Description

This open-source diversity receiver leverages two independent RX5808 modules to continuously monitor and select the strongest signal from two connected antennas, such as a cloverleaf for omnidirectional coverage and a patch antenna for directional gain. The automatic switching algorithm requires no user intervention, ensuring a stable video feed during high-speed maneuvers or long-range excursions.

The built-in OLED display provides critical telemetry, including active channel, signal strength (RSSI), and diversity state, allowing for on-the-fly configuration and monitoring. Its design is based on fully open-source hardware and firmware, enabling advanced users to customize functionality and data display to suit specific FPV applications, from competitive racing to cinematic aerial photography.

Key Features

  • Dual-Module Diversity: Two RX5808 receivers with automatic signal selection eliminate dropouts and provide a cleaner video feed.
  • Integrated OLED Interface: Real-time display of channel, RSSI, and system status for immediate situational awareness.
  • Full 5.8GHz Band Coverage: Supports 40 channels across the 5705–5945 MHz spectrum for global FPV band compatibility.
  • Open-Source Platform: Hardware and firmware are open for community development and custom feature implementation.
  • Low-Voltage Operation: Wide 3.5V–5.5V input range allows for flexible powering from USB, BEC, or LiPo sources.
  • Compact & Lightweight: Measures 79mm x 40mm x 10mm and weighs 37g for easy integration into portable ground stations.
  • Direct AV Output: Provides standard analog composite video and audio signals for direct connection to displays or recording devices.

Applications

  • Ground station upgrade for Fat Shark Dominator, HDO, or other analog FPV goggles.
  • High-speed 5-inch FPV racing quadcopters requiring robust, dropout-free video links.
  • Long-range freestyle or aerial photography drones utilizing directional and omnidirectional antenna pairs.
  • Portable field monitor setup for drone pilots and spotters.
  • DIY FPV projects and educational platforms for learning RF and diversity reception principles.

Frequently Asked Questions

What is the primary advantage of a diversity receiver like the RX5808 Pro?

The primary advantage is significantly improved signal reliability and reduced video dropouts. By using two independent receivers connected to different antenna types (e.g., one omnidirectional and one directional), the system automatically and seamlessly switches to the antenna with the strongest signal in real-time. This is crucial for maintaining a clear video link when flying behind obstacles or at the edge of your transmitter's range.

Can I install this module directly into my Fat Shark goggles?

Yes, this module is designed as a direct replacement or upgrade for the standard receiver module bay in Fat Shark Dominator and similar goggle models. The included right-angle Burg connector and compact dimensions allow for a straightforward installation. It provides a significant upgrade over single-antenna modules by adding automatic diversity reception.

What power source do I need, and how do I connect it?

The receiver operates on a wide voltage range of 3.5V to 5.5V DC. You can power it directly from a 1S LiPo battery, a regulated 5V BEC from your ground station, or even a USB power bank using the provided Dupont cable. Connect the red wire to positive (3.5-5.5V), the black wire to ground, and the yellow wire typically carries the analog video output signal to your display or goggles.

Does the OLED screen show signal strength (RSSI)?

Yes, the integrated OLED screen displays real-time information including the active channel, the currently selected receiver module (A or B), and a relative RSSI (Received Signal Strength Indicator) value for each antenna. This allows you to visually monitor your link quality and see the diversity system in action as it switches between antennas based on signal strength.

Package Includes

  • 1 x RX5808 Pro Diversity Receiver Module (with pre-installed OLED)
  • 1 x Dupont Cable (for power and signal)
