Shenzhen Xunlong has already been selling 64-bit ARM development board with their Orange Pi PC 2 & Orange Pi Zero Plus 2 H5 boards based on Allwinner H5, as well as Orange Pi Win board powered by Allwinner A64 processor.
However, so far none of them are equipped with much memory, with the only options being 512MB or 1GB RAM. The company has recently launched two new boards with 2GB RAM, namely Orange Pi Win Plus featuring Allwinner A64 SoC, and Orange Pi Prime equipped with Allwinner H5 SoC.
The company has released Android, Ubuntu 16.04 “Xenial” Server & Desktop, and Debian Jessie Server & Desktop images for the board on the resources page. Windows 10 IoT support is coming later thanks to a partnership between Allwinner and Microsoft. It’s also possible community images will also become available.
