780 open source PCB designs, indexed by the chip they’re built around
Real boards from 256 public GitHub repositories, read straight from their KiCad files: size, layers, the full parts list and a render of the PCB. Find one close to what you’re building, then simulate its firmware on HardLabs before you order anything.
