are sadly underwhelming. [Update: WiFI performance is OK, but WiFi + SAMBA performance suffers. That’s likely an Amlogic Android SDK issue. See comments]

Throughput in MB/s – Click to Enlarge

I’ve highlighted both MINIX NEO U1 and NEO U9-H results in the chart above as they make use of the same Ampak module for WiFi, but I got much different results, despite the same testing conditions.

802.11ac performance was 2.3 MB/s on average, and 802.11n achieved 1.5 MB/s both of which are below average, but consistent with the performance I got with other Amlogic S912 devices.  The chart however makes it worse than it really is, because download speed was 5.6 MB/s for 802.11ac, and 2.1 MB/s for 802.11n, with upload transfer rate being much lower, and causing the average to be rather low. Note that WiFi results may vary a lot depending on your setup.

I repeated the same file transfer, but with a 885MB file, for Gigabit Ethernet, and the average performance (10.05 MB/s) is somewhat OK, but I got the same behavior as with MINIX NEO U1 with the transfer much faster for download (16.4MB/s) , and slower for upload (7.64 MB/s).

Throughput in MB/s – Click to Enlarge

Since in most case the eMMC flash is the bottleneck for file transfers over Gigabit Ethernet, I also ran iperf -t 60 -c server_ip -d to test raw dual duplex performance, and it’s not too bad:

Miscellaneous Tests

Bluetooth

MINIX NEO U9-H advertises itself properply as NEO U9-H, and not some other funny code, and I had no problems pairing it with Vernee Apollo Lite Android smartphone, and could transfer a few photos. I could also connect X1T bluetooth earbuds and used it while watching some YouTube videos. I skipped Sixaxais app testing (for PS3 gamepads) since the firmware is not rooted.

Storage

My USB hard drive has four partitions for NTFS, EXT-4, exFAT and BTRFS, and only the NTFS/exFAT partitions could be mounted. A FAT32 micro SD card could also be mounted

File System Read Write
NTFS OK OK
EXT-4 Not mounted Not mounted
exFAT OK OK
BTRFS Not mounted Not mounted
FAT32 OK OK

USB storage performance was tested with A1 SD bench app, and read performance was very good (for a USB 2.0 port) with both file systems, but as usual exFAT is very slow to write to @ 6.66 MB/s.

The results were very good for the internal storage with 119.86MB/s read speed and 45.99 MB/s write speed. Note that the read speed is cached, meaning it should be faster than if read directly on the storage device itself, but probably not that different considering theoretical read speed is 285 MB/s for the flash, probably lower for the eMMC controller in Amlogic S912.

Internal Storage Read & Write Speed in MB/s – Click to Enlarge

Overall I found that applications started fast, and I had no slowdown or “app not responding” due to I/O access to the eMMC flash.

USB Webcam

I connected the UVC webcam to the box shown in the first picture of this review, logged in to Skype, and successfully run the Echo/Service audio call test, and made a video calls. I had problems last year for MINIX NEO U1 on Google Hangouts, but NEO U9-H works perfectly well with Google Hangouts.

Gaming

Amlogic S912 is know a well known platform, as gaming works just as well as on other devices, if not better since cooling is well implemented.  First, I played Candy Crush Saga with NEO A2 air mouse, and switch to Tronsmart Mars G01 wireless gamepad to play Beach Buggy Racing using maximum graphics settings. Both games played perfectly smoothly. As with other Amlogic S912, Riptide GP2 is a bit more demanding, playing very smoothly with default settings, the framerate felt lower with maximum graphics settings, probably around 25 fps most of the time, with some drops to ~15 fps from time to time.

I also played both 3D racing games for a total of 30 minutes, and performance was constant throughout, meaning the large heatsink is doing its job in preventing CPU and/or GPU throttling.

MINIX NEO U9-H Benchmarks

CPU-Z correctly reports an octa-core Cortex A53 processor @ up to 1.51 GHz with a Mali-T820 GPU. The model number is NEO-U9-H (q200), with 10.89 GB internal storage, 14790 MB RAM, and a framebuffer resolution set to 1920×1080.

Click to Enlarge

The first time I ran Antutu 6.x, the device achieved about 38,500 points quite lower than 41,000+ points I got in most other Amlogic S912 TV boxes. I ran it a short time after boot, so maybe there was background tasks at the time, I retried later, I got a 40,543 points, more in line with other competing TV boxes.

