RPM Sensor Hobbywing

Hobbywing RPM sensor for high-voltage ESCs

The RPM sensor is an accessory for high-voltage ESCs. It detects the voltage changes in the wires to the brushless motor and outputs an RPM signal, so it can be used with several helicopter flight control systems, typically as the RPM sensor for Mikado's V-Bar system.

Wires A and B connect to any two of the motor wires, with no need to worry about polarity. Wire C is a three-colour lead with a plug: black is ground, red is supplied with 3.3 V or 5 V, and white carries the RPM signal.
