RadioMaster ER8 2.4GHz ELRS PWM Receiver
The RadioMaster ER8 is an 8-channel PWM receiver built on the ExpressLRS 2.4GHz protocol, designed for fixed-wing and multirotor applications requiring direct servo control. It features automatic voltage telemetry, a 4-pin CRSF port for sensor expansion, and supports Wi-Fi updates via a built-in WEBUI.
Features
- 8-Channel PWM output for direct servo and flight controller control.
- ExpressLRS 2.4GHz protocol for ultra-low latency and long-range performance.
- Automatic dual-source voltage telemetry (receiver or flight battery).
- Integrated 4-pin CRSF port for telemetry sensor expansion and configuration.
- One-piece molded shell and optimized PCB for high durability and reliability.

The RadioMaster ER8 receiver leverages the ExpressLRS ecosystem to deliver robust, low-latency control for fixed-wing aircraft and traditional multirotor setups. Its core design prioritizes integration simplicity, offering eight standard PWM outputs that interface directly with servos, flight controllers, or legacy autopilot systems without requiring a serial protocol converter.
Engineered for operational flexibility, the ER8 automatically detects and reports voltage from either its own power rail (4.5-8.4V) or an external flight battery (4.0-35V), providing critical telemetry data. The reserved CRSF port allows pilots to expand functionality with additional sensors. The compact, high-strength molded enclosure houses a dual-antenna design and supports adjustable output power up to 100mW for optimal link integrity.
