Description
mR900-22 900MHz LoRa Module with mLRS Firmware
The mR900-22 is a compact and efficient 900MHz LoRa module, designed for long-range communication in UAVs and remote control systems. Powered by the STM32WLE5CC with TCXO and running mLRS firmware, this module supports RF frequencies of 868MHz and 915MHz (FCC), making it versatile for various regional applications. It offers adjustable RF power outputs ranging from -9dBm to 22dBm (158mW), ensuring reliable connectivity even in challenging environments.
The module features bi-directional Serial MAVLink communication via TX2/RX2, and RC output options (CRSF or SBUS) via TX1. It is equipped with an IPEX MHF-1 antenna connector and comes with an 8cm dipole antenna. The mR900-22 is designed for ease of use with two buttons for boot mode and binding, making it simple to integrate into your UAV or remote control setup.
