Powers a arduino nano and small stepper motor. Used in a flip number clock radio. It doesn't emit too much noise unlike some switching power supplies would. Read more

These are small. I was able to fit two of them in a 2.4"W x 2.2"H x 1.3"D box. Hot glued down. AC voltage in, and two sets of 5V out for two USB ports for charging. Neat little boards, and a neat little project. Put them on a guitar pedal board because somebody always needs to charge their damn phone or tablet on stage. Read more
