Boards using the 817B

Boards in 1 GitHub repository, designed in KiCad, that use the 817B by UMW (-30℃~+100℃ 1.2V 100mV@20mA,1mA 200mW 35V 3us 4us 50% 50mA 50mA 5kV 600% 6V DC Phototransistor DIP-4 Transistor, Photovoltaic Output Optoisolators ROHS). See how each wires it, with its parts, size, README and files; the 817B’s symbol, footprint and pinout are on its own page.
