Matek mR900-30 is a module for mLRS system on the frequency of 868mhz. mLRS (mavlink long range system) is an opensource project that combines RC link with Mavlink telemetry in one. It is especially suitable for long range flights with classic drones or airplanes using Ardupilot or iNav firmware.
The Matek mR900-30 operates at 868 or 915MHz and the maximum transmit power is 1000mW (30dBm). The advantage of the mR900-30 is the available dual UARTs, where you can have Mavlink input/output and CRSF or SBUS input at the same time.
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.
A small heatsink is included.
