HGLRC ELRS 2.4G Receiver

A simple ExpressLRS receiver from HGLRC

The HGLRC ELRS 2.4G Receiver is a compact and efficient communication module for FPV drones and other remote-controlled devices. It runs on the reliable 2.4 GHz frequency and supports the ExpressLRS protocol for long-range connectivity with low latency.

Hardware is straightforward: an ESP8285 microcontroller and an SX1280 RF module, with an omni-directional antenna, powered from 5 V. It supports telemetry, so real-time data goes back to the controller.

Installation advice

The receiver is light enough that it does not noticeably add to the weight of a quad. Solder it to a flight controller UART for a CRSF connection, bind it to your ExpressLRS transmitter with a shared binding phrase, and check that the firmware version matches your radio's ExpressLRS version. Place the antenna where it sees clear air, away from carbon fibre and power wiring.

The maker does not publish size or weight on the product page, so check the physical unit against your available space.

Who it is for

Pilots who want a low-cost ExpressLRS receiver for a quad or a small aircraft. For long-range or diversity needs, choose a receiver with two antennas.

Checking before you fly

After soldering, confirm that the receiver shows up in your flight controller's receiver tab and that channels move when you move the sticks. Set the failsafe to something safe such as a disarm or a controlled descent, and run a short range test with reduced transmitter power. If your radio has been updated to a newer ExpressLRS release, update the receiver to match.
