iRangeX iRX4 Multi Protocol Module

4-in-1 Multi-Protocol TX Module for FrSky 

This 4-in-1 transmitter module is designed for the FrSky Lite module bay and integrates four RF chips—CC2500, NRF24L01+, A7105, and CYRF6936—onto a single circuit board. It supports a wide range of popular RC protocols, including Futaba S-FHSS, Walkera DEVO, Spektrum DSM2/DSMX, FlySky, FrSky, WLToys, Hubsan, Hisky, Esky, Assan, and more.

With this module, you can flexibly control a variety of models using your favourite transmitter, greatly expanding your compatibility and flying options.

This module is fully compatible with the Multi-Module Project (available on GitHub) and is based on an ARM microcontroller. In serial mode, all supported protocols are accessible via your transmitter’s menu, with no hardware modifications required.

To use serial mode, simply update your transmitter’s firmware to the latest version. Model protocol selection, binding, and telemetry integration (where supported) are all handled directly through your transmitter’s Model Settings menu for a seamless experience.
