moteus brushless servo
This contains full designs for the moteus brushless servo actuator, including firmware and PCBs.
WARNING: This is not just a software project. It includes designs for moderately high power electronics. It has not yet burned down my (or anyone's that I know of) house, but there are no guarantees.
