RadioMaster ER6 6-Channel 2.4GHz ELRS PWM Receiver

Product description

The RadioMaster ER6 is a powerful 6-channel ExpressLRS 2.4GHz PWM receiver for RC airplanes, gliders, and other RC models. Thanks to modern ELRS radio technology, dual antenna reception, and low latency, it offers a reliable control connection with a long range.

With six PWM outputs, integrated voltage telemetry and an additional CRSF interface, the ER6 is particularly suitable for model building applications where flexible control and reliable monitoring of the power supply are required.

6 PWM channels with ExpressLRS 2.4GHz

The RadioMaster ER6 allows the direct connection of up to six servos. The ExpressLRS 2.4GHz radio protocol ensures fast response times and stable signal transmission. The dual-antenna system improves reception reliability even when the model's orientation changes.

Integrated voltage telemetry

The receiver supports monitoring of the receiver voltage as well as an external flight battery voltage from 4 to 35 V. Automatic voltage detection simplifies configuration. The telemetry transmission power can be set up to 100 mW.

Flexible connections and easy configuration

In addition to the six PWM outputs, the ER6 offers a 4-pin CRSF interface for expansion with compatible telemetry sensors. CRSF and SBUS signal output are also supported.

Firmware updates and settings can be conveniently performed via the web interface using integrated Wi-Fi. The robust plastic housing protects the electronics and facilitates installation in various RC models.
