A20-OLinuXino-MICRO

EMBEDDED ARM LINUX COMPUTER WITH ALLWINNER A20 1GB RAM AND MEGABIT ETHERNET

Linux-enabled Allwinner A20 development board with Ethernet, HDMI output, 1GB DDR3 RAM memory, two SD card connectors, plenty of free GPIOs and much more.
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.
