About

ExpressLRS is an open source Radio Link for Radio Control applications. Designed to be the best FPV Racing link, it is based on the fantastic Semtech SX127x/SX1280 LoRa hardware combined with an Espressif or STM32 Processor. Using LoRa modulation as well as reduced packet size it achieves best in class range and latency. It achieves this using a highly optimized over-the-air packet structure, giving simultaneous range and latency advantages. It supports both 900 MHz and 2.4 GHz links, each with their own benefits. 900 MHz supports a maximum of 200 Hz packet rate, with higher penetration. 2.4 GHz supports a blistering fast 500 Hz on EdgeTX. With over 60 different hardware targets and 13 hardware manufacuturers, the choice of hardware is ever growing, with different hardware suited to different requirements.

Configurator

To configure your ExpressLRS hardware, the ExpressLRS Configurator can be used, which is found here:
