About this product
The RadioMaster ERS-RB01 RPM-BLDC Sensor 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.
