Matek mR900-30-TX is a transmitter module for the mLRS system at the frequency of
The mR900-30 operates at 868 or 915MHz and the maximum transmit power is 1000mW(30dBm). The advantage of the mR900-30 is the available two UARTs, where you can have a Mavlink output and a CRSF or SBUS output at the same time.
The TX kit includes the mR900-30 module and the mRx-TX adapter. The kit adds Bluetooth for easy connection to a PC, a fan for active cooling, easy compatibility with the JR shaft, LEDs for indication, and the ability to power in the 5-13V range.
The SX1262 LoRa chip with TCXO is used for transmitting. The SX1262 chips are not compatible with the older SX127x LoRa chips used on ELRS hardware.
The transmit module does not include a box. 3D printing models are available for download here.
