Description

Open source hardware and open source software A20 Linux board with 0.1" step connectors for easier access and evaluation.

We offer several variants of this board. Aside from the base version we offer a variant with extra eMMC or NAND flash memory (suffix -e4G, -e16G, or -n8G); we have a variant with 16M SPI flash memory (suffix -s16M). We also have variants of the board suitable for industrial temperature range of operation (-40+85)C - these come with the "T2" chip and have "-IND" suffix in the name.
