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.
