Up to now at least three boards based on Allwinner A80 processor were available: A80 OptimusBoard by Merrii, pCDuino8 by Linksprite, and Cubieboard4 by Cubitech, and the first two boards are basically the same. Merrii has now introduced a new board which they call “A80 Hummingbird H8”, with more features and ports including HDMI, VGA and eDP video outputs, LVDS / MIPI DSI display interfaces, MIPI CSI camera interface, an RTC with battery and more.

Based on my experience with A80 OptimusBoard, Merrii does not always provide full documentation and source code for their board. But either A80 OptimusBoard came out a little too earlier, or Merrii has decided to improve, as some documentation (mostly in Chinese), and source code has been released on their forums.
Other downloads include:
- A80 HummingBird H8 Android image (Android 4.4.2 with Linux 3.4.39)
- A80 HummingBird H8 Lubuntu images for SD card or internal boot (I guess)
- A80 HummingBird H8 SDK (5.51 GB) – a80_hummingbird_20141015ok.tar.gz (password: 96qo)
I’m not sure when the board will be available, and but it should eventually show up on Merrii Aliexpress store.
