Product overview
The iFlight ExpressLRS ELRS 500mW Receiver is a single-antenna receiver for long-distance flights, aerial photography and FPV freestyle maneuvers. Built around an ESP 8285 MCU, it uses the CRSF protocol and offers 868MHz EU/900MHz FCC and 2.4GHz ISM versions. Telemetry output ranges from 100-500mW (20-27dBm) for the 868/900MHz version and 50-500mW (17-27dBm) for the 2.4G version. The 2400MHz band supports a packet rate up to 500hz. A temperature-compensated crystal oscillator helps maintain frequency stability as temperatures change.
Single-sided electronic components conserve assembly space, while an aluminum heatsink plate protects the electronics and enhances interference resistance. The receiver measures 14*25*4.3mm and weighs 1.8g. A pre-soldered SH1.0 connector provides plug-and-play installation with iFlight flight controllers. The 2.4G version includes LNA functionality; the 868/900MHz version does not support it. Install the antenna away from conductive or magnetic components such as carbon, metal and motors. Each package supplies one ExpressLRS 500mW Receiver and one antenna.
