An STM32/ESP32/ESP8285-based radio link for RC applications #ESP32 #Radio #RC

ExpressLRS is an STM32/ESP32/ESP8285-based High-Performance Radio Link for RC applications

It is based on the fantastic semtech SX127x/SX1280 hardware combined with an ESP8285ESP32 or STM32. ExpressLRS supports a wide range of hardware platforms as well as both 900 MHz and 2.4 GHz frequency options. ExpressLRS uses LoRa modulation as well as reduced packet size to achieve best in class range and latency compared to current commercial offerings.

ExpressLRS can run at various packet rates, up to 500hz or down to 25hz depending on your preference of range or low latency. At 900 MHz a maximum of 200 Hz packet rate is supported. At 2.4 GHz a blistering 500 Hz is currently supported with a custom openTX binary with future plans to extend this to 1000 Hz.

ExpressLRS supports telemetry as optional feature. Enabling telemetry also adds support for the betaflight lua script.
