A20-OLinuXino-LIME2 user's manual
A20-OLinuXino-LIME2 looks similar to both A20-OLinuXino-LIME and to A10-OLinuXino-LIME. The
major differences between A20-OLinuXino-LIME2 and A20-OLinuXino-LIME are:
1. LIME2 has gigabit Ethernet (GbE), compared to the standard 100Mb Ethernet of the LIME.
2. LIME2 design provides double the RAM memory, compared to the LIME design (1024 vs 512).
3. Much better routing of DDR3 memory.
4. Increased the number of layers from 6 in LIME to 8 in LIME2.
5. Corrected pinout of the LCD connector (shields for LIME are not compatible with LIME2)
6. The price tag
Due to the hardware differences listed above the Linux and Android distributions of the LIME2 and
LIME boards are not identical. Furthermore, some of the hardware extensions are not compatible with
both of the designs. For example, the
A10-OLINUXINO-LIME-UEXT
is
not
compatible with A20-
OLinuXino-LIME2 board.