I also ran Vellamo 3.x benchmark to double check for issues.

MINIX NEO U9-H achieved 1,239 points, 912 points and 2,338 points for respectively multicore, metal and Chrome Browser tests, which compares to 1,130, 1,012 points and 2,758 points (Not Chrome Browser, Stock Browser). Multicore results has a yellow mark because it failed one of the test, just like M12N, but not other Amlogic S912 boxes:

Sysbench issue with Finepar: Invalid CPU mode

Conclusion

MINIX did again a good job with MINIX NEO U9-H thanks to very good hardware, stable & responsive firmware implementation, working smoothly at all times thanks to good thermal design. 4K video playback works well, I think it’s the first time I see automatic frame rate switching work on Amlogic S912 processor,  and audio pass-through is working fine with TrueHD and DTS-HD. The first version of the firmware also has less bugs than the one I reviewed on MINIX NEO U1 media hub, and slightly better performance. NEO U9-H also adds new features such as HDR, 4K VP9 decoding, Dolby & DTS license used for audio downmixing in all apps, and DRM Widevine Level 1 + Microsoft PlayReady. The only real downside compared to NEO U1 is that WiFi performance is not quite as good, despite using the same Ampak wireless module.

  • Video Output – HDMI 2.0 up to 2160p 60Hz; 24/25/30/50/60 Hz refresh rates supported; HDR should be supported too (not tested)
  • Very good Kodi 17 support with 4K H.265 (10-bit), VP9 and H.264 video playback,automatic frame rate switching
  • Dolby 5.1, Dolby+7.1, DTS HD and TrueHD audio pass-through working via HDMI and S/PDIF (for supported formats).
  • Dolby & DTS license means those audio formats work in all apps.
  • Well implemented power handling with off/standby/reboot mode, managed via an upgradable MCU, low off and idle power consumption
  • Widevine L1 and MicroSoft PlayReady DRM suppored
  • USB webcam working with Skype and Google Hangouts
  • OTA firmware upgrade with frequent update expected (based on previous models history)
  • Active support forums

CONS (and bugs)

  • Some videos with AC3 have micro audio cuts when HDMI pass-through is enabled, at least on my AV receiver. The problem goes away via optical S/PDIF
  • TrueHD dowmixing to stereo audio did not work in MX Player and Video Player apps.
  • WiFi performance is below average for both 802.11n and 802.ac, but similar to other Amlogic S912 TV boxes. Your mileage may vary. [Update: See comments’ section. WiFi performances looks, but combining SAMBA + WiFi is problematic. Likely an Amlogic Android 6.0 SDK issue]
  • List of apps shown in chronological order instead of alphabetical
  • A few videos do not play smoothly in Kodi but should: VP8 @ 1080p, one 10-bit HEVC video with no audio, “elephant dream” sample, “HD DVD” sample.
  • Potential buffering issue with some rare videos – Starts fast, plays for 1 or 2 seconds, buffers for 10 seconds then play again normally

If you’re going to spend the money on MINIX NEO U9-H, I really recommend you add NEO A2 Lite or NEO 3 air mouse, with the latter adding microphone input. Both air mice have the same design, feel comfortable in your hand, and work well as remote control, air mouse, and keyboard, as long as it’s for typing short texts like search query, user name / password, etc…

If you already own MINIX NEO U1, there’s probably little reason to upgrade, as performance will feel similar, except if you need 4K VP9, HDR, Widevine L1, or/and Microsoft PlayReady DRM support.

MINIX NEO U9-H media hub + NEO A3 air mouse sell for $159.90 / 149.90 GBP on Amazon US and Amazon UK, and are listed on GeekBuying, GearBest, and other online retailers with sales starting officially on March 3rd outside of Amazon.

I first found out about DragonBoard 820c, when I covered DragonBoard 600c development board last summer, but at the time there was not enough information to write a separate article. The board has now been listed on Arrow, and appears very similar to 600c board, so we have a few more details including basic preliminary specifications:

  • SoC – Qualcomm Snapdragon 820
  • System Memory – 3 GB LPDDR4
  • Storage – 32 GB UFS Flash + micro SD slot, maybe an mSATA slot?
  • Video Output – HDMI 2.0

  • Misc – Volume, power & reset buttons. 6 LEDS (4x user, 1x Wifi, 1x Bluetooth)
  • Power Supply – +6.5 – 18V DC input
  • Dimensions – 100 x 100 mm compliant with 96Boards CE Extended specifications

The page on Arrow states that:

This board only supports the Android operating system at this time.  There is NO Linux support for this board from Arrow, Qualcomm, or Linaro.org.  Only the Hardware Manual and Android User Manual are available as documentation.

