Description: ExpressLRS is an opensource RC link for RC applications. Everyone could find this project on Githubs or join the discussion in Facebook Group. ExpressLRS is based on Semtechs Lora SX127x or SX1280 hardware for RX and TX respectively. it aims to achieve the best possible link performance in both speeds, latency, and range. At 900 MHz a maximum of 200 Hz packet rate is supported. At 2.4 GHz a blistering 500Hz is currently supported with a custom OpenTX build. This makes ExpressLRS one of the fastest RC links available while still offering performance. More and more vendors start to support the ExpressLRS radio protocol in different parts, like radio transmitter with ELRS in stock, drone with builtin ELRS receiver, ELRS TX module for JR bay, or Nano bay. BETAFPV team take part in this project and provide a series of ExpressLRS components. ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the receiver and the controller bo
