iFlight Dualband Diversity is an advanced ELRS receiver supporting the Xrossband mode. The receiver contains two Semtech LR1121 chips, each capable of operating on 2.4GHz or 868/915MHz. You can run the receiver in Gemini mode at either 2.4GHz or 915MHz, or in XROSSBAND mode where one chip receives at 2.4GHz and the other at 868/915MHz (transmitter module must also support this feature). This setup provides excellent interference resistance. It is also compatible with standard ELRS transmitters operating on a single band.
