One Response on “Dual Relay Driver Board

  1. Hello!
    Thank you for sharing the schematics and even the list of parts to buy. I’m not a pro with electronics, and I’d like to ask if you could add the different components one would need to use a 5V supply (of course, with 5V relays). I’m working with Arduino and I intend to build a 2 channel 5V relay board to control a garage motor and another security system.
    Once again, thank you for everything you’ve already shared!
