44 open source boards in Robotics & motion
Motor drivers, servo and stepper controllers, flight controllers and robot boards. 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.
