RadioMaster ERS-RB01 Brushless Tachometer for Compatible ExpressLRS PWM Receivers

The ERS-RB01 Brushless Tachometer measures RPM by tapping directly into any two wires of a brushless ESC output. The sensor captures precise speed data, sends it to a compatible ExpressLRS receiver via the CRSF interface, and relays the information 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-RB01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.
