Boards in 1 GitHub repository, designed in KiCad, that use the MMSTA42 by Jiangsu Changjing Electronics Technology (CJ) (-55℃~+150℃ 1 NPN 200mA 200mV 250nA 300V 300mW 50MHz 5V 60 NPN SOT-323 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the MMSTA42’s symbol, footprint and pinout are on its own page.
