Radiomaster ERS-CU01 Current Sensor

The RadioMaster ERS-CU01 Current Sensor is a compact telemetry module for use with compatible ExpressLRS receivers. Installed inline between the battery and ESC, it measures real-time operating current and voltage for display on your EdgeTX radio. This provides instant insight into system load, efficiency, and power consumption across your entire powertrain. Check out all of the Sensors and our entire RadioMaster selection at RaceDayQuads. Features View live current draw and voltage directly on your radio to better understand system performance and prevent overload conditions Inline installation for accurate, full-system current measurement Supports daisy-chain expansion for additional ERS telemetry sensors as your setup grows Seamless ExpressLRS integration Compact & Lightweight 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.
