3.2 Wiring Diagram Example

Below is an example of a typical wiring setup, demonstrating how various components like GPS, camera, VTX, and ESCs connect to the F405 WING MINI.

3.3 PWM Outputs and Servo Control

The F405 WING MINI provides up to 11 PWM outputs, 9 straight-pin headers, and 3 reserved solder pads for motor and servo control. This makes it suitable for a variety of fixed-wing aircraft layouts, including conventional, V-tail, flaperon-equipped, and VTOLs. Refer to the instructions for detailed output settings specific to your aircraft type.

4. Operating Instructions

4.1 Firmware Selection (INAV / ArduPilot)

The F405 WING MINI supports both INAV and ArduPilot firmwares. INAV offers a user-friendly setup for FPV flight handling, while ArduPilot provides advanced capabilities for more challenging flying styles. Choose the firmware that best suits your experience level and desired flight characteristics.

4.2 Wireless Configuration and Tuning (Wireless USB Extender)

The SpeedyBee F405 WING MINI Wireless USB Extender allows for convenient wireless configuration and tuning. Long press the BOOT button for 6 seconds to switch between modes:

• BLE mode: Connect to the SpeedyBee APP.
• Wi-Fi (AP) mode: Connect to SpeedyBee APP, QGroundControl APP, MissionPlanner, etc. Default Wi-Fi password: 88888888.
• Wi-Fi (STA) mode: Connect to QGroundControl APP, MissionPlanner, etc.
  1. Turn on Personal Hotspot;
  2. Set hotspot, locate NAME/Device Name/Hotspot name/etc.;
  3. Change the current name to eFLY and the password is, 88888888.
• Wireless off mode.

Important for INAV/ArduPilot:

• INAV: Ensure the MSP switch on UART 6 is turned on and set to a baud rate of 115200.
• ArduPilot: Ensure Serial 6 is set to a baud rate of 115200 and protocol Mavlink2.

4.3 Dual Analog Camera Switching

The F405 WING MINI supports dual analog camera switching. By default, it uses Camera1 Video Input (C1). You can switch between C1 and C2 using ArduPilot Relay or INAV Modes/USER settings. Both cameras must have the same video format (PAL or NTSC).

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your flight controller.

• Firmware Updates: Keep your flight controller firmware updated to the latest version to benefit from new features and performance enhancements. Use the SpeedyBee APP or relevant ground station software for updates.
• Physical Inspection: Periodically inspect all connections for secure fit and any signs of wear or damage.
• Cleaning: Keep the board clean from dust and debris. Use a soft brush or compressed air if necessary.
• Buzzer Mute Switch: Utilize the buzzer mute switch during configuration to avoid unnecessary noise.

6. Troubleshooting

While the SpeedyBee F405 WING MINI is designed for reliability, issues may occasionally arise. Here are some general troubleshooting tips:

• No Power/No Lights:
  • Check battery connections and voltage. Ensure it's within the 7-26V (2-6S LiPo) range.
  • Verify all power cables are securely connected to the PDB.
• Connection Issues (Wireless Extender):
  • Ensure the Wireless USB Extender is in the correct mode (BLE or Wi-Fi AP/STA).
  • Double-check Wi-Fi password (88888888) if using AP mode.
  • For STA mode, ensure your personal hotspot is correctly configured with the name eFLY and password 88888888.
  • Verify MSP/Serial settings and baud rates (115200) in INAV/ArduPilot for UART 6/Serial 6.
• Flight Instability:
  • Recalibrate IMU (Gyro & Accelerometer).
  • Check motor and servo connections and ensure correct PWM output settings for your aircraft type.
  • Review PID tuning parameters in your chosen firmware (INAV/ArduPilot).
• Camera Switching Not Working:
  • Ensure both cameras are analog and use the same video format (PAL or NTSC).
  • Verify camera switching settings in ArduPilot Relay or INAV Modes/USER.

For more specific issues, consult the official SpeedyBee documentation or community forums for INAV and ArduPilot.
