A20-OLinuXino-LIME is OSHW certified Open Source Hardware with UID BG000038

A20-OLinuXino-LIME is a compact (84x60)mm Linux open source hardware computer
We offer several variants of this board. Aside from the base version we offer a variant with extra eMMC or NAND flash memory (suffix -e4GB, -e16GB, or -n8GB); we have a variant with 16MB SPI flash memory (suffix -s16MB). 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 expecting 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 a Debian or Android image for A10-OLinuXino-LIME or 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-LIME. The prepared cards which we sell for the board are also different.
  • What do I need to connect one of the Olimex-made displays to the board?
  • At the moment you would need two 40 pin cables (named CABLE-40-40-10CM and CABLE-IDC40-15cm) and a small adapter board called A10-OLinuXino-LIME-UEXT. In future, a single cable would be avaialable.
  • I bought a supported LCD display and the required cables but when I connect it to the A20-OLinuXino-LIME I receive no image on the display. What do I do wrong?
  • The default A20-OLinuXino-LIME Debian image is set for HDMI output and FullHD 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-LIME?
  • The board works in the commercial temperature range 0+70C
  • How long this board will be available?
  • This board will be available forever
