Open radio protocol for long range RC models
ExpressLRS
ExpressLRS is an open-source radio control link protocol for long range and low latency communication. It is used primarily in drones and aircraft. ExpressLRS uses LoRa, and FSK modulations on Semtech RF transceivers using an ESP32 or ESP8266 microcontroller. Since its release in 2018, ExpressLRS has been adopted in the FPV community for both hobbyist and commercial applications. It supports packet rates up to 1000 Hz on the 2.4 GHz frequency band and up to 1000 Hz on the 915/868 MHz bands while less frequent update rate settings enable ranges in excess of 100 km.
