Take your telemetry game to the next level with the Matek mLRS 2.4GHz TX Module Kit. Designed for long-range communication, this JR-compatible TX module is tailor-made for the mLRS system, which offers a focus on telemetry—unlike its close cousin, ELRS. Powered by LoRa technology and the reliable CRSF protocol, this transmitter operates on the 2.4GHz ISM band and offers rock-solid connectivity over vast distances. Plus, with RF power that maxes out at a whopping 1000mW (30dBm), you're all set for long-range flying sessions without a hitch.
Equipped with a built-in 5V fan that kicks in when your output power hits 500mW or more, the Matek mLRS TX Module ensures your gear stays cool when the action heats up. While the 3D-printable JR case isn't included, you can either print one yourself using the files on Matek's website or let us do the heavy lifting with our custom 3D print service.

The mLRS Lua script provides the most convenient way to change the Tx and Rx module's settings.
The Lua script works on both OpenTx and EdgeTx radios but there are two different versions depending on the display of your radio:
Note: The mLRS script requires EdgeTx version 2.9.x or later.
Three things need to be done in order to use the Lua script:
The Tx module must be configured for CRSF or mBridge mode, by setting the parameter "Tx Ch Source" to "crsf" or "mbridge" respectively. Since firmware version v0.2.13 "crsf" is the default setting, so this will be already completed after an initial flash. If not, the CLI needs to be used to set this parameter accordingly, as described in CLI Commands .
In EdgeTX/OpenTX, navigate to MDL->MODEL SETUP and configure the external RF module for CRSF or mBridge protocol with 400K baud rate.
The Lua script "mLRS.lua" or "mLRS-bw.lua" located in the "lua" folder of the repository needs to be copied to the "SCRIPTS/TOOLS" folder of the radio's SD card. One can follow the common tutorials for how to do this.
You should then be able to run the Lua script by going to SYS->TOOLS on the radio, and selecting "mLRS Configurator".
Note : No SMA antenna or 3D printed case is included. Accessories may vary depending on stock availability.
