OpenPilot ESC

Features

Compact form factor
Probably good for 40-50A (needs testing, I haven’t got the transistors hot yet)
2S-4S capable
Very high speed response
Self testing with diagnostic codes for failure
Tunable control loops to optimize for various motors and props. I’ll have good values for some common ones.
Accurate current monitoring with soft limit (slows RPM to keep at the current limit) and emergency shut down for higher limit
Closed loop control so input determines precise RPM, regardless of prop size, etc
PWM control for standard compatibility. I2C/Serial/CANBus support for bidirectional communications for monitoring.
Configurable settings for current limit, control loop coefficients, RPM range
