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.

Plug and Play Compatible Receivers:

Using Sensors with Non-Plug-and-Play PWM ExpressLRS Receivers:

Most PWM ExpressLRS receivers are fully compatible; those without a dedicated UART port require reconfiguration to support external sensors (e.g., for telemetry). To enable this, reassign two PWM output pins as a serial UARTone for TX and one for RXvia the receiver’s Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while
