IRX4 Lite 4 IN 1 Multiprotocol Tx Module for FrSky Radios

Compatible with Lite version external module bays (e.g., FrSky X-Lite).

This 4-in-1 TX module integrates four RF chips — CC2500, NRF24L01+, A7105, CYRF6936 — into one compact unit, supporting a wide array of RC protocols including Futaba S-FHSS, Walkera DEVO, Spektrum DSM2/DSMX, Flysky, FrSky, WLToys, Hubsan, Hisky, Esky, Assan, and more.

The IRX4 Lite is based on an ARM microcontroller and compatible with the Multi-module project on GitHub. It operates in serial mode, enabling model and protocol selection directly from your transmitter’s settings menu — no hardware mods required. Telemetry support is fully integrated with capable transmitters.
