A20-OLinuXino-Micro is fully OSHW A20 based development board from our friends at Olimex.

This board was originally designed with the pin-compatible A10 in mind. While this design never shipped, Olimex can produce A10 versions of this board if you so desire.


The board helpfully reads "A20-OLINUXINO-MICRO".
