ERS-RB01 Brushless Tachometer
The ERS-RB01 measures brushless motor RPM directly from any two ESC output wires and sends real-time data to your EdgeTX radio via CRSF telemetry. It also supports pass-through expansion for easy daisy-chaining with additional ERS sensors.
Features
- Accurate RPM Monitoring: Captures real-time brushless speed with high precision.
- ExpressLRS Integration: Sends RPM data directly to compatible ExpressLRS receivers via the CRSF interface.
- Multi-Unit Support: Connect multiple ERS-RB01 sensors to monitor several units simultaneously.
- Versatile Applications: Ideal for any application requiring accurate RPM feedback.
- Compact & Lightweight: Easy to install without adding significant weight.
- Plug-and-Play: Quick setup with minimal wiring for fast deployment.
Real-Time Brushless RPM Monitoring Setup
Most brushless systems support RPM monitoring. Pins can be reassigned via Web UI or LUA script to enable accurate telemetry (200–30,000 RPM, 98.1% accuracy) while keeping remaining channels free for servos or ESCs.
ExpressLRS PWM Sensor Setup
Most PWM receivers support external sensors. Reassign two PWM pins via Web UI or LUA script to enable telemetry while keeping other channels free for servos or ESCs.
