<p>The RadioMaster ER series of PWM receivers are based on the revolutionary ExpressLRS system. It offers high performance, high reliability, flexible configuration, fast response speed and ultra-long range bringing you brand new experience with your hobby.</p><p><br></p><p>The Radiomaster ER8 receiver has been specially designed for fixed-wing users. It can drive 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. A 4-wire CRSF interface is provided to facilitate later expansion of telemetry sensors. The ER8 features a dual-antenna with telemetry power up to 100mw. The receiver shell adopts one-piece molding process with high structural strength.</p><p><br></p><h4><b><br></b></h4><h4>Features</h4><h4><br></h4><p><span style="font-weight: normal;">Based on the Revolutionary ExpressLRS System</span></p><p><span style="font-weight: normal;">High performance, high reliability, flexible configuration, fast response speed and ultra-long range</span></p><p><span style="font-weight: normal;">Support 8 PWM Channels</span></p><p><span style="font-weight: normal;">Optimized ground up PCB design</span></p><p><span style="font-weight: normal;">Automatically voltage telemetry of external battery voltage or built-in receiver voltage</span></p><p><span style="font-weight: normal;">Supports Wi-Fi updates and WEBUI configuration</span></p><p><span style="font-weight: normal;">High quality 2.54 mm connector</span></p><p><span style="font-weight: normal;">Standard 20 cm High Sensitivity Antenna</span></p><p><span style="font-weight: normal;">Reserve 4pin CRSF input port</span></p><p><span style="font-weight: normal;">Shell adopts one-piece molding process with high structural strength</span></p><p><span style="font-weight: normal;">For fixed-wing aircraft and more</span></p><p><br></p><p><br></p><p><br></p><p><br></p>
