Rockchip RK3188 Based QC802 mini PC Can Now Be Purchased for $65

When Rockchip RK3188 powered mini PC started to show up in March 2013, many were priced around $90, which some shops aggressively (and temporarily) pricing UG007B at $74. But it’s now possible to purchase QC802, a quad core mini PC with 2GB RAM and 8GB Flash, for just $61.75 excluding shipping from a seller with good feedback. Adding shipping will bring it to about $70 depending where you live, but applying “registernewbuyer5” coupon brings it back to $65 or even a bit less. QC802 is by far the cheap RK3188 device I’ve found. Just a quick reminder of the specs: SoC – Rockchip RK3188 quad core Cortex A9 @ 1.6 Ghz + Mali-400MP4 GPU System Memory – 2GB DDR3 Storage – 8 GB internal flash + micro SD slot (up to 32GB) Connectivity – Wi-Fi 802.11 b/g/n + Bluetooth 2.1 Video Output – HDMI (male) USB – 1x USB Host […]

Quick 3D Game Performance Comparison – Rockchip RK3188 vs AllWinner A31 HDMI TV Sticks

When comparing SoCs, most like to look at the overall score, and as I mentioned this morning, Tronsmart T428 (based on RK3188) easily beats Kimdecent CS868 (Based on A31) in Antutu benchmark, the former scoring 15207 points against 10559 points for the latter, both using stock firmware, and similar resolution (1280×720 vs 1280×672). The difference in resolution is because the status bar was hidden in T428. If we look at GPU performance, both the 3D scores in Antutu are about the same for both devices: T428 CS868 2D Graphics 1549 998 3D Graphics 2696 2866 But according to an earlier GPU comparison post, PowerVR SGX544 MP2 should be much faster than Mali-400 MP4. So I’ve decided to perform two quick tests: Epic Citadel benchmark and Real Racing 3 game. T428 could render Epic Citadel 1.07 at 41.3 fps in high quality, but I failed to install Epic Citadel, either via […]

Rockchip RK3188 Linux Source Code is Now Available

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs. Let’s have a look:

[Update: you may have to run “sudo apt-get install libc6-i386” before running make_kernel_ruikemei.sh below, as mkkrnlimg is a 32-bit binary] Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

After just over a minute, success!:

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188. Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs: rk3168_86v_defconfig rk3188_dongle_defconfig rk3188_ds1006h_defconfig rk3188_ds1006h_v1_0_defconfig rk3188_hotdog_defconfig rk3188_LR097_defconfig rk3188_magicwand_defconfig […]

$96 Kingnovel K-R42-1 (MK888) Android Set-top Box Powered by RK3188 Processor

I’ve now got several RK3188 mini PCs, but I hadn’t found full sized set-top boxes based on Rockchip RK3188 quad core processor with Ethernet, and multiple USB ports. Thanks to a post in mini PC G+ community, we have now a nice looking quad core STB called K-R42-1 by Kingnovel, which might be the manufacturer design house behind the device, and sold for  $96 including shipping in one Aliexpress store under the model name MK888. K-R42-1 / MK888 Specifications: SoC – Rockchip RK3188 quad Cortex-A9 CPU @ 1.6 GHz + Mali-400 MP4 GPU @ 500 MHz System Memory – 2GB DDR3 SDRAM Storage – 8GB Nand Flash +  MicroSD slot (Up to 32GB) Connectivity 10/100M Ethernet WiFi 802.11 b/g/n with external antenna Bluetooth EDR 2.0 Video Output – HDMI 1.3 + AV output jack Audio Output – HDMI + S/PDIF Video Codecs (Decode) – MPEG-1, MPEG-2, MPEG-4, H.263, H.264 (up […]

Geniatech PT115m and PT115e USB DVB-T Sticks Let You Watch Digital TV on Tablets and mini PCs

Last month, I wrote about Geniatech WiTV, a device with a DVB-T or ISBT tuner acting as a Wi-Fi access point that let you watch TV on any Wi-Fi enabled devices. I’ve just discovered Geniatech PT115m (microUSB) and PT115e (USB), tinier and probably cheaper products, which allow you to watch free-to-air channel (DVB-T) by connecting them to the USB or microUSB port of your tablet or mini PC. Both devices have the following key features and specifications: Geniatech HiDTV app for Android Watch DVB-T TV on Android tablet, with support for Electronic Program Guide, HDTV (1080i), and Automatic Station Searching Digital Personal Video Recording Input Terminal – VHF/UHF,  Receive Frequency – TV 48.25 ~ 863.25 MHz DVB-T Compliant,  2K to 8K FFT Size, Punctured Codes: 1/2, 2/3, 3/4 4/5, 5/6 and 7/8, Bandwidth: 6/7/8 MHz Stream capture – PES & TS Video Format – mpg-II Main Profile & Main Level/H.264 Mpeg4 […]

Kimdecent QC802 Review

QC802 is one of the cheapest RK3188 mini PCs available on the market, as it sells for just $76 on Kimdecent aliexpress store ($73 after you get an Aliexpress coupon). AndroidPC.es got one sample, and posted a review in Spanish. I’ll post a summary in English of this review, but first let’s have quick look at the specs: SoC – Rockchip RK3188 quad core Cortex A9 @ 1.6 Ghz + Mali-400MP4 GPU System Memory – 2GB DDR3 Storage – 8 GB internal flash + micro SD slot (up to 32GB) Connectivity – Wi-Fi 802.11 b/g/n + Bluetooth 2.1 Video Output – HDMI (male) USB – 1x USB Host 2.0, 2x micro USB ports including one for power, one USB Host (or OTG?) So the specs are comparable to other devices. QC802 Unboxing Pictures The package contains the device itself, a 5V/2Apower supply, an HDMI cable, a micro USB to USB […]

$88.50 Jesurun NX003II Quad Core mini PC Comes with a Webcam and an External Wi-Fi Antenna

Do you remember MK812, a dual core mini PC with a built-in camera, and an external high-gain Wi-Fi antenna? Well, I’ve just noticed a similar device called Jesurun NX003II on DealExtreme, but instead of the dual core processor (RK3066) and 1GB RAM, it comes with Rockchip RK3188 quad core Cortex A9 processor, 2GB RAM, and yes, the camera and external antenna are still there. Jesurun NX003II Specifications: SoC –  Rockchip RK3188 Quad core Cortex A9 @ 1.6Ghz with Mali-400 MP4 GPU System Memory –  2GB DDRIII Storage – 8GB NAND Flash + microSD card (up to 32GB) Connectivity: Wi-Fi IEEE 802.11 b/g/n with external Antenna Bluetooth v2.1 Video Output – HDMI 1.4 (1080p, 3D support) Video Codecs – MPEG1/2/4, H.264, VC-1, Divx, Xvid, RM8/9/10, VP6 Audio Codecs – MP3, WM, WMA, WAV, OGG, AAC, MPEG Audio, PCM LPCM, M4A, AC3, DTS Camera – Built-in 2.0MP camera USB – USB OTG […]

Wi-Fi Performance Comparison for Android Media Players and HDMI Sticks

If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]
