This is a 4GB Class-10 microSD card that will come with a Debian Linux image installed for the A20-OLinuXino-MICRO or A20-OLinuXino-MICRO-4GB board. The image will be the same freely available build that you can download from the A20-OLinuXino-MICRO Wiki Page. Purchase this when you want to get up and running with the board quickly rather than having to download and write the image yourself.

Display Setting The Debian image comes set up to use HDMI 720p @ 60Hz. The Wiki page has instructions for changing to an LCD or VGA display, or for changing the HDMI settings, e.g. to 1080p.
Enabling Ethernet By default, the image has Ethernet disabled, to improve startup times for those who aren't using it. Use the command "ifconfig -a" to find out the name that the LAN is associated with, then use the command "dhclient xxxx" (where xxxx is the name of the LAN, e.g. it may be eth0) to enable the Ethernet and make SSH available. Note then that if you ever disconnect your Ethernet cable, the board will take a long time to boot up.
