RadioMaster ER6 2.4GHz ELRS 6CH PWM Receiver

The RadioMaster ER6 is a dedicated 6-channel PWM receiver built around the ExpressLRS protocol, tailored for fixed-wing aircraft, surface vehicles, and custom builds requiring direct servo control. It delivers the ultra-low latency and immense range of 2.4GHz ELRS without needing a dedicated flight controller to translate signals.

Key features

• Direct PWM Output: Provides 6 native PWM channels to drive servos and ESCs directly.

• Built-In Telemetry: Offers up to 100mW of return telemetry power, including integrated receiver voltage monitoring.

• External Voltage Sensing: Includes an EXT-V telemetry port to monitor the flight battery voltage up to 35V (suitable for up to 8S LiPo packs).

• Wide Voltage Input: Operates efficiently between 4.5V and 8.4V, natively supporting high-voltage (HV) servos without external BEC step-downs.

• Dual Antennas: Twin 20cm high-sensitivity antennas ensure a robust link across challenging line-of-sight and long-range flights.
