RadioMaster ERS-CU01 Current Telemetry Sensor
About this part
Sensor Overview
The RadioMaster ERS-CU01 Current Telemetry Sensor is a powerful tool for monitoring the electrical performance of your RC system in real time. Designed to work seamlessly with compatible ExpressLRS receivers, it provides accurate insight into current draw and voltage directly on your transmitter.
About the ERS-CU01 Current Telemetry Sensor
Real-Time Power Monitoring With Expandable Telemetry
The ERS-CU01 measures live current and voltage, transmitting the data through your ExpressLRS receiver for display on an EdgeTX-compatible radio. This allows you to monitor system load, detect inefficiencies, and avoid overload conditions during operation. Its inline installation ensures accurate full-system readings, while the pass-through ports make it easy to expand your telemetry setup by daisy-chaining additional ERS sensors. Designed for seamless integration, it works with plug-and-play receivers or can be configured for broader compatibility using UART reassignment.
