FPGA based retrocomputer with FDD and HDD controllers
Boards in 42 GitHub repositories, designed in KiCad, that use the BC856 by Nexperia (-65℃~+150℃ 1 PNP 100MHz 100mA 125 15nA 250mW 300mV 5V 65V PNP SOT-23 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the BC856’s symbol, footprint and pinout are on its own page.
