iFligh ExpressLRS ELRS 500mW Receiver

The new version of the iFlight ELRS receiver is now available. It features a temperature-compensated crystal oscillator that prevents frequency drift due to temperature changes, and telemetry power reaches 500 mW. This greatly improves reliability for long-distance flights, aerial photography or freestyle FPV.

Features

Single-sided placement of electronic components, saving installation space

Aluminum heatsink plate to protect electronics and improve noise immunity.

Updated temperature compensated crystal oscillator, reduced packet loss, high frequency stability

Pre-soldered SH1.0 connector (Plug&Play for easy connection to iFlight FC)

Telemetry power up to 500 mW ensures a stable signal and significantly reduces communication losses.

Performance and Compatibility

Install the antenna away from leading or magnetic elements (carbon, metal, motors).

Update your firmware to the latest version and follow the ELRS Community for updates, instructions, or development contributions.

Use iFlight ELRS receivers with iFlight transmitters for maximum performance. They have one of the best frequency stability on the market.

Frequency options

The 900 MHz and 2400 MHz bands provide excellent performance and range. If you're unsure about your choice, check out the official ELRS Long Range tests.

Due to local regulations, the 900 MHz band in the FCC region shows better performance than the 868 MHz band in the EU. The 2400 MHz frequency is suitable for any region and has a higher refresh rate (up to 500 Hz). This is not an ordinary 2.4 GHz protocol and cannot be compared with other analogues on the market.
