Proper wiring is critical for the safe and correct operation of your flight controller. Refer to the diagram below for typical connections in a fixed-wing setup.
Figure 7: Fixed Wing (Plane) Wiring Diagram for F405-WMO
5.1 Key Connections
- Battery (BAT+) / ESC: Connect your main flight battery (2-6S LiPo) to the BAT+ pads. ESCs (Electronic Speed Controllers) for motors are connected to S1, S2, S3, etc., as per your motor configuration. Ensure correct polarity.
- Reseptè (RX): Connect your receiver (e.g., SBUS, CRSF) to the appropriate UART RX pad. UART2-RX has a built-in inverter for SBUS.
- GPS: Connect GPS module to a spare UART (e.g., UART4(SERIAL4)). Ensure SDA/SCL for compass if applicable.
- Camera (CAM): Connect your FPV camera to the CAM input.
- Transmetè Videyo (VTX): Connect your VTX to the VTX output. The FC provides filtered Vbat for VTX and camera.
- OSD: The AT7456E OSD is integrated.
- Buzzer: Connect a passive buzzer to the dedicated pads or use the USB/Beep Extender.
- USB: Use the provided USB Type-C extender for connecting to your computer for firmware flashing and configuration.
- dirije: The board has an LED indicator (Red for 3.3V, Green for FC Status).
5.2 Enstriksyon soude
The board is shipped unsoldered. Use appropriate soldering techniques to connect the Dupont 2.54 pins and other components. Ensure clean and strong solder joints to prevent intermittent connections or shorts.
6. Firmware Flashing and Configuration
The F405-WMO supports both ArduPilot and INAV firmware. Choose the firmware that best suits your application.
6.1 Flache Firmwèr la
- Download the latest firmware for your chosen flight software (ArduPilot: MatekF405-TE or INAV: MATEKF405TE_SD) from the official Matek Systems website or the respective firmware project pages.
- Connect the F405-WMO to your computer using the USB Type-C extender.
- Enter DFU mode by holding the DFU button while plugging in the USB, or by using the DFU utility in your flight software configurator.
- Use the appropriate configurator software (e.g., INAV Configurator, Mission Planner for ArduPilot) to flash the downloaded firmware.
6.2 Inisyal Konfigirasyon
After flashing, connect to the configurator software and perform the following initial steps:
- Kalibrasyon Capteur: Calibrate the accelerometer, gyroscope, and compass (if connected).
