Description

The RadioMaster ERS-CU01 Real-Time Current Sensor delivers precise real-time current and voltage monitoring, giving pilots instant insight into power consumption, system efficiency, and overall aircraft performance directly on their EdgeTX radio through compatible ExpressLRS receivers. Designed for seamless inline installation with future-ready pass-through expansion, it enhances telemetry capabilities, improves power management, prevents overload conditions, and supports scalable sensor integration for advanced RC setups.

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.
