Boards in 2 GitHub repositories, designed in KiCad, that use the LM339DT by STMicroelectronics (0℃~+70℃ 1.1mA 1.3us 1.3us 1V~18V、1V~18V 1mV 25nA 2V~36V 36V 5nA DTL、TTL、CMOS、ECL、MOS Four channels SOIC-14 Comparators ROHS). See how each wires it, with its parts, size, README and files; the LM339DT’s symbol, footprint and pinout are on its own page.
