The FrSky Multi Protocol Module is a 4-in-1 transmitter module that is compatible with FRSKY X-Lite. It combines four RF chips (CC2500, NRF24L01+, A7105, CYRF6936) into a single circuit board, enabling support for various remote control protocols such as Futaba S-FHSS, Walkera DEVO, Spektrum DSM2, DSMX, Flysky, Frsky, WLToys, Hubsan, Hisky, Esky, Assan, and others. This module offers flexibility in controlling your model, providing an exceptional experience with your preferred transmitter.
Moreover, this module works seamlessly with the Multi-module project on GitHub and is based on an ARM microcontroller. All available protocols are included in serial mode, which utilizes a serial protocol to communicate with your transmitter without the need for any hardware modifications. However, it is recommended to update your transmitter's firmware to the latest version before selecting and binding the model protocol from the Model Settings menu. For telemetry-capable transmitters, the integration of telemetry is effortless with the transmitter firmware.
The FrSky Multi Protocol Module operates at a voltage range of 5-9V, with an operating current of <=180mA, and operates at a frequency of 2.4G ISM band. It has a high RF power of +22dBm and is equipped with an ARM CORTEX-M(128K ROM, 20K RAM) MCU. The module weighs 32g and comes with 1 MPM LITE TX Module in the package.
