[Sticky] RPM Smart-Port Sensor
The FrSky Smart Port RPM and Temperature Sensor has been designed to work with FrSky Smart Port systems, it can measure the RPM of brushless motors from 1,000~30,000rpm and temperatures of -20 to 250 degrees celsius. Other FrSky Smart Port enabled sensors including the variometer, lipo voltage, GPS, current and airspeed sensors can be used at the same time.
Installing is easy, just connect the sensor to any 2 wires on the brushless motor by the supplied JST cable and then plug the smart port lead into the smart port enabled receiver. 2 temperature sensors are supplied which are plugged to the PCB so you can use a single one or both. Attach the temperature sensor to your ESC to enjoy the full benefit and peace of mind from this fantastic product. Set up is very straightforward using the push button and LED status indicator.
Please note: The FrSky Smart Port RPM/Temperature Sensor is only compatible with FrSky Smart Port enabled receivers such as the X8R, X6R and X4R.
