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.
Key Features:
- 2.4GHz LoRa technology : Exceptional long-range communication and telemetry.
- CRSF protocol : Ensures seamless RC link integration.
- 5 power levels : Adjustable RF output ranging from 13dBm to a max 30dBm (1000mW).
- Fan-cooling system : Built-in 5V fan for optimal performance at higher output levels.
- Bluetooth compatibility : Integrated HC-04 module for easy setup and monitoring.
Specifications:
- Processor : STM32G431KB, running on mLRS firmware
- LoRa chip : SX1281 with TCXO for stable performance
- Amplifier : PA/LNA SKY68383-11
- Frequency : 2.4GHz ISM band
- RF Power Options : 13dBm, 20dBm, 24dBm, 27dBm, 30dBm (1000mW max)
- Antenna Connector : IPEX MHF-1 to SMA/RP-SMA
- Adapter Features : TX2 RC input (CRSF), DFU mode button, LEDs for mLRS and Bluetooth status
- Power Supply : 5-13V DC via JR_PIN3 (VIN)
Dip switch
- Dip switch 1/2/3 all ON, enable HC-04 communication with UART1 of STM32G431
- Dip switch 3 ON, 1 & 2 OFF, connect USB-TTL to G/3v3/BT-T/BT-R to configure HC04 via AT command
- Dip switch 1/2/3 all OFF, you can connect other Bluetooth or WiFi module to G/3v3/Rx1/Tx1
Firmware Flashing:
Download STM32CubeProgrammer from ST website
mLRS firmware:
- https://github.com/olliw42/mLRS/tree/v1.3/firmware/release-matek
- Targets: tx-matek-mr24-30-g431kb-default
————————————————————————————————————
Make sure STM DFU driver has been installed. Check out "Install DFU Drivers" in this page
Connect the TX module USB to computer while holding the boot button in.
- Select USB
- USB1 and click Refresh
- Connect
- select "Erasing & Programming"
- Tick all sectors and click "erase selected sectors"
- Browse firmware (hex or bin file) related to the hardware.
- Click "Start Programming"
- After programming, unplug USB and plug USB back in. If red LED blinks at 2Hz, the TX module is waiting for connecting with receiver.
Lua Script Configuration:
https://github.com/olliw42/mLRS/tree/main/lua
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:
- If your radio has a 480×272 color screen (e.g. Jumper T16, Radiomaster TX16S) then use the "mLRS.lua" file
- If your radio has a black and white screen (e.g. Frsky Taranis X9E, Radiomaster Zorro) then use the "mLRS-bw.lua" file
Note: The mLRS script requires EdgeTx version 2.9.x or later.
Setup
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.
- Note: mLRS only officially supports 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".