However, a Wiki page on Linaro website explains how to install Debian and Open Embedded on the board, and DragonBoard 820c is supported by the Yocto Project, or at least there’s work done on it.

Contrary to the other boards, DragonBoard 820c does not appear to be available just yet, and price is  not known either.

Review of Ebox T8 V Amlogic S912 TV Box with SATA Bay – Part 1: Specs, Unboxing and Teardown

January 19th, 2017 9 comments

Last summer I reviewed Ebox T8-4, an Android TV box based on Amlogic S905 processor sold by entertainmentbox.com and geared towards the UK market. Although it had some of the typical issues with HDMI audio pass-through, I found the box easy to setup, and potentially interesting for UK viewers since popular IPTV apps were pre-installed. It also came with a SATA bay but for some reasons I never managed to have either a 1TV HDD or 128 GB SSD recognized by the system. Nevertheless, the box is now used full time by another person who seems to be quite happy about it, especially since it comes with an air mouse and a gamepad, and good support. The company has now sent me their updated model, Ebox T8 V, with very similar features but instead equipped with Amlogic S912 octa-core processor. Before checking the firmware, I’ll have a look at the hardware in the first part of the review.

Ebox T8-V Specifications

Apart from the SATA bay and VFD display, the specifications are pretty standard for an Amlogic S912 TV box:

  • SoC – Amlogic S912 octa-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3
  • System Memory – 2GB DDR3
  • Storage – 16GB eMMC flash, SD slot up to 32GB, and internal 2.5″ SATA bay
  • Video Output – HDMI 2.0 and RCA composite ports
  • Audio Output – HDMI, RCA stereo audio ports, and optical S/PDIF
  • Connectivity – Gigabit Ethernet, dual band WiFi 802.11 b/g/n/ac. N.B.: no Bluetooth listed in specs, but they sell a Bluetooth gamepad so it might be supported.
  • USB – 3x USB 2.0 ports (including one OTG port) + 1x micro USB port
  • Misc – IR receiver, power button, VFD display
  • Power Supply – 5V/3A

The box runs Android 6.0 operating system with SPMC.

Ebox T8-V Unboxing

Beside “T8 V SMART TV BOX” package I also got an air mouse (the same as last year), a EU to UK plug adapter, and something packaged with cardboard and tape.

Click to Enlarge

Let’s open that first… That’s a 1TB WD Blue hard drive, which means I should probably already be setup, and I would not need to use a separate computer to partition and format it a way supported by the box.


The air mouse remote is the same as last year (S77 Pro), and includes a standard IR side with IR learning function, mouse functionality…

Click to Enlarge

…as well as a QWERTY keyboard side. The battery compartment is located on the right side of the keyboard and takes two AAA batteries.

Click to Enlarge

The first thing I noticed when opening the main package was a piece of paper (top right below) reading:

Because the T8 V is operating on Android 6.0, you will need to adjust the settings a bit. Let’s go into Settings, then click on Video, go to the bottom and change Settings Level to Expert. Now go to the Acceleration Tab, then over to Allow Hardware Acceleration – Amcodec, and turn it off. You need to do this, because with the introduction of the new Android 6.0, Amcodec is no longer being supported, which can cause issues with the Ebox Media Center.

This could probably be useful to change those Kodi settings for other Amlogic S905X, S905D, and S912 TV boxes too. I’m not sure why it is not disabled by default in the firmware however.

Click to Enlarge

The rest of the package includes an IR remote taking two AAA batteries which you are unlikely to use at all if you have purchased the air mouse, a 5V/3A power supply, an HDMI cable, a HDMI cable, and of course the device itself.

