iFlight ELRS diversity receiver is a true dual-antenna diversity receiver developed in close cooperation with the ExpressLRS Team. ExpressLRS is known for its long-range operation, low latency, and high-power telemetry feedback capabilities.

The ELRS diversity receiver features well-placed dual antennas with shielding covers, enhancing its resistance to interference, widening signal reception, and ensuring a more stable connection compared to conventional single-antenna receiver systems.

It incorporates a TCXO temperature-compensated crystal oscillator to prevent frequency shifts caused by temperature variations. It significantly meets the reliability requirements for long-distance flights, aerial photography, or FPV freestyle maneuvers.

Note: If you want to use Gemini mode, you need to use a TX that supports Gemini mode.

Features:

SGemini mode and True Diversity mode are compatible, better reception effect
Integrated shields can protect electronic components and enhance anti-interference capabilities.
Newly upgraded Temperature Compensated Crystal Oscillator, lower packet loss, high-frequency stability
Up to power 250mW(2.4G) telemetry transmission, resulting in stronger telemetry signals and significantly reducing instances of telemetry loss.
High-performance at 2400MHz

Performance and Compability

Make sure to install the antenna away from conductive or magnetic components (carbon, metal, motors).

Flash the latest firmware and follow the ELRS Community for updates, tutorials or contributions.

Use iFlight ELRS receivers coupled with our transmitter for maximum performance! We've probably achieved market's best crystal frequency stability at a very low frequency deviation.
