39 open source boards in Test & measurement
Oscilloscopes, logic analyzers, current sensing and lab instruments. Every board here is a public GitHub project with its KiCad files, read for size, layers and parts. Pick one close to your design and simulate its firmware on HardLabs before you build it.
