Boards in 1 GitHub repository, designed in KiCad, that use the KTC3875 by Jiangsu Changjing Electronics Technology (CJ) (-55℃~+150℃ 1 NPN 100nA 150mA 150mW 250mV 50V 5V 70 80MHz NPN SOT-23 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the KTC3875’s symbol, footprint and pinout are on its own page.
