Description

The HGLRC ELRS 915MHz Receiver is engineered for pilots who demand maximum control range and signal reliability. By operating on the 915MHz frequency band, it leverages longer wavelengths that diffract more effectively around obstacles, providing a more stable link in environments with dense foliage or urban structures. This makes it a superior choice for long-range exploration, mapping, and FPV flights where maintaining a control link is critical.

Based on the ExpressLRS open-source ecosystem, this receiver offers exceptionally low latency and high refresh rates, ensuring precise and responsive control even at distances exceeding 10 kilometers. The integrated SX1276 LoRa chipset handles the physical layer communication with high sensitivity and interference resistance. Its compact footprint and minimal weight allow for integration into a wide variety of multirotor and fixed-wing UAVs without compromising flight performance.

Key Features

  • 915MHz Long-Range Band: Utilizes the 915MHz ISM band for enhanced signal penetration through obstacles and extended operational range, ideal for beyond-visual-line-of-sight (BVLOS) applications.
  • ExpressLRS CRSF Protocol: Implements the Crossfire Serial Protocol (CRSF) over the high-performance ExpressLRS firmware, enabling sub-10ms latency and high update rates for precise control.
  • SX1276 LoRa Chipset: Features the reliable SX1276 transceiver, known for its excellent receiver sensitivity and robust communication in noisy RF environments.
  • Dual Connection Options: Supports both direct plug-in connection via the included 4-pin cable and solder pad access for permanent, clean installations.
  • Wide Voltage Input: Accepts 3.3V to 5V DC, making it compatible with both 3.3V serial pads on modern flight controllers and standard 5V BEC outputs.
  • Ultra-Compact & Lightweight: Measures just 21mm x 11mm and weighs only 0.9 grams (without antenna), minimizing impact on drone weight and balance.

Applications

  • Long-Range FPV Exploration Drones requiring stable control links over several kilometers.
  • Fixed-Wing UAVs and Planes used for mapping, surveying, or autonomous missions beyond visual line of sight.
  • Heavy-Lift Cinematography Drones where reliable control is paramount, especially in complex RF environments.
  • Mini-Long-Range Builds where the compact size and light weight are critical for endurance.
  • DIY Drone Projects utilizing ExpressLRS-capable transmitters like RadioMaster, HappyModel, or Jumper modules.

Frequently Asked Questions

What is the main advantage of a 915MHz receiver over a 2.4GHz receiver?

The primary advantage is significantly greater range and superior signal penetration through obstacles like trees and buildings. The 915MHz wavelength is longer than 2.4GHz, allowing it to diffract more effectively, resulting in a more stable and reliable control link for long-distance FPV and BVLOS flights.

Is this receiver compatible with my 2.4GHz ExpressLRS transmitter?

No, it is not directly compatible. This receiver operates on the 915MHz frequency band. To use it, you must have a transmitter or external module that also operates on 915MHz and is running compatible ExpressLRS firmware. Mixing 2.4GHz and 915MHz hardware will not work.

How do I power and connect this receiver to my flight controller?

The receiver accepts 3.3V to 5V input, which can be supplied from a dedicated 5V BEC or the 3.3V serial pad on most flight controllers. Connect the receiver's signal wire (typically the 'TX' pad on the receiver) to an unused UART 'RX' pad on your FC. Then configure the corresponding UART for Serial RX and set the protocol to CRSF in Betaflight or similar firmware.

Can I update the ExpressLRS firmware on this receiver?

Yes, as an ExpressLRS device, it is fully capable of being updated via the ExpressLRS Configurator. You will need a suitable USB serial flasher (like a HappyModel EP1 or EP2) to connect to the receiver's bootloader pins for firmware updates to newer ELRS versions.
