Boards using the BAT42

57 boards

Boards in 42 GitHub repositories, designed in KiCad, that use the BAT42 by STMicroelectronics (-65℃~+125℃ 200mA 30V 4A 500nA@25V 650mV@50mA Independent DO-35 Schottky Diodes ROHS). See how each wires it, with its parts, size, README and files; the BAT42’s symbol, footprint and pinout are on its own page.
