3.2 Cablejat

Connect your ESCs, receiver, VTX, camera, and GPS module to the appropriate pads on the flight controller. Refer to the pinout diagram (often available on the manufacturer's product page or community wikis) for specific connection points. Ensure all connections are soldered cleanly and securely to prevent intermittent issues or shorts.

• ESC: Connect ESC signal wires to the designated motor output pads.
• Receptor: Connect your SBUS, PPM, or Spektrum DSMX receiver to its respective port.
• VTX & Camera: Connect video input/output and power to the dedicated video pads.
• GPS: Connect the BN880 GPS module to the UART port configured for GPS.
• Potència: Provide main battery power to the designated VBAT pads, ensuring correct polarity.

3.3 Configuració del programari

Connect the flight controller to your computer via a USB cable. Use the Betaflight Configurator or INAV Configurator software to:

• Flash the latest firmware for your F4V3S board.
• Calibrate the accelerometer and gyroscope.
• Configure receiver protocols and channels.
• Set up flight modes, OSD elements, and PID tuning.
• Enable and configure peripherals such as GPS, barometer, and SmartAudio.

4. Funcionament

After successful setup and configuration, ensure all components are functioning correctly before flight. Always perform a pre-flight check.

• Armat: Arm the drone using the configured switch on your remote controller. Ensure propellers are clear before arming.
• Modes de vol: Utilize various flight modes (e.g., Angle, Acro, GPS Hold) configured in your flight control software.
• OSD Usage: Monitor real-time flight data such as battery voltage, current, flight time, and GPS coordinates directly on your FPV feed via the integrated OSD.
• VTX Control: Adjust VTX settings (power, channel) using SmartAudio via your OSD or remote control.

5. Manteniment

Regular maintenance ensures the longevity and reliability of your flight controller.

• Inspecció: Periodically inspect the board for any physical damage, loose connections, or corrosion.
• Neteja: Keep the board free from dust, dirt, and moisture. Use compressed air or a soft brush for cleaning.
• Actualitzacions de firmware: Regularly check for and install the latest firmware versions for Betaflight or INAV to benefit from bug fixes and new features.
• Configuració de còpia de seguretat: Always back up your flight controller configuration settings before performing firmware updates or significant changes.

6. Solució De Problemes

Si teniu problemes, tingueu en compte els passos habituals següents per resoldre'ls:

• Sense energia: Check battery connections, power distribution board (PDB), and flight controller power input pads for correct voltage i polaritat.
• No Connection to Configurator: Ensure USB drivers are installed. Try a different USB cable or port. Verify the correct COM port is selected.
• Motors que no giren: Check ESC connections, motor direction, and ESC calibration. Verify motor output in the configurator.
• Vol inestable: Recalibrate accelerometer. Check PID settings. Inspect propellers for damage. Ensure frame is rigid.
• L'OSD no es mostra: Verify OSD is enabled in the configurator. Check video input/output connections.
• El GPS no es bloqueja: Ensure GPS module is connected correctly and has a clear view of the sky. Check GPS settings in the configurator.
