This is the same as the F1C100s, but with 64MB instead of 32MB co-packaged DRAM. Alongside the obligatory micro-SD card slot, the board features a SPI-NAND flash chip, LCD and touch connectors, and unpopulated expansion header pins. There are two USB Type-C ports on the board: One supplies the power, also connects to the USB MUSB OTG controller port. The other one is connected to an CH340 USB serial chip, which in turn is connected to UART1. Add a devicetree file, so that the board can be used easily.
