RadioMaster ERS-RC01 CDI Gas Engine Tachometer for Compatible ExpressLRS PWM Receivers

The ERS-RC01 Gasoline Engine Tachometer measures RPM by connecting directly to your engine's CDI speed output. The sensor accurately detects engine speed, transmits the data to a compatible ExpressLRS receiver through the CRSF interface, and then sends it back to your EdgeTX radio for real-time monitoring. Ideal for any application requiring accurate RPM feedback.

As part of the ERS sensor family, the ERS-RC01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.