Click to Enlarge

The front panel has a power button, as well as plastic cover hiding the IR receiver and VFD display. Two USB ports, the SD card slot, and a recovery button can be found on one of the sides, with the other ports on the rear panels including a USB OTG port (full size), a micro USB port market USB HDD, an optical S/PDIF audio output, 3 RCA connector for video, left and right audio, a HDMI 2.0 port, a Gigabit Ethernet port and the power jack. The gap under the box should allow for some cooling of the hard drive. If you want to connect the hard drive, you’ll need open the cover on the bottom of the case. There’s also a sticker with a MAC address starting with 00:11:6E and looking up to Peplink International Ltd.

Installing the hard drive is very easy and does not require any tool. Two clips hold the back cover to the case, and then you just need to insert the HDD in the bay, and push it to plug it into the SATA connector. Put the cover back, and you’re done.

Ebox T8 V Teardown

The first step to open the device is to loosen the four screws on the bottom of the case. This will allow you to remove the plastic cover on the front panel, and then push and slide the device to take it out of its outer shell.

Click to Enlarge

The board is called U PLUS V1.1, and features a heatsink covering Amlogic SoC. Foresee NCEMBSF9-16G eMMC flash is used for storage (16 GB), while two NANYA NT5CB256M16DP-EK chips are used for memory on the top of the board.

Click to Enlarge

Gigabit Ethernet is made possible thanks to Realtek RTL8211F Gigabit transceiver and HS2401 magnetics, and WiFi connectivity relies on an uncommon module, but I could not read the exact model. Since Amlogic S912 does not integrate a SATA controller, the board designer used GL830 USB 2.0 to SATA bridge. TM1628 chip takes care of the VFD display, and GL850G USB 2.0 hub adds a few extra USB interface required by the board.

That’s all for today. If you are interested, the box is for sale directly on Entertainmentbox.com for 104.99 GBP ($129.5) with the standard remote, and up to 217.97 GBP (~$269) with full options including a 1TB HDD, Rii i12 Keyboard, and an Ipega gamepad. The package I received should cost 185.97 GBP (~$229). Prices include VAT.

Eweat R9 Plus TV Box Review Part 2 – Android, OpenWrt, and HDMI Recording

December 24th, 2016 25 comments

Eweat R9 Plus is a device powered by Realtek RTD1295 SoC combining main functions: Android 6.0 TV box, OpenWrt NAS/router, and HDMI recorder thanks to its HDMI input port. It competes directly with Zidoo X9S which has the same features, except while Zidoo X9S has no internal SATA bay and your 2.5″ hard drive just hang outside the box, Eweat R9 Plus comes with an internal 3.5″ SATA bay that makes it much neater on your furniture… We’ve already seen that in the first part for review “Eweat R9 Plus unboxing and teardown“, and I was impressed by the hardware, but the software is even more important, and that’s what I’m going to check out in the second and final part of this review.

First Boot, First Impressions and Setup.

I’ve first inserted a 1TB 3.5″ SATA drive in the device, and then I connected an extra USB 3.0 hard drive, HDMI and Ethernet cables, two USB dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, and a USB keyboard to take screenshots, as well as U4 Quad Hybrid Android TV box to the HDMI input.

Connect the power, press the mechanical power switch on the back, and the device will boot, typically in about 40 seconds, to the main launcher. There’s no setup wizard like in Zidoo X9S, so you’d have to change configuration separately.

Click to Enlarge

Click to Enlarge

The top left corner includes status icons for USB, Ethernet, Bluetooth, and WiFi, and the top right corner shows the current date and time. The first time the time and date were not correctly update, and I did not get any IP address from my router… That’s because I connected the Ethernet cable to the WAN port, but once I connected it to the LAN port, everything worked fine. It’s just WAN and LAN markings are not quite correct…. Let’s go back to the launcher with 7 large icons, the “R9 Plus” icon is linked to Chrome browser (so we have two Chrome links), apps to the list of apps, EWMC links to Kodi 16.1, and 4K to the local file browser/media player. We also have 3 shortcuts on the botton that can be customized to your needs. Sadly, there’s no status nor notifications bars which can be a pain in some use cases. The small blue “rocket” on the of EWMC icon, is actually the mouse cursor (red in reality, but the screenshot app turns that blue).

The system comes with a bunch of apps including Netflix, HDMIRecorder, and QuickSupport, and I could install my own without any issues using Google Play and Amazon Underground.

eweat-r9-plus-displayThe front panel display on the unit is a little more useful than most, as it will show the current time of the day when not playing videos or music, and instead display the current video time with 4K video player, but not Kodi, while playing media files.

