Know More About ExpressLRS

ExpressLRS is an open-source RC link for RC applications. Everyone could find this project on Github or join the discussion inFacebook Group.

ExpressLRS is based on Semtech 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 long-range performance.

More and more vendors start to support the ExpressLRS radio protocol in different parts, like radio transmitter with ELRS in stock, drone with built-in 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.

Welcome to ExpressLRSI The best RC link that you can build yourself

Configuration & Bind 

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. Next, we use the flight controller with Betaflight firmware to show how to set up the CRSF protocol.

The connection between the ELRS Nano receiver and the FC board is shown below.

make sure that the LED flashes quickly twice, indicating that the receiver is in binding

Enable the corresponding UART (e.g. UART3 below) as a Serial Rx on Betaflight Configurator “Ports” tab.

Identifier Configuration/MSP Serial Rx USB VCP 115200 UART

On the “Configuration” tab, select “Serial-based receiver” on the “Receiver” panel, and select “CRSF” as the protocol. Telemetry is optional here and will reduce your stick update rate due to those transmit slots being used for telemetry.

Remember to configure Serial Port (via Ports tab) and choes Serial Receiver

Package Included:

  • ELRS 2.4G Receiver * 1

  • T antenna * 1

  • Connecting wire * 4 (black, red, white, yellow)

  • Heat shrinkable sleeve * 1

Bind procedure:

1. Supply power to the ELRS receiver. After three times of power on and power off, the ELRS receiver enters the binding state. The LED will start to double flash, which means the ELRS receiver enters the binding mode

2. Make sure that the LED flashes quickly twice, indicating that the receiver is in binding mode;

3. Ensure that the RFTX module or radio transmitter enters the binding state and sends binding signals;

4. If the receiver has a stable light, it is bound.
