RadioMaster PWM ER8 2.4 GHz ELRS receiver

RadioMaster PWM ER8 2.4 GHz ELRS receiver

The RadioMaster ER series of PWM receivers is based on the revolutionary ExpressLRS system. It offers high performance, high reliability, flexible configuration, fast response and very long range, providing a completely new experience in your hobby.

The Radiomaster ER8 receiver has been specially designed for fixed-wing aircraft users. It can support up to 8 servos and has built-in receiver voltage telemetry and flight battery telemetry with the ability to automatically detect which voltage input to use. To facilitate subsequent expansion of telemetry sensors, a 4-wire CRSF interface is provided. ER8 is equipped with a dual antenna with telemetry power of up to 100 mW. The receiver housing adopts one-piece molding process with high structural strength.
