BLDC 3 phase motor speed controller hardware design working with open source BLHeli_S C configuration firmware C_H_30.
The esc is tested with real quadcopter up to 40A current rating per motor. Power MOSFETs on esc are capable of delivering current up to 45A for normal operation and 90A peak for short pulse.
Phase C has current bar trace. Or it can be done with extra solder on the trace.
