Boards in 1 GitHub repository, designed in KiCad, that use the PMGD280UN by YTL (1 N-channel 13pF 150mW 20V 270mΩ@4.5V 700mV 750mA 750pC 79pF 9pF N-Channel ±12V SOT-363 MOSFETs ROHS). See how each wires it, with its parts, size, README and files; the PMGD280UN’s symbol, footprint and pinout are on its own page.
