The latest EFM8BB21F16G high speed control chip.

A 6-layer, 3-ounce copper-thick and high-quality PCB is adopted, and the layered layout of large current and small control signal is adopted to enhance the anti-jamming ability. 

The gold plating process on PCB surface can effectively improve the current resistance and heat dissipation ability of electric regulation.

Integrated RGB multi-color bright LED night light, night flight is even more dazzling.

We suggest our customers upgrade their modules and receivers' ELRS version to 3.3.0. Significantly,
the module and receiver have to be in the same ELRS version, otherwise, the frequency cannot match successfully.

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


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.

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.
