The mLRS project offers an open-source, high-performance radio system based on LoRa technology, operating at 2.4 GHz, 915/868 MHz, and 433 MHz/70 cm, designed to deliver a secure, reliable, and robust link under any conditions.
While designed initially with MAVLink optimization in mind, mLRS always provides a transparent serial link, making it suitable for a wide range of applications. Its design ensures the strongest possible signal integrity while maintaining a relatively high data rate, balancing performance and reliability without compromise.
Radiomaster is proud to be an EdgeTX Gold Partner and to have played a pivotal role in the inception of the EdgeTX project. Our commitment goes far beyond just producing radios that run on EdgeTX; we are actively collaborating with the EdgeTX team to drive innovation and help shape the future of EdgeTX based technology.