If you are interested to find out more about the settings, I invite you to check the Settings section of Zidoo X9S review, as Eweat R9 Plus has basically the same settings, except only “Auto 1080p24” option is available in the Display section, Deep Color Mode (AUTO, 12-bit, 10-bit, OFF) is gone, and the Playback section is missing together with “Auto 29.97/59.94 Hz”, “Force SD audio”, “Enable low performance mode (less buffer for playback)”.

I could set the resolution (“TV System”) to 3840x2160P @ 60Hz without any issues, but I’ve noticed the video output will sometimes fall back to 720p or 1080p after a power cycle. I could not find any option to adjust overscan either, so I had some black zone on all edges of my TV. Those are issues, but the latter at least should be easy to fix via firmware upgrades.

Once I found that LAN is actually WAN, and WAN is LAN, I had no troubles at all with Ethernet and WiFi, and OpenWrt options are also exactly the same as on Zidoo X9S.

You only get 9.31GB of the 16GB in Android because some part is reserved to OpenWrt, but it still more than the 8.91GB I had on X9S. In theory it should be plenty enough, but after a day or two of use, my internal storage was completely full, despite not installing that many apps.

android-storage-fullEventually I found that since my 1TV hard drive had millions of files, Android’s “Media Storage” activity had created two very large databases. Disabling Media Storage fixed the issue, and after clearing the data from “Media Storage” I had close to 8GB free. Alternatively you can add an empty .nomedia files in the directory you do not want to system to scan, for example the root of the harddrive if you don’t want it to scan anything.

Going into the About device section, we can see “R9Plus” model runs Android 6.0.1 on top of Linux 4.1.17.

about-device-r9plusThe firmware is rooted, and OTA firmware update is done with SystemUpdate app, and I could upgrade from R9PLUS_V1.1_20161130 version to R9PLUS_V1.02_20161217 version which I used in most of the review. I had to disconnect the USB drive, or the update will fail. You can leave the SATA drive inside the box during firmware upgrades.

eweat-r9-plus-firmware-updateThe update went well, and did not mess with my settings, apps, and media files.

The included IR remote worked fine up to 10 meters, but I’d really wish higher end devices such as R9 Plus would ship with an air mouse by default. I had to jungle between the IR remote control and MINIX NEO A2 Lite air mouse quite often depending on the app I used. Realtek apps such as HDMIRecorder, 4K media player, and File Manger may work better with the infrared remote control.

Eweat R9 Plus firmware is stable and responsive, but there are a few small bugs here and there that should be fixed, like the lack of screen scale option, video output resolution set by the user is not always used after a reboot, there’s no status nor notification bars, etc… I’d also wish such higher-end systems would come with an air mouse with keyboard by default to be able to fully control the TV box with a single remote.

Power Consumption and Temperature

Power control support is basic with only on or off, no standby or reboot, but the power consumption numbers are OK, albeit a little higher than Zidoo X9S, maybe because of the 3.5″ SATA drive instead of 2.5″ SATA drive:

  • Power off (SATA HDD) – 0.3 Watt
  • Idle (SATA HDD) – 9.2 Watts
  • Power off + SATA & USB HDD – 0.3 Watt
  • Idle + SATA & USB HDD –  11.2 to 12 Watts
  • SATA HDD (Copy file to SAMBA share) + Play 4K video from USB HDD + miniDLNA in the background – 18 to 19 Watts

If you has a drive with many files, miniDLNA – enabled in OpenWrt settings as DMS (Digital Media Server) – will take a lot of CPU and I/O resources, so if you don’t need it, make sure to disable it. Idle power consumption numbers are with DMS disabled.

While there’s no standby mode, we’ve seen with Zidoo X9S that standby mode is not that useful as networking and drives are all turned off. It’s just must faster to boot than from power off mode. Most cheap Android TV boxes cannot handle more than one USB hard drive, but Eweat R9 Plus had no troubles with a SATA hard drive and a USB 3.0 drive. It might be possible to add yet another USB 3.0 drive, as the power supply has a 30 Watts capacity.

It’s no surprise that with a large metal case, the device stays relatively cool at all times. The maximum temperatures measured with an IR thermometer on the top and bottom of the device were 35 and 37 °C respectively after Antutu benchmark, and 40 and 50 °C after playing Riptide GP2 for 15 minutes.

