Boards using the BC857
138 boardsBoards in 117 GitHub repositories, designed in KiCad, that use the BC857 by STMicroelectronics (1 PNP 100MHz 100mA 15nA 200mW 45V 5V 650mV 800 PNP SOT-23 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the BC857’s symbol, footprint and pinout are on its own page.
