Boards in 1 GitHub repository, designed in KiCad, that use the CH549F by WCH (Nanjing Qinheng Microelectronics) (12bit 3.3V~5V 48MHz 51 Family 64KB FLASH QFN-28-EP(4x4) Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the CH549F’s symbol, footprint and pinout are on its own page.
