RadioMaster ER6 6-Channel 2.4 GHz ELRS PWM Receiver

RadioMaster ER6 6-Channel 2.4 GHz ELRS PWM Receiver

Product description

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

With six PWM outputs, integrated voltage telemetry, and an additional CRSF interface, the ER6 is particularly well-suited for model-building applications that require flexible control and reliable monitoring of the power supply.

6 PWM channels with ExpressLRS 2.4 GHz

The RadioMaster ER6 allows for the direct connection of up to six servos. The ExpressLRS 2.4 GHz 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 ranging from 4 to 35 V. Automatic voltage detection simplifies configuration. The telemetry transmission power can be set to 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.

Built-in Wi-Fi allows for convenient firmware updates and settings adjustments via the WebUI. The rugged plastic housing protects the electronics and facilitates installation in various RC models.
