Compact RADIOMASTER ER8 2.4GHz ExpressLRS Receiver for RC Fixed-Wing Pilots

The RadioMaster ER series of PWM receivers are based on the revolutionary ExpressLRS system, offering high performance, high reliability, flexible configuration, fast response speed, and ultra-long range, providing users with a brand-new experience in their hobby. The ER8 receiver has been specially designed for fixed-wing aircraft, with the ability to drive up to 8 servos and built-in receiver voltage telemetry and flight battery telemetry, automatically detecting the voltage input to use. A 4-wire CRSF interface is provided to facilitate later expansion of telemetry sensors.

The ER8 receiver features a dual-antenna with telemetry power up to 100mW, and the receiver shell adopts a one-piece molding process with high structural strength. The product supports Wi-Fi updates and WEBUI configuration, ensuring easy and convenient firmware updates and configuration. Additionally, the ER8 receiver offers automatic voltage telemetry of the external battery voltage or built-in receiver voltage, providing users with comprehensive power monitoring capabilities.

The ER8 2.4GHz ELRS PWM Receiver is powered by DC 4.5 - 8.4V and utilizes a 20cm high-sensitivity antenna. It supports the ExpressLRS 3.3.0 pre-installed wireless protocol and provides 8-channel PWM output. The telemetry power of the receiver can be adjusted up to a maximum of 100mW, and the battery voltage detection range is DC 4.0 - 35V. The ER8 receiver weighs 16.5 grams and has dimensions of 433015mm.

The package includes the ER8 2.4GHz ELRS PWM Receiver, a voltage telemetry wire (Type-B), a CRSF wire, an ELRS-RX-SBUS wire, and a user card. The ER8 receiver is designed to provide users with a high-performance, reliable, and flexible control solution for their fixed-wing aircraft and other RC models.
