【ExpressLRS】 ExpressLRS is an open-source RC link for RC applications, based on Semtech Lora SX127x or SX1280 hardware for RX and TX respectively. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.
【ExpressLRS Receiver】BETAFPV Nano receiver is based on the ExpressLRS project, an open-source RC link for RC applications which aims to achieve the best possible link performance in both speeds, latency, and range suit for ELRS TX module or Nano bay, etc.
【Crossfire Serial Protocol 】ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the receiver and the flight controller board. So make sure your flight controller board supports the CRSF serial protocol. How to set up the CRSF protocol can be viewed on the fourth page of the manual.
【Nano Size】This receiver only has 0.7 grams and the volume is 12mm*19mm which is very suitable for Tiny whoop because of the ultra light and Nano size.
【Configuration & Bind】 Nano receiver could enter binding status by power on/off three times. Step: Plugin and unplug nano receiver three times; Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode; Make sure the RF TX module or radio transmitter enter binding status, which sends out a binding pulse; If the receiver has a solid light, it’s bound.
