The sensor connects to two of the three wires that lead to the motor. After setting the number of poles, the sensor can calculate the motor speed. The sensor is also equipped with two temperature probes to measure the temperature of any component.
- Calculate how many magnet pairs your motor has.
- Connect the supplied JST connector cable to any two of the three wires leading from the speed controller to the engine.
The engine in the picture has 7 pairs magnets
- Plug the RPM sensor into the receiver and the receiver to power.
- Long press the button on the RPM sensor until the red LED stays on.
- Keep pressing the button until the desired value is set on the LEDs 0-4.
In our case, 7 pairs of magnets will light up LEDs 0, 1 and 2, LED 3 will be off.
- Disconnect the power from the receiver after setup.
Taranis should be set to 1 in the telemetry settings.
Two temperature probes can measure any equipment such as BEC, battery, engine, etc.
