Pine64 produces some boards and sells them. It uses the Allwinner A527 or T527 SoC, and comes with the following features: - Eight ARM Cortex-A55 cores, Mali-G57 MC1 GPU - 1GiB/2GiB/4GiB LPDDR4 DRAM - AXP717 + AXP323 PMIC - Raspberry-Pi-2 compatible GPIO header - 1 USB 2.0 type A host port, 1 USB 3.0 type A host post - 1 USB 2.0 type C port (OTG + serial debug) - MicroSD slot - eMMC between 16 and 128 GiB - on-board 16MiB bootable SPI NOR flash - two 1Gbps Ethernet ports (via RTL8211F PHYs) - HDMI port - DP port - camera and LCD connectors - 3.5mm headphone jack - (yet) unsupported WiFi/BT chip - 1.3" LC display, connected via SPI - 12 V barrel plug for power supply Add the devicetree file describing the currently supported features.
