Boards using the CJ2301

18 boards

Boards in 14 GitHub repositories, designed in KiCad, that use the CJ2301 by Jiangsu Changjing Electronics Technology (CJ) (-55℃~+150℃ 1 P-Channel 142mΩ@2.5V 1V 2.3A 20V 400mW 405pF 55pF 75pF P-Channel SOT-23 MOSFETs ROHS). See how each wires it, with its parts, size, README and files; the CJ2301’s symbol, footprint and pinout are on its own page.
