Welcome to the wiki of the linux-sunxi community, an open source software community dedicated to Allwinner based devices.


What is sunxi

sunxi represents the family of ARM SoC (System on Chip) designed for embedded systems, and design by Allwinner Technology fabless semiconductor company based in Zhuhai (Guangdong, China). The most popular of Allwinner's sunxi SoC models are currently the pin-compatible A1x and A2x series which are the Allwinner A10, A13, A20, A23, A31 and A33. Their predecessor was an ARM9 named Boxchip F20 (sun3i), and their successors are Allwinner A31 and A80. See Allwinner SoC Family for more information.


The sunxi community is a very active and advanced one. For more information, check our linux-sunxi community page. It explains how to get help and how to contact us, and how you can contribute as well.

Allwinner based devices

Due to the popularity of the Allwinner SoCs, there are literally thousands of different devices out there.

If you are looking for support for your device from the sunxi community here, please take a look at our guide to identifying your device. If you cannot find your device, then you might need to work through our new device howto.

If you are interested in buying an Allwinner SoC based device, then read through our buying guide.
