HGLRC ELRS 2.4G Receiver

Buy the HGLRC ELRS 2.4G receiver for ultra-long and reliable communication with your FPV drone

The HGLRC brand (HGLRC Company) specializes in developing high-quality FPV components for racing and freestyle drones. The company actively collaborates with professional pilots to create products that precisely meet market needs. The HGLRC product range includes flight controllers, governors, motors, frames, and receivers based on the advanced open protocol ExpressLRS (ELRS).

HGLRC ELRS 2.4 GHz receivers are designed with a sophisticated design, minimal weight, and support the most advanced protocol features: ultra-long range, low latency, and high update rates.

5 main advantages of receivers

• Ultra-lightweight and compact — models weigh from 0.6 to 1.36 grams. This is ideal for micro drones and racing quadcopters.
• High refresh rate up to 1000 Hz - instant response to pilot commands for racing and freestyle flights.
• True Diversity and Gemini Technology — two radio modules and two antennas ensure maximum signal stability even with difficult orientation of the drone.
• Temperature compensation (TCXO) — stable operation at a frequency of 2.4 GHz at any temperature changes.
• Easy installation and update — connection via a connector or contact pads. Firmware updates via Betaflight Passthrough or Wi-Fi.

How HGLRC ELRS 2.4G receivers work

The receiver receives a signal from the transmitter (ELRS module) at a frequency of 2.4 GHz and transmits commands to the flight controller using the CRSF protocol. Built-in microcontroller (ESP8285, ESP32) processes the signal with minimal latency. LoRa modulation technology provides noise immunity and high range. Gemini-enabled models use two radios and two diversity antennas for maximum reliability.

The receiver transmits telemetry (signal level, voltage) back to the remote control. Installation is done by connecting to 5 V and GND, as well as to the UART port of the flight controller. Communication with the transmitter is carried out via factory firmware 3.x or higher.
