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.
Plug and Play Compatible Receivers:
Using Sensors with Non-Plug-and-Play PWM ExpressLRS Receivers:
Most PWM ExpressLRS receivers are fully compatible; those without a dedicated UART port require reconfiguration to support external sensors (e.g., for telemetry). To enable this, reassign two PWM output pins as a serial UART—one for TX and one for RX—via the receiver's Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while preserving the remaining PWM channels for servos or ESCs.
For receivers that only provide standard servo pins, an optional adapter cable is available that converts the sensor’s UART connector to two standard servo plugs (TX and RX). Available here: https://radiomasterrc.com/products/ers-sensor-uart-to-dual-pwm-adapter
Sensor Configuration & Telemetry Logging
To configure this sensor and view telemetry on your EdgeTX radio, install the RadioMaster Sensor Configurator LUA. The LUA allows adjustment of sensor settings, enables proper telemetry display, and supports data logging for post-flight review.
After downloading, connect your radio to a Mac or PC in USB-SD mode.
