Matek ELRS-R24-D 2.4GHz Nano Receiver

The Matek ELRS-R24-D is a diversity 2.4GHz ELRS receiver built to maintain a bulletproof RF link on long-range, freestyle and cinematic FPV drones. By utilising an onboard RF switch to actively select the strongest signal path between its dual antennas, this receiver mitigates dead zones and polarisation losses, ensuring your control link remains locked in even when flying behind concrete structures or dense foliage.

Key features

• Antenna diversity architecture actively handles signal multi-pathing to prevent failsafes in challenging RF environments.
• High 22.5dBm telemetry output easily punches flight data and sensor warnings back to your radio.
• Native WiFi integration allows for quick wireless firmware flashing and parameter configuration without USB access.
• Compact 21x15mm footprint fits cleanly inside crowded miniquad frames and fixed-wing bays.

Specifications

This receiver runs off any standard 5V pad on your flight controller and communicates via a standard UART. To make the most of the diversity hardware, mount the two included antennas perpendicularly (in an L-shape or V-shape) to maximise reception across all drone orientations.
