3. Opsætning og ledningsføring
Proper wiring is crucial for the safe and correct operation of the flight controller. Refer to the pinout diagram below for connection details.
Figure 2: FOXEER F722 V4 Pinout Diagram (Top View).
3.1. Montering
The flight controller has a size of 37x37mm with 30.5x30.5mm mounting holes (Φ4mm). Use the provided rubber columns to securely mount the FC to your drone frame, ensuring vibration isolation.
3.2. Strømtilslutning
Connect your LiPo battery (4S to 8S) to the designated power pads. Ensure correct polarity. The FC provides regulated 5V and 10V outputs for your FPV camera, VTX, and receiver.
3.3. Perifere forbindelser
- ESC'er: Connect ESC signal wires to the appropriate motor outputs (M1-M4/M8).
- Modtager: Connect your receiver to one of the UARTs (e.g., RX4 for SBUS/CRSF).
- FPV-kamera: Connect to the CAM input and 5V/10V output.
- Videosender (VTX): Connect to the VTX output and 5V/10V output. Smart Audio is supported for VTX control.
- GPS/Compass: Connect to an available UART (e.g., TX/RX pads).
- Summer: Connect to the dedicated buzzer pads.
- lysdioder: Connect 2812 LEDs to the LED pad.
- DJI/HDzero: Use the dedicated connector for digital FPV systems.

4. Betjeningsvejledning
4.1. Firmware-flashing
The FOXEER F722 V4 uses BetaFlight firmware. To flash or update the firmware:
- Download the latest BetaFlight Configurator from the official BetaFlight webwebsted.
- Connect the flight controller to your computer using a USB Type-C cable.
- Enter DFU mode by holding the BOOT button while plugging in the USB cable, or by using the DFU option in BetaFlight Configurator.
- Select the target firmware "FOXEERF722V4" in the BetaFlight Configurator and flash the firmware.
4.2. BetaFlight Configuration
After flashing, connect to the BetaFlight Configurator to set up your flight controller:
- Fanen Porte: Configure UARTs for your receiver, VTX (Smart Audio), GPS, and ESC telemetry.
- Fanen Konfiguration: Set up ESC protocol (e.g., DShot), accelerometer calibration, and other basic settings.
- Fanen Motorer: Test motor direction and order.
- OSD-fane: Customize the on-screen display elements for your FPV feed.
- Blackbox Tab: Configure black box logging rates and parameters.
- CLI Tab: For advanced configurations or specific settings not available in the GUI. X8 support requires CLI commands.
5. Vedligeholdelse
Regular maintenance helps ensure the longevity and reliable performance of your flight controller.
- Visuel inspektion: Periodically inspect the board for any signs of damage, loose connections, or corrosion.
- Rensning: Gently clean the board with isopropyl alcohol and a soft brush if dust or debris accumulates. Ensure the board is powered off and disconnected before cleaning.
- Firmwareopdateringer: Keep the firmware updated to benefit from performance improvements and bug fixes.
- Opbevaring: Når den ikke er i brug, skal den opbevares tørt og antistatisk, væk fra ekstreme temperaturer.
6. Fejlfinding
If you encounter issues with your FOXEER F722 V4 Flight Controller, consider the following troubleshooting steps:
- Ingen strøm/LED'er slukket:
- Kontroller batteriforbindelsen og polariteten.
- Bekræft strømforsyningen voltage is within the 4S-8S LiPo range.
- Undersøg for kortslutninger på kortet eller tilsluttede eksterne enheder.
- Cannot Connect to BetaFlight Configurator:
- Ensure correct USB Type-C cable is used (data capable, not just charging).
- Install necessary VCP (Virtual COM Port) drivers.
- Prøv en anden USB-port eller computer.
- Attempt to connect in DFU mode for firmware re-flash.
- Gyro/Accelerometer Issues:
- Perform accelerometer calibration in BetaFlight Configurator on a level surface.
- Check for excessive vibrations on the drone frame; ensure FC is soft-mounted.
- Peripheral Not Working (e.g., Receiver, VTX):
- Verify wiring connections to the correct UARTs and power outputs.
- Check UART configuration in BetaFlight Configurator (e.g., Serial RX for receiver, Peripherals for Smart Audio).
- Ensure peripherals are powered correctly by the FC's BEC outputs.
