Power Supply

The layout for the F405 WING MINI is as follows

1. FC BEC default output is 5.2V, supplied in two routes:

• The first route is directly supplied to the 5V solder pads.
• The second route is supplied through a diode to the onboard chip and the 4V5 solder pads.

Please note that FC BEC can provide 2A continuous current and 3A peak current.
The onboard chip requires power ≤ 1A, GPS and receiver ≤ 0.1A, and wireless controller ≤ 0.1A. If connecting high-power telemetry or VTX to the 5V solder pads, ensure the operating current is ≤ 0.8A.

2. The VTX power supply interface (Vv) can be set to two power ways: direct battery power or internal BEC 5V (shared with 5V4A Servo BEC).

• Factory setting is battery power, where Vv interface voltage is the same as the battery voltage.

Please note: Ensure the voltage of VTX and camera power supply matches the battery voltage, if not, damage may occur.

• By using VTX Power Supply Jumper, you can switch to 5V power supply. In this case, the Vv interface voltage will be 5V (if you choose this method, ensure the servo and VTX current are sufficient).

Please note: When Servo BEC Voltage Jumper is switched to 6V, the Vv interface voltage also switches to 6V.

3. Servo power supply (Vx pin header) defaults to being powered by Servo BEC at 5V. When Servo BEC is switched to 6V via Servo BEC Voltage Jumper, the voltage at the Vx pin header also switches to 6V.

Please note that if the ESC supports BEC output, do not connect the BEC red wire to the Vx pin header. Otherwise, it may damage the ESC or Servo BEC.
Alternatively, you can directly power it using the ESC’s BEC, but you need to disconnect Servo BEC Power Supply Jumper. In this way, the power supply for the Vx pin header comes from an ESC’s BEC.

4.Power supply recommendations:

• When using a digital VTX with a wide voltage input, you can use the default battery voltage for Vv.
• When using an analog VTX powered by 5V, you can switch Vv power supply voltage to Servo BEC’s 5V supply. In this case, you can install up to four 9g servos to avoid insufficient current.
• When using aircraft with 64 or 70 EDF Jets, Servo BEC power supply may not be sufficient for servos and landing gear. You can disconnect Servo BEC Power Supply Jumper and directly use the ESC’s BEC to power the devices.

Part 3 – Firmware Upgrade and APP Connection

Firmware Upgrade

SpeedyBee F405 WING MINI does not support wireless firmware flashing. Please update the firmware using a computer by following these steps:

①Press and hold the BOOT button while connecting the FC to your computer via a USB cable.

② Open the INAV Configurator on your computer and navigate to the “Firmware Flasher” page. Select the flight controller target as “SPEEDYBEEF405WING” and proceed with flashing the firmware.
③ To flash ArduPilot firmware, follow the same steps as above. Select “Load Firmware [local]” and proceed with flashing the firmware.

APP Connection

Connecting ArduPilot firmware to QGroundControl app
Check the color of the Wireless Status Indicator. If it’s not White Slow Flash, press the BOOT button for 6 seconds to switch to White.
Then connect to the “SpeedyBee eFLY-WIFI”, and open QGroundControl, it will be automatically connected.

*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.
