GEPRC ELRS Nano 2.4G PA100 Receiver for FPV Drone – 100mW, 1000Hz, TCXO, WiFi OTA, 0.7g

Overview

The GEPRC ELRS Nano 2.4G PA100 Receiver is a next-generation miniature receiver designed for high-performance FPV drone systems. Built on the ExpressLRS 2.4GHz protocol, it delivers ultra-fast response, long-range reliability, and telemetry power up to 100mW, all in a form factor weighing just 0.7g.

This receiver integrates both PA (Power Amplifier) and LNA (Low Noise Amplifier) to strengthen uplink and downlink communication. A TCXO (temperature-compensated crystal oscillator) ensures consistent signal locking under extreme conditions. With WiFi OTA support, firmware updates are quick and cable-free—ideal for minimal setups and micro builds.
