Upgraded and improved version of A20-OLinuXino-LIME with double the RAM and Gigabit Ethernet
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 16MB 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.

- I am an inexperienced user and I'm afraid to mess up initially. What are the most common errors in the initial start-up of the board?
- The best idea is to download the latest Debian or Android image from the wiki and to pay attention if it is for microSD card or the NAND memory. After that ensure the image is properly written to the SD card or the NAND memory. Finally, if you are experiencing video output problems, ensure the image is set with the proper settings for the display/monitor you are going to use. Double check if the power supply is sufficient (especially if powering a display from the board).
- Can I use the Linux or Android image for A20-OLinuXino-LIME or A10-OLinuXino-LIME instead of the one for A20-OLinuXino-LIME2?
- No. Both Debian and Android images are specfic for each board. Make sure the image that you download and use is specifically marked as suitable for A20-OLinuXino-LIME2. The prepared cards which we sell for the board are also different.
- Hello, I made a shield for my LIME board. I now own a LIME2 board. Can I use the shield with the LIME2 design?
- No. The LIME2 design swaps the signals of each row of each 0.5" step header. All four GPIO headers and the LCD header are affected. Shields made for LIME boards can't be connected directly to a LIME2 board.
- I bought a supported LCD and the required cables but when I connect it to the A20-OLinuXino-LIME2 I receive no image on the display. What do I do wrong?
- The default A20-OLinuXino-LIME2 Debian image is set for HDMI output and HD resolution. To use LCD or lower the resolution you would need to start the shell script in the default Debian image.
- What is the operating temperature range of A20-OLinuXino-LIME2?
- The board works in the commercial temperature range 0+70C.
- How long this board will be available?
- This board will be available forever.
