Wiring Diagram
Method 1： Plug and play

Method 2, Direct soldering.

Power supply
The power distribution logic for the F405 WING APP is as follows:

The 9V pad uses a VTX&CAM BEC for power supply. When the VTX&CAM BEC switches to another voltage through the pad jumper, the 9V pad will output the corresponding voltage.
The Vx pin headers use a Servo BEC for power supply. When the Servo BEC switches to another voltage through the pad jumper, the Vx pin headers will output the corresponding voltage.
Note: If your ESC supports BEC output, do not connect the ESC BEC red wire to the Vx pin headers, as this may burn the ESC or Servo BEC.
The default voltage for the FC BEC is 5.2V, with power output divided into three directions:
• The first path directly outputs to the 5V pad.
• The second path outputs to the onboard chip and 4V5 pad through a diode.
• The third path outputs to the LED connector through a self-recovering fuse and reverse connection protection circuit.

Please note that the FC BEC can provide a continuous current of 2.4-2.5A and a peak current of 3A. The onboard chip requires less than 1A of power, GPS and receivers generally require less than 0.1A, and the wireless controller requires 0.1A.If the LED connector uses a maximum of 1.3A, the 5V pad will have no remaining capacity. If the LED connector is not used, the 5V pad will have a 1.3A surplus.

The limit for the LED connector power supply is approximately 68 pieces of Speedy Bee 5050 LED strip beads. Do not exceed this limit. To test if other brands of LED strips meet the power requirements, you can take the following steps:

After connecting the LED strip, let the flight controller be powered and idle for 10 minutes. Observe if the color of the LED strip suddenly dims and feel the wireless board with your hand. If it feels very hot, the power supply is insufficient, and you need to reduce the number of LED beads.
You can also use a multimeter to test the voltage of the 5V pad or the LED strip power pad. If the voltage is below 5V, it indicates that the power supply is insufficient, and you need to reduce the number of LED beads.

Part3 Firmware upgrade and APP connection

Firmware upgrade
Speedy Bee F405 WING APP not supporting wireless firmware flashing, please update the firmware on a computer. Follow these steps:

Press and hold the BOOT button , and connect the FC to the computer via USB cable.
Open the INAV Configurator on your computer, go to the “Firmware Flasher ” page, select the flight controller target as “SPEEDYBEEF405WING”, and then flash the firmware.
To flash Ardupilot firmware, follow the same steps as above, select “Load Firmware [local]”, and then flash the firmware.

APP Connection
Connecting INAV Firmware to Speedy bee APP.
Check the color of the wireless status indicator .
If it’s slow flashing green, open the Speedy Bee app and follow the steps to connect to the corresponding product.

APP connection
Check the color of the wireless status indicator. If it’s not flashing white, press the BOOT button for 6 seconds to switch to white.
Then connect to the “Speedybee F405Wing” Wi-Fi and open QGroundControl, it will automatically connect. Connecting Ardupilot firmware to QGroundControl app.

*All motor/servo outputs are DShot and PWM capable. However, mixing DShot and normal PWM operation for outputs is restricted into groups, ie. enabling DShot for an output in a group requires that ALL outputs in that group be configured and used as DShot, rather than PWM outputs. LED, which corresponds to PWM12, is set as the default output for NeoPixel1. Therefore, if you need to use PWM11 as an output, you need to disable the NeoPixel1 function on PWM12.
