Features
- Accurate Engine RPM: Monitors gasoline engine speed in real time with precision.
- ExpressLRS Integration: Sends RPM data directly to compatible ExpressLRS receivers via the CRSF interface.
- Versatile Applications: Ideal for any application requiring accurate RPM feedback.
- Compact & Lightweight: Easy to install without adding unnecessary weight.
- Plug-and-Play: Simple connection to the CDI output for fast setup.
Sensor Setup for PWM ExpressLRS Receivers
Most PWM ExpressLRS receivers support external sensors. For receivers without a dedicated UART, two PWM pins can be reassigned as TX/RX through the receiver Web UI or ExpressLRS LUA script, enabling sensor connectivity while keeping the remaining PWM channels available for servos or ESCs.
Real-Time Engine RPM Monitoring
Monitor engine RPM in real time through your EdgeTX radio, with 200–30,000 RPM range and ±0.1% accuracy for precise engine feedback.
Plug & Play Compatibility
Designed for plug-and-play use with compatible ExpressLRS receivers, making RPM sensor installation quick and easy without additional configuration.
