Iteaduino plus A20

Iteaduino plus A20 is an open hardware development plattform, built around Allwinner A20 SoC with a dual-core ARM A7 processor. The plattform can be used both as a complete computer that runs Linux and as a very powerful and compact micro controller. The processor board can be removed from the main board, and since all the schematics and pcb files are released, it's relatively easy to design a new board for use in DIY projects.
