Radiomaster ERS-RC01 Plug and Play CDI Gas Engine Tachometer for Compatible ExpressLRS PWM Receivers

Description:
The ERS-RC01 Gasoline Engine Tachometer measures RPM by connecting directly to your engine’s CDI speed output. The sensor accurately detects engine speed, transmits the data to a compatible ExpressLRS receiver through the CRSF interface, and then sends it 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-RC01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.
Feature:
1. Accurate Engine RPM: Monitors gasoline engine speed in real time with precision.
2. ExpressLRS Integration: Sends RPM data directly to compatible 3. 3. ExpressLRS receivers via the CRSF interface.
4. Versatile Applications: Ideal for any application requiring accurate RPM feedback.
5. Compact & Lightweight: Easy to install without adding unnecessary weight.
6. Plug-and-Play: Simple connection to the CDI output for fast setup.
