RadioMaster ER8 ELRS PWM Receiver (2.4ghz)

The RadioMaster ER series of PWM receivers leverage the revolutionary ExpressLRS system. They provide outstanding performance, high reliability, and flexible configuration. With a fast response and an ultra - long range, they bring a whole new level of enjoyment to your hobby. The Radiomaster ER8 is specifically designed for fixed - wing users. It can operate up to 8 servos and comes with built - in receiver voltage and flight battery telemetry, automatically detecting the appropriate voltage input. A 4 - wire CRSF interface is available for easy expansion of telemetry sensors later on. The ER8 features a dual - antenna design with a telemetry power of up to 100mw. Its shell is made through a one - piece molding process, ensuring high structural strength.

Using the RadioMaster ER8 ELRS PWM Receiver is quite straightforward. First, make sure the power supply is within the DC 4.5 - 8.4V range. Connect the receiver to your fixed - wing aircraft according to the included wiring diagrams. You can connect up to 8 servos to control your aircraft's movement. For telemetry, use the provided voltage telemetry wire and CRSF wire. When it comes to updates, you can use Wi - Fi to update the firmware and configure it through the WEBUI. Here are some things to keep in mind. Avoid exposing the receiver to extreme temperatures or moisture, as this can damage it. Also, check the battery voltage regularly, as the detection range is DC 4.0 - 35V. For maintenance, keep the receiver clean and free of dust. If you notice any performance issues, check the connections first. If problems persist, refer to the user card or contact customer support.
