📝 ELRS Receiver 433 MHz (150–700 MHz) + 2.4 GHz (1.7–2.7 GHz) LR1121 True Diversity Generic ESP32C3 Aeronetix

The Aeronetix ELRS True Diversity receiver based on ESP32C3 and dual LR1121 transceivers is designed for UAV control systems using the ExpressLRS protocol. The receiver operates in 150–700 MHz and 1.7–2.7 GHz bands and features True Diversity with two independent LR1121 transceivers, significantly improving signal stability and link range. It is a modified analogue of the Radiomaster XR4 and can be flashed with Generic_C3_Gemini_LR1121_RX firmware. Tested with MilELRS, modified ELRS and Barvinok-5 firmware.

🫡 We are a team of veterans

From ELRS operational experience, True Diversity systems are significantly more stable than standard receivers because they use two antennas and two receiving paths. The receiver automatically selects the best signal or works with both channels simultaneously. This significantly reduces signal loss, especially at long distances or when flying behind obstacles.

💬 Comment / comments

The receiver is built on dual LR1121 transceivers enabling True Diversity operation. It can operate with two antennas simultaneously, significantly improving signal stability and range. Supports low-frequency operation for long range and 2.4 GHz for higher data rates. Base frequency is configured during firmware flashing.

🎯 Who it is suitable for

Military units, UAV operators and ELRS system users, who require long-range control links with maximum signal stability. True Diversity significantly reduces signal loss risk, especially at long range or behind obstacles.

FPV drone operators, who use ExpressLRS and need maximum link stability. The receiver can operate across multiple frequency bands. It is a universal solution for different drone types.

Engineers and UAV system developers, building control systems or repeaters. The receiver supports different firmware and configurations. It can be used in complex communication systems.

Teams developing repeater or communication systems, for building stable UAV control links. True Diversity allows more stable operation in difficult communication environments.
