Product details
The iFlight ELRS Dualband Receiver (ELRS) Receiver redefines reliability with its dualband technology, supporting 2.4GHz, 868MHz, and 900MHz frequencies. Featuring a temperature-compensated crystal oscillator (TCXO), it ensures stable performance in any environment. Choose between single or dual-antenna configurations for enhanced compatibility and signal strength. Perfect for long-range flights, aerial photography, and FPV freestyle, this receiver delivers unmatched precision and reliability for all your flying needs. Elevate your experience with iFlight.
Features
TCXO Technology: Minimizes frequency deviation for precise and stable performance.
Multi-Frequency Support: Compatible with 2.4GHz, 868MHz, and 900MHz for versatile use.
Compact Design: Space-saving and lightweight for easy integration.
100mW Dualband Receiver Only:
Ultra-Lightweight: Weighs only 0.5g, saving space and reducing aircraft weight.
SUR 0.8 Connector: Simplifies installation and setup.
500mW Dualband Receiver Only:
Single-Sided Components: Optimizes space efficiency.
Aluminum Heat Sink: Protects electronics and enhances interference resistance.
SH1.0 Connector: Easy installation with robust connectivity.
High-Power Telemetry: Supports 500mW telemetry return for stronger signals and reduced telemetry loss.
100mW Dualband Diversity Receiver Only:
Advanced Diversity Modes: Supports GemX, Gemini, and True Diversity RF modes for superior interference resistance and reception (Note: To use GemX, a high-frequency transmitter module that supports GemX mode is required).
Shielded Design: Protects electronics and improves interference resistance.
SH1.0 Connector: Ensures easy and reliable installation.
Performance and Compatibility
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.
Band Option
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.
