TBS Crossfire Diversity Nano RX

The TBS Crossfire Diversity Nano RX is a full-range, true diversity receiver designed for long-range FPV, fixed-wing builds, and cinelifters where control link redundancy is critical. By utilising two independent RF stages, the hardware actively evaluates and switches between two antennas to provide the most robust 868/915MHz link possible, preventing micro-failsafes caused by antenna polarisation or physical carbon-fibre shadowing.

Key features

• True dual-antenna diversity for maximum signal penetration and hardware redundancy.
• High-power telemetry output (up to 500mW) ensures reliable GPS and link data transmission at extended ranges.
• Integrated 1S LiPo charging circuit supports an external backup battery for the TBS Beacon mode, allowing you to locate downed aircraft.
• Supports standard CRSF serial for flight controllers or up to 8 channels of PWM via adapter boards.

Specifications

• Weight: 1.8g (receiver only)
• Dimensions: 24 x 14 mm
• Input voltage: 3.3V to 8.4V
• Antenna connectors: 2x U.FL (IPEX1)
• Telemetry power: Up to 500mW
• Firmware requirement: TBS Crossfire V2.87 or newer

To fully exploit the dual RF stages, mount your two antennas at 90-degree angles to each other, ensuring they have clear lines of sight away from the frame's carbon plates.
