RadioMaster ERS-RB01 RPM-BLDC Telemetry Sensor

The RadioMaster ERS-RB01 RPM-BLDC Telemetry Sensor monitors brushless motor speed in real time and sends RPM data through a CRSF interface to a compatible ExpressLRS receiver for relay to an EdgeTX radio.

It connects directly to two ESC output wires for RPM sensing. Pass-through ports support multi-sensor daisy chains, while the compact design provides plug-and-play installation for RC and robotics applications.
