iFlight ExpressLRS ELRS 900MHz True Diversity Receiver

Description

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.

Features:

• Gemini 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 500mW(868MHz/900MHz)/250mW(2.4G) telemetry transmission, resulting in stronger telemetry signals and significantly reducing instances of telemetry loss.
• High-performance at 2400MHz or 900MHz (900 / 868 bands available)

Note:

• Gemini mode requires a TX that supports Gemini mode.
• 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. Please checkout this article for further information
