Expand the versatility of your compatible FrSky transmitter with this 4-in-1 multiprotocol TX module for radios equipped with a Lite external module bay. The module combines four RF chips — CC2500, NRF24L01+, A7105 and CYRF6936 — into a single compact unit, providing support for a wide range of 2.4GHz radio-control protocols.

Compatible with the Multi-module project, the module uses an ARM microcontroller and supports available protocols through serial mode. Model protocol selection and binding can be managed directly through the transmitter's Model Settings menu when the transmitter firmware supports the module. Telemetry integration is also supported on compatible telemetry-capable transmitters.

Supported protocol families include Futaba S-FHSS, Walkera DEVO, Spektrum DSM2/DSMX, Flysky, FrSky, WLToys, Hubsan, HiSky, Esky and Assan, giving pilots the flexibility to operate a wide range of compatible models from one transmitter.

Important Notice
Before using this module with a FrSky ETHOS radio, download the required LUA script and place it in the appropriate Scripts folder on the transmitter's SD card. The transmitter firmware should also be updated to the latest available version where required.
