ExpressLRS ELRS 500mW Receiver
A new version of the iFlight ELRS Receiver is available. It incorporates a temperature-compensated crystal oscillator to prevent frequency shifts caused by temperature variations, with telemetry power reaching up to 500mW. It significantly meets the reliability requirements for long-distance flights, aerial photography, or FPV freestyle maneuvers.
Single-sided electronic components, saving assembly space
Aluminum heatsink plate to protect electronic components, and enhance anti-interference capability
Newly upgraded Temperature Compensated Crystal Oscillator, lower packet loss, high frequency stability
Pre-soldered SH1.0 connector (Plug&Play for easy installation with iFlight FCs)
Up to power 500mW telemetry power, resulting in stronger telemetry signals and significantly reducing instances of telemetry loss.
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 https://github.com/ExpressLRS/ExpressLRS/wiki/Crystal-Oscillator-(XO)-Frequency-Error
The 900MHz as well as 2400MHz band have outstanding performance and long range capabilities. If you're not sure what to get, please checkout the official ELRS Long Range Competition to see what has been achieved. https://www.expresslrs.org/2.0/info/long-range/
What can you expect? Due to local regulations, the 900MHz FCC region seems to have a better performance than the 868MHz EU region. The 2400MHz band works great in any region, has a higher packet rate up to 500hz. This is not a common 2400MHz protocol and cannot be compared to anything prior on the market.

Telemetry Power are different ：ELRS 500mW RX has high power telemetry.
The Telemetry Power of ExpressLRS Nano RX is (50mW 868/900MHz) / （17mW 2.4G），while the ELRS 500mW RX has 500mW telemetry power, with strong signal reception and anti-interference capabilities

Differences: ELRS Diversity RX supports Gemini and True Diversity modes, with better anti-interference effect and better signal reception effect
For iFlight ELRS Diversity RX: If you need to use Gemini, you need to use a TX that supports Gemini mode at the same time.
Note: iFlight ELRS 2.4GHz Diversity RX only has 250mW power

1.ExpressLRS ELRS Nano RX :Smaller size, lighter and easier to install, with TCXO: adapts to drones below 5 inches: especially suitable for freestyle drones
2. iFlight 500mW RX : Are compatible with all drones，equipped with TCXO and 500mW telemetry power, with strong signal reception and anti-interference capabilities
3. iFlight ELRS Diversity RX : With TCXO, adapts to drones above 5 inches, especially suitable for long range drones : supports Gemini and True Diversity modes with better anti-interference effect and better signal reception effect . If you need to use Gemini, you need to use a TX that supports Gemini mode at the same time.
