Is only difference between A20-OLinuXino-LIME and A20-OLinuXino-LIME2 size of ram and speed of ethernet? Thank you.
Mainly the RAM size and the Ethernet speed as you wrote but also:
- LIME is 6-layer PCB, LIME2 is 8-layer PCB;
- GPIO and LCD connectors have different layouts between the two boards, so shield boards like LIME2-SD and LIME2-SHIELD are only compatible with A20-OLinuXino-LIME2.
