This is a 4GB Class-10 microSD card that will come with an Android 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.
Note: The A20-OLinuXino-MICRO-4GB version of the board already comes with the equivalent Android image installed in its NAND Flash. With that board, you'd only need this SD card if you intend to replace the OS in the NAND Flash with the Debian Linux build and want Android as a secondary OS — and you don't want to have to write the image to your own SD card (or perhaps you don't have a card writer to do so).
There are two versions of the Android build. Both support HDMI and LCD output; the difference is in what size LCD is supported. By default, this SD card will include the build with support for the 7-inch LCD at 800×480 resolution. At your request, we can instead install the build with support for the 10.1-inch LCD at 1024×600 resolution.
