GEPRC ELRS Dual 2.4GHz Diversity Receiver

The GEPRC ELRS Dual 2.4GHz is a true diversity receiver designed for mid-to-long-range freestyle builds, macroquads, and cinelifters where signal shadowing is a critical concern. Unlike single-RF receivers that merely switch antennas, this unit features two independent RF chips processing incoming signals simultaneously. This true diversity architecture dynamically relies on the strongest signal path, minimising packet loss when flying behind concrete, dense foliage, or your drone's own carbon frame.

Key features

• True diversity architecture with two independent SX1281 RF chips processing data in parallel.

• ESP32 microcontroller allows for straightforward Wi-Fi firmware flashing and binding.

• Nano form factor fits easily into tight freestyle frames or heavy-lift stacks.

• Outputs up to 100mW telemetry power for a robust data downlink on extended flights.

To maximise the benefits of the dual-RF design, mount the two required antennas perpendicularly (at a 90-degree angle to one another) to ensure optimal reception regardless of the drone's orientation in flight.
