Boards using the LM393

386 boards

Boards in 295 GitHub repositories, designed in KiCad, that use the LM393 by MSKSEMI (-16V~16V 0℃~+70℃ 2 2.5mA 250nA 2V~36V 36V 5mV 5nA Fail-safe function Open-drain SOP-8 Comparators ROHS). See how each wires it, with its parts, size, README and files; the LM393’s symbol, footprint and pinout are on its own page.
