108 open source boards using the NCP1117-3.3_SOT223
Real designs built with the NCP1117-3.3_SOT223, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.