Video & Audio Playback with Kodi 16.1 and 4K App, Antutu Video Tester, and DRM Support

R9 Plus comes with Kodi 16.1 (EWMC) and 4K app to browse and play media files with the internal player. So I’ve started by testing 4K videos with both. Bear in mind that while Realtek RTD1295 supports 10-bit HEVC/H.265 up to 60 fps @ 4K, H.264 is limited to 24 Hz, which will be a problem with you shot 4K H.264 30 fps videos with a camera or your smartphone, and 4K VP9 @ 60 fps is supposed to be supported, and with DDR4 memory I had hope some progress may be made here, but unfortunately the limit is really 30 fps, which could be an issue with some (downloaded) YouTube videos. Out of Specs videos are prefixed with OoO.

For some reasons Kodi 16.1 will fail to start playing some videos the first time, but play them the second time. Just like on Zidoo X9S – but worse – Kodi 16.1 implementation is not as good as the internal player, so for best user experience you’d have to use the 4K player. Automatic refresh rate switching works with 4K app, with 23.975/24Hz, 25 Hz, 29.97 Hz and 59.94 Hz with the latest firmware. It does not work at all with Kodi.

For so the audio tests, I’ve stopped using Kodi, and only used 4K app with PCM 2.0 downmixing and audio pass-through via HDMI.

Audio Codec in Video PCM 2.0 Output HDMI Pass-through
AC3 / Dolby Digital 5.1 OK Audio OK (DD 5.1), but wrong aspect ratio
E-AC-3 / Dolby Digital+ 5.1 OK OK (DD 5.1)
Dolby Digital+ 7.1 OK OK (Dolby D+ 7.1)
TrueHD 5.1 OK OK (TrueHD 5.1)
TrueHD 7.1 OK OK (TrueHD 7.1)
Dolby Atmos 7.1 OK TrueHD 7.1
DTS HD Master OK OK (DTS-HD MSTR)
DTS HD High Resolution OK OK (DTS-HD HR)
DTS:X (not supported by Onkyo TX-NR636) OK DTS-HD MSTR

So HDMI audio pass-through is working very well, and I did not experience some of the audio cuts I had on Zidoo X9S with Onkyo TX-NR636 receiver. Those may have been fixed since Zidoo X9S review however.

Below are a few screenshots from 4K video app starting with the list of storage devices/partitions…

I’ve also quickly tested Blu-ray ISOs (Sintel and Amat videos) and both could play. Finally, I play a 2-hour 1080p video to make sure the system can play a full movie, which I does.

Antutu Video Tester score (820 points) is a little lower than on Zidoo X9S (888).

eweat-r9-plus-antutu-video-testerBut the videos that failed are exactly the same:

zidoo-x9s-antutu-video-tester-resultsDRM info crashed each time, just like on X9S, so there’s problably no DRM support at all.

HDMIRecorder App

Eweat R9 Plus HDMIRecorder, as its name implies, allows you to record video from an HDMI input source. It can record up to 1080p @ 30 fps using H.264 codec in TS or MP4 container format, with a bitrate up to 10Mbit/s.

It will also record audio, and you can select the output with the “Path” field. It will create a new “hdmi” directory to store the recorded videos.

Once recording has started, it will work in the background (see recording info in the top right corner below) and you can browse the web, watch other videos, and so on during recording.

I could then connect to the device via SAMBA, and play with the recorded video with both Totem player ad VLC in my Ubuntu 16.04 computer.

That part works fine, and looks similar to Zidoo HDMI In app, however it lacks some goodies like PiP support and UDP broadcasting found in Zidoo X9S. So if so those functions are important to you, Zidoo X9S clearly has an edge of Eweat device here.

OpenWrt and NAS functions

If you want to learn more about settings up OpenWrt on Eweat R9 Plus, I’ll redirect you to OpenWrt and NAS functions section of Zidoo X9S review as all features are identical.

You can control OpenWrt main functions in Android settings…

… and fine tune OpenWrt settings through LuCi web interface.

I tested SAMBA, FTP, and Bittorrent. Performance on Eweat R9 Plus was very good with FTP transfer at ~105 MB/s, and 40 MB/s for SAMBA file copy to the internal SATA, very similar to Zidoo X9S with respectively about 90 MB/s and 50 MB/s.

