GEPRC ELRS DUAL 915M / 868M Receiver for FPV Drone – True Diversity, 50mW, TCXO, 200Hz Refresh

Overview

The GEPRC ELRS DUAL 915M Diversity Receiver is a lightweight, high-efficiency receiver system designed for long-range FPV drone applications. Built upon the ExpressLRS open-source protocol, it supports a maximum refresh rate of 200Hz, delivering low latency, high reliability, and extended control range. The dual independent RF links and strategically placed antennas ensure strong signal reception and consistent link quality, especially in complex flight environments.

Equipped with a temperature-compensated crystal oscillator (TCXO), the receiver maintains frequency accuracy across temperature fluctuations. The built-in WiFi antenna allows easy OTA firmware updates, and installation is streamlined with a compact 18x25mm footprint and SH1.0 4-pin connector.
