MK823 Android Set-Top Box Features AllWinner A31s SoC

AllWinner A31s is a cost down version of AllWinner A31 quad core Cortex A7 processor that is designed for phablets, with support for lower LCD and camera resolutions. This means A31s may actually be better choice than A31 for media players since few make use of LCD and/or camera interfaces. MK823 is the first media player I’ve heard of that use A31s processor.

MK823

Here are the specifications of the device:

  • SoC- Allwinner A31S quad-core Cortex A7 @ 1.0 GHz with PowerVR SGX544 MP2 GPU
  • System Memory – 1GB DDR3
  • Storage – 8GB NAND Flash + SD card slot (up to 32GB)
  • Video Output – HDMI 1.4
  • Connectivity:
    • 10/100M Ethernet
    • 802.11 b/g/n Wi-Fi
    • Bluetooth 4.0
  • USB – 3x USB 2.0 Host port (including one OTG)
  • Power Supply – 5V/2A
  • Dimensions – N/A
  • Weight – N/A

This 4.2.2 Android TB box comes with a 5V/2A power adapter, an HDMI cable, a USB cable, and a user’s manual. The device sells for about $70 including shipping on Aliexpress, and I could also find it on Ebay for $89 including shipping. The price is quite competitive compared to low cost RK3188 Android TV Boxes such as K-R42-1 or Jesurun K8. The Cortex A7 used in AllWinner A31s has much lower performance than the Cortex A9 used in RK3188, but in Android the GPU is just has important, and the PowerVR-544 MP2 in A31s will in many cases outperform Mali-400 MP4 in RK3188. MK823 has less RAM than the other two devices, but unless you run many application simultaneously, it should not affect performance that much. If you intend to use the device as a cheap Ouya with a Bluetooth game controller, gaming performance should be pretty good.

In case you wonder about Linux support, there’s some work going on AllWinner A31, but development is pretty slow compared to AllWinner A20, and companies doing development boards based on Chinese SoCs such as Olimex or CubieTech, appears to focus their development efforts on RK3188 instead of A31(s) for their upcoming quad core boards. That means for Linux support platforms based on AllWinner A31 / A31s may not be the best choice.

I have also tried to find the manufacturer but without success. But if you want to buy in quantities, Cozyswan (Shenzhen Realtime M&C) is selling the device in Alibaba, and some companies mention the model name is either “KG-161″ or “KG-158″.

    I also wonder about Android support for A31 – I’ve seen quite a lot of reports of A31 devices shipping with firmware problems…

    I did have issues (and still have with more recent firmware) with CS868 mini PC, and other also had issues on the same device, as well as Mele A1000G Quad. I haven’t checked about A31 tablets, but this category must be very important to them so they may have better firmware.

    i would not touch a31 or a31s with a ten foot pole the firmware is not good on tablets or tv boxes i have ampe a85 which is running on the a31s and i have wifi and video issues also the 8″ tablet freezes every now and then even when there is not too much load so maybe hardware acceleration not working 100% and there is no working android 4.2. firmware iam still waiting for a decent firmware for my cs868. also i installed couple of different firmware for both devices i still think rockchip is the safe bet i never had problems with my mk808 and mk908
