Radiomaster ERS-RB01 RPM-BLDC

Overview:
The RadioMaster ERS-RB01 is a dedicated brushless motor tachometer sensor engineered for use with ExpressLRS PWM receivers. It taps into any two ESC output wires to capture precise motor speed data and relays that information over CRSF telemetry to a compatible radio running EdgeTX. The sensor’s small size and low weight make it suitable for a wide range of RC applications where real-time RPM feedback improves performance monitoring and tuning.

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.
