Installed inline between the battery and ESC, it measures real-time operating current and voltage sending the data through the ExpressLRSreceiver for display on your EdgeTX radio. This provides instant insight into system load, efficiency, and power consumption across your entire powertrain.\u003c\/p\u003e\n\u003cp\u003eAs part of the ERS sensor family, the ERS-CU01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReal-Time Altitude Telemetry: Converts barometric pressure measurements into accurate relative altitude data for instant feedback on your radio.\u003c\/li\u003e\n\u003cli\u003eExpansion-Ready Pass-Through: Includes an in-and-out port for daisy-chaining additional ERS sensors without rewiring your setup.\u003c\/li\u003e\n\u003cli\u003eSeamless ExpressLRS Compatibility: Integrates easily with supported ExpressLRS PWM receivers via CRSF for fast and dependable data transmission.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlug and Play Compatible Receivers:\u003c\/p\u003e\n\u003cp\u003eER6 2.4GHz ExpressLRSPWM Receiver\u003c\/p\u003e\n\u003cp\u003eER8 2.4GHz ExpressLRSPWM Receiver\u003c\/p\u003e\n\u003cp\u003eER8G \u0026amp; ER8GV ExpresersLRS PWM Receiver\u003c\/p\u003e\n\u003cp\u003eUsing Sensors with Non-Plug-and-Play PWM ExpressLRS Receivers:\u003c\/p\u003e\n\u003cp\u003eMost 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.\u003c\/p\u003e\n\u003cp\u003eFor 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).
