Description

The IronLink Rx-D ELRS receiver is engineered for demanding FPV racing, long-range exploration, and professional UAV applications where communication reliability is critical. Its advanced RF system and true antenna diversity continuously monitor and select the optimal antenna signal, significantly reducing packet loss and improving control stability in signal-challenged environments like urban areas or behind obstacles.

Powered by an ESP8285, the receiver supports the full feature set of the ExpressLRS protocol, including dynamic packet rates and model match. The integrated Wi-Fi access point allows pilots to connect directly to the receiver for firmware flashing and detailed parameter adjustment via a web browser, streamlining the setup and maintenance process. The unit operates on a standard 5V DC supply, making it compatible with most flight controller BEC outputs.

Key Features

  • True Antenna Diversity: Employs two independent 2.4GHz antennas with intelligent switching logic to maintain the strongest possible RF link, mitigating nulls and multipath interference.
  • High-Power Telemetry: Capable of transmitting telemetry data back to the transmitter at up to 100mW, ensuring a reliable data return path for long-distance flights and robust RSSI monitoring.
  • Integrated Wi-Fi Management: Features a built-in Wi-Fi module that creates a configuration access point, enabling wireless firmware updates and parameter tuning through the ExpressLRS WebUI.
  • Ultra-Low Latency Architecture: Leverages the efficiency of the ExpressLRS protocol and the ESP8285's processing power to deliver minimal control latency, essential for precise racing and acrobatic maneuvers.
  • Compact & Lightweight Design: With dimensions of 21x15x3.7mm and a weight of just 1.2g (excluding antennas), it adds negligible mass and size to any drone or fixed-wing aircraft build.
  • Wide Voltage Compatibility: Operates on a stable 5V input, typically supplied directly from a flight controller's BEC or a regulated PDB, simplifying integration into most multirotor and UAV power systems.

Applications

  • High-performance 5-inch FPV racing drones requiring the lowest possible latency and reliable control links.
  • Long-range 7-inch cinematic or exploration drones where extended telemetry range and signal redundancy are critical.
  • Fixed-wing UAVs and planes used for mapping, surveillance, or FPV cruising that benefit from a stable, long-distance control link.
  • Compact 3-inch and 4-inch freestyle builds where saving weight and space is paramount without sacrificing radio performance.
  • Professional UAV platforms integrating with ArduPilot or PX4 autopilots, needing a robust telemetry downlink for mission monitoring.

Frequently Asked Questions

What is the operating voltage for the EDITHFPV IronLink Rx-D receiver?

The IronLink Rx-D requires a stable 5V DC power supply. This is typically provided by connecting it to a 5V BEC output on your flight controller or power distribution board. Ensure your power source can deliver clean, regulated 5V to prevent brownouts or damage to the receiver's ESP8285 microcontroller.

How does the true antenna diversity system work?

The receiver features two independent antenna inputs and continuously monitors the signal strength (RSSI) on both. Its intelligent switching logic selects the antenna with the strongest, clearest signal in real-time. This process mitigates signal nulls, reduces packet loss caused by multipath interference, and significantly improves overall link stability, especially when flying in environments with obstacles.

Can I update the firmware without soldering or a dedicated module?

Yes. The receiver has a built-in Wi-Fi module. To update, power on the receiver, connect to its Wi-Fi access point from a computer or smartphone, and open the ExpressLRS WebUI in a browser. From there, you can flash new firmware and configure all settings wirelessly, eliminating the need for a physical serial connection or disassembling your drone.

What is the maximum telemetry output power, and why is it important?

The IronLink Rx-D can transmit telemetry back to your radio transmitter at up to 100mW. Higher telemetry power ensures a stronger return signal, which is crucial for maintaining a reliable data link (for RSSI, battery voltage, GPS coordinates) over long distances. This allows you to monitor your aircraft's status effectively even at the edge of your control range.