Eweat R9 Plus FTP Transfer – Click to Enlarge

Eweat R9 Plus SAMBA Transfer

Contrary to my experience with Zidoo X9S, BitTorrent worked just fine and the transfer quickly saturated my 20 Mbps Internet connection.

eweat-r9-plus-bittorrentBear in mind that firmware evolves overtime and it’s quite possible Zidoo has already fixed the issue.

This time I also tested OpenWrt opkg system manager to see if it would work. After connecting to the device through ssh, I tried to update the packages and it failed miserably:

So if you want to install packages, you’d probably have to build them yourself, or copy and install opkg packages built for ARM architecture manually.

WiFi Performance

We’ve already seen Gigabit Ethernet works perfectly above with transfers at 105 MB/s through FTP basically saturing the Gigabit Ethernet bandwidth, so I’ll only focus on WiFi in the network performance section. Eweat R9 Plus has excellent WiFi performance with both 802.11n @ 2.4 GHz, and 802.11ac (433 Mbps), roughly matching Zidoo X9S equally good performance.

All you need to know is that Eweat R9 Plus is one of the top devices for WiFi  for all devices I’ve tested over the year.

Miscellaneous Tests

Bluetooth

I could pair Vernee Apollo Lite Android smartphone with “Realtek Bluetooth”, however once I started transferring files from my phone to the device, I either got the message “Unfortunately Bluetooth has stopped”, and when lucky, the transfer was initiated with Eweat R9 Plus showing an overlay message reading “”Incoming file from another device, please confirm…”. That’s all good but since there’s no notification bar, and no pop-up window, I had no idea where to confirm the transfer, and it eventually time out. I could not test Bluetooth Low Energy, because all my device are either broken or lost.

Bluetooth is not completely useless however, as I could get Sixaxis to work with my PS3 BT gamepad clone, and I paired X1T Bluetooth earbuds successfully, and listen to a YouTube video.

Storage

Eweat R9 Plus could mount NTFS, EXT-4, and NTFS partitions on a 1 TB USB 3.0 Seagate expansion harddrive with only BTRFS failing to be recognized. A FAT32 micro SD could also be mounted in read/write mode, as well as my SATA drive formatted with NTFS.

File System Read Write
NTFS OK OK
EXT-4 OK OK
exFAT OK OK
BTRFS Not mounted Not mounted
FAT32 OK OK

A1SD bench app shows excellent sequential read and write for the SATA interface, a decent performance for all supported file systems through USB 3.0:

  • USB 3.0 + NTFS – Read: 37.93 MB/s – Write: 39.28 MB/s
  • USB 3.0 + EXT-4 – Read: 37.67 MB/s – Write: 39.43 MB/s
  • USB 3.0 + exFAT – Read: 37.04 MB/s – Write: 39.28 MB/s
  • SATA + NTFS – Read: 140.78 MB/s – Write: 86.30 MB/s

Eweat R9 Plus looks faster than Zidoo X9S using SATA + NTFS, but bear in mind that the hard drive used was different, so it may explain the difference. However, Zidoo was quite better for USB 3.0 using EXT-4 and NTFS, but quite poor for exFAT, which R9 Plus appears to support well.

I also measured internal storage performance, but unfortunately A1SD bench reported “Cached Read”, so the read speed is not valid. The write speed of about 55 MB/s is valid, and this is quite good. The actual read speed in the chart below should be lower than 140+ MB/s, but usually read speed is faster than write speed, so performance should still be good.

Gaming

I played Candy Crush Saga with the air mouse, and Beach Buggy Racing (with max quality) using a gamepad, and both games played perfectly well. Then I switched to Riptide GP2, again with maximum resolution settings. It’s started begin playable – but not quite 60fps – just like on Amlogic S905/S912 TV boxes, and Zidoo X9S, but then I noticed the image would freeze from time to time, and after a race was completed,  it may have a 10 seconds black screen before going to the main menu. So I checked the CPU usage in OpenWrt (SSH terminal), and notice miniDLNA with a high CPU usage. So I disabled DMS in Android’s OpenWrt settings, miniDLNA stopped running, and I could play the game for 15 minutes more without issues, nor performance degradation over time.

