RadioMaster ERS-RB01 - Brushless Tachometer for Compatible ExpressLRS PWM Receivers 3" They have achieved this performanceThe 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
