Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible "ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC. The R-01 contains only the CPU, DRAM, and always-on voltage regulation; it does not merit a separate devicetree. The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an X-Powers AXP228 PMIC for managing a Li-ion battery. The DevTerm is a complete system which extends the ClockworkPi mainboard with a MIPI-DSI panel and a pair of expansion boards. These expansion boards provide a fan, a USB keyboard, speakers, and a thermal printer.
