Olimex A20 OLinuXino Single Board Computers are open source software and hardware, low cost Linux computers manufactured in industrial -40ºC to +85ºC and commercial 0-70ºC temperature grades. Access all CAD files and sources and reuse them for personal or commercial projects. The A20 processors are pin-to-pin compatible. Pinout tables and GPIO maps for the A20-OLinuXino-LIME apply to the A20-OLinuXino-LIME2. Except for the 0.05" step connectors, LCD display and all the GPIOs connectors, which have a different layout compared to both A20-OLinuXino-LIME and A10-OLinuXino-LIME.
A20-OLinuXino-LIME2 looks similar to both A20-OLinuXino-LIME and A10-OLinuXino-LIME. The major differences between A20-OLinuXino-LIME2 and A20-OLinuXino-LIME are:
LIME2 has gigabit Ethernet (GbE), compared to the standard 100Mb Ethernet of the LIME
LIME2 design provides double the RAM memory, compared to the LIME design (1024 vs 512)
Much better routing of DDR3 memory.
Increased the number of layers from 6 in LIME to 8 in LIME2
Corrected pinout of the LCD and GPIO connectors (shields designed for the LIME layout are not compatible with the LIME2 layout)
