Description The RadioMaster ER5C-i receiver is based on the high-performance, revolutionary ExpressLRS system, featuring high reliability, highly flexible configuration, ultra-fast response speeds, and an ultra-long receiving range, bringing with it a brand-new usage experience. The ER5C-i ELRS receiver can drive up to 5 servos and has built-in receiver voltage telemetry and battery telemetry with the ability to automatically detect which voltage input to use. The ER5C-i features a built-in high-sensitivity ceramic antenna, it is designed for all types of surface models and provides a clean install without antenna wires to worry about. Features Built-in high-sensitivity ceramic antenna Based on the Revolutionary ExpressLRS System High performance, high reliability, flexible configuration, fast response speed and ultra-long range Supports 3 PWM Channels Automatically detects voltage telemetry of external battery voltage or receiver battery / ESC BEC voltage Optimized ground up PCB design Supports Wi-Fi updates and WEBUI configuration Built-in a TCXO (temperature compensated crystal oscillator), ensures stable and accurate performance in any environment Designed for all types of surface models Compatible with all 2.4GHz ExpressLRS modules and transmitters with built in 2.4GHz ExpressLRS Specifications Item: ER5C-i 2.4GHz ELRS PWM Receiver Power supply: DC 4.5 – 8.4V Antenna type: Built-in high-sensitivity ceramic antenna Wireless protocol: ExpressLRS 3.3.0 pre-installed Output channel: 5CH PWM Telemetry power: 10mW Battery voltage detection range: DC 4.0 – 35V Weight: 5.0 grams Dimensions: 30.0*18.5*13.0 mm Firmware: Device Category: Radiomaster 2.4Ghz / Device: RadioMaster ER5C-i TCXO The TCXO (temperature compensated crystal oscillator) ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. Click to learn more about the TCXO.
