What is sunxi

sunxi represents the family of ARM SoC (System on Chip) designed for embedded systems, and made by Allwinner Tech. in Zhuhai (Guangdong, China). The most popular sunxi SoC model is the Allwinner A10 and the Allwinner A13. Their predecessor was an ARM9 named Boxchip F20 (sun3i) and their successors are A20 and Allwinner A31. See Allwinner SoC Family for more information.

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, 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.

Open Source Hardware

At sunxi we fully support the OSHW initiative, as this gives people the freedom to adapt hardware designs to their own needs. Currently, Olimex is the only company creating Allwinner based OSHW, and Olimex actively contributes to the sunxi project.
