The world’s first AIO 5in1 F4 flight controller with integrated SPI 2.4GHz ExpressLRS receiver has been launched. The flight controller integrates SPI controlled 2.4GHz ExpressLRS receiver, Dshot protocol 4-in-1 ESC, 5.8GHz 40ch video transmitter and Betaflight OSD. Ultra-small size and ultra-stable remote control range can improve the range of the originals SPI receiver. And because the 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate and low latency, this flight controller is the one that all Race/Freestyle pilots needed. It is suitable for use in Tiny whoop Race or Toothpick Freestyle, and can also be used in 1S ultra-lightweight Nano Long Range platform.

Bind procedure:
1. Power the flight controller by connecting USB. Please make sure that the port driver of the flight controller is correctly installed on the computer, then open Betaflight Configurator(Latest version) to connect, enter to the “receiver” interface, and then click “Bind Receiver”, the red LED at the bottom of the flight controller will flash quickly, which means that the SPI ELRS receiver enters the bind mode. There is another way to make the receiver enter the bind mode: after connecting to the Betaflight configurator, move to the CLI interface and enter “bind_rx” in the command line.
2. After correctly connecting the ES24TX or ES24TX Lite/Slim module or DIY 2.4G ELRS TX module to your Opentx radio transmitter, copy the latest version of ELRS.LUA file to the SD card in the remote controller. The directory is “SD Card/Scripts/tools”, Then run ELRS.LUA and upgrade the specified TX frimware through Wifi, and then click “bind” to link with the SPI ExpressLRS receiver. Note: You need to adjust the Packet Rate to 500Hz from the ELRS interface of your radio controller before binding.
3. After the binding is successful, the Red LED at the bottom of the flight controller will getting to be solid, and the telemetry can be received at the same time.
4. The meaning of the LED status of the SPI receiver: the LED is getting to be solid, indicating that the bind is successful or the connection and communication is normal, the LED flashing quickly indicates that the receiver is in binding mode, and the LED flashing slowly indicates that the there is no signal received from the radio controller.
