The ERS-CU01 Current Sensor is a compact telemetry module designed for use with compatible ExpressLRS (ELRS) receivers. Installed inline between the battery and ESC, it measures real-time current and voltage data and sends it to your EdgeTX radio through the receiver. This provides clear insight into system load, efficiency, and power consumption.

As part of the ERS sensor family, the ERS-CU01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.

Features

Real-Time Current Monitoring: View live current draw and voltage directly on your radio to better understand system performance and prevent overload conditions.
Inline Installation: Soldered between the battery and ESC for accurate, full-system current measurement.
Future-Ready Pass-Through: Includes in-and-out ports for daisy-chaining additional ERS sensors as your telemetry needs grow.
Seamless ExpressLRS Integration: Designed to work smoothly with compatible ExpressLRS PWM receivers.

Real-Time Voltage and Current Telemetry

High-power systems support direct plug-and-play monitoring. This module enables real-time current and voltage tracking (70V max, 150A burst) with high accuracy, keeping remaining outputs free for servo or ESC control.

ExpressLRS Plug-and-Play Telemetry

Supports direct plug-and-play for most ExpressLRS receivers (e.g., EP1/EP2/Nano). For others, easily reassign PWM pins via Web UI or LUA script to enable real-time telemetry.
