I am happy to show you the powerful Merrii A80 Optimus Board. It has A80 SoC manufactured by Allwinner Technology, that includes big.LITTLE octa-core ARM Cortex-A15/A7 CPU and PowerVR 64core G6230 GPU. The board also has 4GB RAM, 8GB internal storage as well as Bluetooth 4.0, WiFi, HDMI, 2 USB hosts and USB 3.0 On-the-Go.
A80 Optimus Board is shipped with a power supply and USB to serial cable for debugging through UART. More information about the board is available here.
Out of the box A80 Optimus Board boots to Android KitKat 4.4.2. It should be possible to use the board with newer version of Android such Lollipop as well as various Linux distributions: Debian, Ubuntu, Fedora, ArchLinux, etc. It should be also possible to boot the Linux-based software platform Tizen on this board.
