• Description

 

BETAFPV Nano receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

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 in Facebook 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.

 

 

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.

BetaFPV ExpressLRS receiver config1

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

BetaFPV ExpressLRS Receiver Config2

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.

BetaFPV ExpressLRS receiver config3

Nano receiver could enter binding status by power on/off three times.

  • 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.

Note: Binding once and the receiver will store the binding information. Re-power and the connect successfully auto.

BetaFPV elrs 915 nano reciever

These are great I have already bought over 5. There is a small learning curve, but once I figured out the wifi updating method I have had very good luck with these! Now I can get one bound and fully set up within 5 minutes or so!!

BetaFPV 2.4 Nano RX

Stay away from this receiver until the WiFi works correctly with enough power. Mein got bricked.
