Boards using the ULN2003AD

18 boards

Boards in 14 GitHub repositories, designed in KiCad, that use the ULN2003AD by Texas Instruments (1.7V 15pF 30V 500mA 50V 50uA 50uA Seven channels SOIC-16 Darlington Transistor Arrays ROHS). See how each wires it, with its parts, size, README and files; the ULN2003AD’s symbol, footprint and pinout are on its own page.
