$37 GK328 Android mini PC Powered by Rockchip RK3028 Dual Core Processor

Rockchip RK3028 is a low cost dual core Cortex A9 processor pin-to-pin compatible with RK2928 single core Cortex A9, I first heard about at Hong Kong Electronics Fair 2013. It’s now found in a few kids tablets, as well as GK328, an Android 4.2 HDMI TV dongle, that sells for about $37, or a few dollars cheaper than similar AllWinner A20 or Rockchip RK3066 based devices.

GK328 specifications:

  • SoC – Rockchip RK3028 dual core Cortex A9 @ 1.0 GHz with Mali-400 GPU
  • System Memory – 512MB RAM
  • Storage – 4GB NAND flash + microSD card slot
  • Video & Audio Output – HDMI
  • Connectivity – 802.11b/g/n Wi-Fi
  • USB – 1x USB HOST 2.0, 1x micro USB OTG, 1x micro USB for power
  • Misc – Fn button (for recovery?)
  • Power – 5V/1A via micro USB port

The device runs Android 4.2 and sells with a power adapter, a USB cable, an HDMI cable, and a user’s manual. This must be one of the cheapest, if not the cheapest dual core Cortex A9 mini PC, but I’m not so sure many will be interested, as for about $5 more, you can get MK808 with Rockchip RK3066 with better performance, 1GB RAM, and 8GB Flash, as well as decent community support. One advantage is that RK3028 is apparently more power efficiency, and works with a 5V/1A powered adapter, whereas MK808 requires a 5V/2A power adapter to run reliably.

    i just bought one of these and i will do a comparison between this and the HTV003 (Telechips 8935) see which one is more usable and less problems and which one is faster better ui xbmc support.

    And also i was very lucky to buy one HTV003 because as soon as i bought one they took it off aliexpress and if you want to buy you can only buy minimum 500 units.

    Anyone found a upgrade for RK3028a? What I have is a variant of MK808-B with the following spec:
    rockchip 3028A 1.6 Ghz SoC
    nanya NT5CB512MBCN-DL 512Mx2 DDR RAM
    micron 29F32G08CBADA 4G Flash
    Esp8089 WIFI soc
    and currently it has 4.2.2, but the playstore just crashes, and I can only install apps via adb or FileExpert. I can run Kodi 16.1 on it, and it seems to be working well.

    Does this device get detected via rockchip’s flash tool?
