Mygica ATV1900AC Android Lollipop TV Box Unboxing and Teardown

Geniatech sent me two samples of their latest Android devices this morning with Mygica ATV1900AC TV box powered by Amlogic S812 quad core Cortex A9 processor, and Mygica ATV586 DVB-T2 receiver powered by Amlogic S805 quad core cortex A5 processor. Beside relatively high-end specs with 802.11ac, Gigabit Ethernet, 2GB RAM, and 16GB eMMC, one of the former main selling point is the Android Lollipop firmware that is said to brings significant improvement over Android 4.4 KitKat. But today, I’ll focus on the hardware side with pictures of the devices and its internals, before writing the results of my tests in a few days.

Mygica ATV1900AC Unboxing

Geniatech sent me both boxes in a DHL parcel, and both are Mygica branded retail packages. Mygica ATV1900AC packages shows some of its key features like Android Lollipop support, 4K UHD, H.265, 802.11ac WiFi, voice search and so on…

Most TV boxes ship with a useless IR remote control, but ATV1900AC comes with a small air mouse with its USB RF receiver and two AAA batteries, as well as as an HDMI cable, a 5V/2A power supply (EU plug for my sample), and a quick Start Guide in English only.

A close look at the device reveals a power button, IR receiver and LED on the front panel, four USB 2.0 host ports on the side, and the remaining ports on the rear panel including a micro SD slot, a reset pinhole, HDMI output, a Gigabit Ethernet port, optical S/PDIF, and the DC jack. You’ll have notice an placement for an RF connector, so there may be a version with digital tuners in the work, or the enclosure is used for other models too.

You’ve also got two external Wi-Fi antennas: one for 2.4GHz, one for 5.0 GHz.

You can watch the unboxing video too if you please.

Mygica ATV1900AC Teardown

On the bottom of the case, we’ll find a screw holding a cover for what looks like a 2.5″ SATA bay. Once we remove the only screw and take out the cover, there’s indeed a space for 2.5″ drive, but unfortunately there’s no SATA connector, so that enclosure must definitely be used for other models.

ATV1900AC_SATA_Drive_BayTo take the device further apart, you’ll need to remove the two rubber pads close to the WiFi antennas, remove the two screws underneath, as well as two more screws located in the “SATA bay”. Then you can turn over the device in upward position, and use a sharp and hard plastic tool to pop-up the top cover.

We’ll see the bottom of the board, but there’s not much to see here, so let’s loosen three more screws so take the PCBA out.

There’s some sort of cooling pad on top of the processor, but it’s not a heatsink, nor your typical thermal pad, as it’s quite hard. The silkscreen on the board reads “R&D_hfy RMG0129 VER 1.2”, four NANYA NT5CB256M16CP-D1 DDR3 chips provide 2GB RAM, and we get 16GB storage with a Toshiba THGBMBG7D2KBAIL eMMC 5.0 flash with theoretical 50MB/s write speed, and 270MB/s read speed in HS400 mode. Geniatech also chose a WiFi SoC that I have not often seen in other boxes with Realtek RTL8812AU chip using a USB interface, and supporting 802.11 b/g/n and 802.11ac in 2×2:2  MIMO configuration according to Wikidevi. There’s also a Linux driver for this Realtek chip. Other components include two GL852G USB 2.0 hub chips, and Realtek RTL8211F Gigabit Ethernet transceiver.

The hardware looks very interesting, and although I don’t think Amlogic S812 supports HS400 mode, I’m expecting fast boot and app loading times thanks to the Toshiba eMMC, and very good 802.11ac performance. We’ll see how that turns out.

Mygica ATV1900AC is now in mass production, and distributors can get the box from Mygica/Geniatech. The Android box is also listed on eBay for $179.99 including shipping, and should soon show up on Mygica Aliexpress store.

Could you please test this device with 10bit HEVC video. I know from Amlogic specs that S812 does not have 10bit HEVC support, but I was wondering whether Android 5.0/5.1 can help in playing this video format.

10bit profile is HW limitation. It’s possible that there are some improvements in displaying 10bit video, but 10bit will properly work on S905 and newer chips.

$199 will get you the Nvidia Shield set top box which is superior in every single way along with the proper AndroidTV OS and actual Netflix 4K support.

This thing is a waste of money for anyone other than Chinese market.

[…] to see the progress made compared to devices that run Android KitKat. I’ve already taken apart the TV Box, and found some interesting Toshiba eMMC flash and Realtek 802.11ac WiFi chips on the board, but […]