Eweat R9 Plus Benchmarks

Let’s start with CPU-Z.. R9PLUS (rtk_kylin32) model with a quad core Cortex A53 processor @ 1.4 GHz and a Mali-T820 GPU, so no surprise here.

The device reached 36,076 points in Antutu 6.2 against 34,976 points for Zidoo X9S Antutu score.
eweat-r10-plus-antutu

There are a few potential explanations for the small difference: 1. R9 Plus firmware is more recent, 2. it’s winter here (~ 22 °C), and 3. R9 Plus has DDR4 ram instead of DDR3 RAM. However the strange thing is that R9 Plus RAM score is 3,046 points, but Zidoo X9S got 3,960 points which does not make any sense.

eweat-r9-plus-vellamo
Vellamo 3.x scores are pretty similar with R9 Plus getting 1,430, 881 and 2,539 points for respectively multicore, metal, and Chrome Browser benchmarks, against 1,457, 831 and 2,638 points for Zidoo X9S. So it looks like DDR4 memory does not help for any benchmarks, including 3Dmark’s Ice Storm Extreme.

4,359 points for Eweat R9 Plus against 4,574 for X9S.

Conclusion

Eweat R9 Plus is a solid device, and I really like the internal 3.5″ SATA bay, internal and external storage, as well as networking performance is really outstanding too. However I would have wished the firmware to have fewer bugs, and just like for Zidoo X9S, Realtek RTD1295 SoC has some limited 4K capabilities when it comes with H.264 and VP9. Getting the optimal performance may require some tweaks like disabling some server services.

PROS

  • Responsive and stable Android 6.0 firmware
  • 4K app plays 4K H.265 videos very well with automatic frame rate switching, and HDMI audio pass-through for Dolby TrueHD and DTS HD audio
  • Excellent Ethernet and WiFi performance
  • Excellent internal and SATA storage performance, and good USB 3.0 performance
  • NTFS, EXT-4, exFAT, and FAT32 file systems are well supported
  • HDMI Input (up to 4K60 input) with video recording up to 1080p30 (4K input is also supported but record at 1080p30 max)
  • OpenWrt NAS functions such as SAMBA, FTP, and BitTorrent running at the same time as Android, as well as router functions thanks to its two Gigabit Ethernet ports
  • Proper power handling with power off, standby, and reboot, and low power consumption in off/standby modes. The provided 36W power supply also allows the connection of multiple hard drives.
  • Dolby & DTS audio licenses are included, so audio will work in any apps
  • OTA Firmware update
  • Good hardware design with internal 3.5″ SATA bay

CONS (and bugs):

  • Realtek RTD1295 VPU limitations:
    • 4K H.264 up to 24 fps which will be an issue for 4K videos recorded with some actions cameras (GoPro/Xiaomi Yi) and smartphones
    • 4K VP9 up to 30 fps, as 60 fps is not well supported. This will be an issue for some 4K videos downloaded from YouTube
  • Kodi 16.1 (EWMC) is not really working that well with many 4K videos not playing smoothly (even those within specs) and automatic frame rate not working. So 4K app is recommended
  • No DRM support (DRM info app will crash)
  • HDMI input works, but does not include features like picture-in-picture and UDP broadcasting found in Zidoo X9S
  • You’ll probably have to use both the include IR remote control AND a air mouse or other input device to fully use the device. A air mouse specifically designed for the box would be a plus.
  • Scale screen option missing in firmware, so I had black edges on my TV the whole time (should be easy to fix with firmware update)
  • No option for status and notifications bars
  • Bluetooth file transfer is unreliable (crash) and there’s no way to confirm file transfer (related to notification bar above)
  • Tweaks may be needed (e.g. disable Media Storage and DMS) for optimal performance if you have a hard drive with many files.
  • The system will not always remember the video output set by the user (e.g. 4K 60 Hz set, but falls back to 1080p or 720p).

Eweat also lacks a community forum like Zidoo, but as long as they keep firmware updates rolling, it may or may not matter to you. Overall, Eweat R9 Plus is also a good device combining 4K TV box, OpenWrt NAS, and HDMI recording functions. Whether that’s right for you depends on your requirements and budget.

The manufacturer sent me the review sample directly. Distributors can inquire the company to purchase in quantities, but if you just need one or a few you can purchase it on Aliexpress for $175.99 plus shipping (about $200) on Aliexpress.

Merry Christmas to all!
