4. Installation

4.1 Installation physique

The F4V3S Plus Flight Controller board has a standard 30.5x30.5mm mounting hole pattern, allowing it to be easily integrated into most FPV drone frames. Ensure proper spacing and vibration dampening using the provided standoffs and grommets.

• Mount the PDB at the bottom of your stack, securing it to the frame.
• Mount the F4V3S Plus Flight Controller board on top of the PDB using the provided standoffs.
• Mount the M8N GPS module on the top plate of your drone or in a location with a clear sky view, away from interference.

4.2 Schéma de câblage

Refer to the following diagram for connecting your F4V3S Plus Flight Controller to various peripherals such as ESCs, receiver, GPS, VTX, and camera. Pay close attention to voltage requirements and pin assignments.

Figure 4.1: Comprehensive wiring diagram for the F4V3S Plus Flight Controller, showing connections for receiver (SBUS/PPM), ESCs, GPS, VTX, camera, and power distribution. Note that the transmitter and receiver (RX/OSD) can only be used one at a time.

• Power (VBAT): Connectez votre batterie principale voltage to the VBAT pads on the PDB. The PDB will provide regulated 5V and 9V outputs.
• ESC : Connect the signal wires from your Electronic Speed Controllers (ESCs) to the M1-M6 pads on the flight controller. Connect ESC ground to FC ground.
• Récepteur:
  • For SBUS receivers, connect the SBUS signal wire to the SBUS pad.
  • For PPM receivers, short the PPM pad as indicated in the diagram and connect the PPM signal wire.
  • Connect receiver 5V and GND to the corresponding 5V and GND pads.
• GPS (M8N): Connect the GPS module to UART1 (TX1/RX1) for data and I2C (SDA/SCL) for the compass. Ensure 5V and GND connections are correct.
• Émetteur vidéo (VTX) : Connect VTX video input to the Video Out pad, and VTX power (5-26V) and ground to the PDB.
• Caméra: Connect camera video output to the Video In pad, and camera power (5V) and ground to the FC.
• Bande LED : Connect LED strips to the LED pad and 5V/GND.

4.3 Mise à jour du firmware

The F4V3S Plus Flight Controller comes pre-flashed with OMNIBUSF4SD(AIRB) firmware. If you need to update or re-flash the firmware:

• Download the latest Betaflight Configurator or INAV Configurator software.
• Connect the flight controller to your computer using a USB Type-C cable.
• In the configurator, select the correct target (OMNIBUSF4SD) and flash the desired firmware version.
• Follow the on-screen instructions for DFU mode if necessary.

4.4 Configuration du logiciel

After flashing, configure the flight controller using Betaflight or INAV Configurator:

• Connect to the flight controller via USB.
• Perform initial setup, including accelerometer calibration.
• Configure UARTs for your receiver, GPS, VTX telemetry, etc., according to your wiring.
• Set up your receiver protocol (e.g., SBUS, Crossfire, ELRS).
• Configure ESC protocol (e.g., DShot600).
• Set up modes (Arm, Angle, Acro, GPS Rescue, etc.).
• Verify motor direction and propeller installation.

5. Fonctionnement

Once the flight controller is fully installed and configured, you can proceed with operation. Always ensure a safe environment for flight.

• Vérification avant vol : Before each flight, verify all connections are secure, propellers are correctly installed, and battery is fully charged.
• Armement: Arm the drone using the configured switch on your remote controller. Ensure the drone is on a level surface for accurate accelerometer calibration at startup.
• Modes de vol : Utilize the configured flight modes (e.g., Angle, Acro, GPS Hold) as appropriate for your flying style and conditions.
• Fonctionnalité GPS : For GPS-dependent modes, wait for a sufficient number of satellites to be acquired before arming. The M8N GPS module provides reliable positioning.
• Désarmant: Disarm the drone immediately after landing or in an emergency situation.

6. Entretien

Regular maintenance helps ensure the longevity and reliable performance of your flight controller.

• Nettoyage: Inspectez régulièrement la carte pour détecter la présence de poussière, de saleté ou de débris. Utilisez une brosse douce ou de l'air comprimé pour nettoyer délicatement les composants. Évitez d'utiliser des liquides.
• Vérification de la connexion : Regularly inspect all solder joints and connectors for signs of wear, corrosion, or loose connections. Re-solder or replace as needed.
• Mises à jour du micrologiciel : Keep your flight controller firmware updated to benefit from new features, bug fixes, and performance improvements. Always back up your configuration before updating.
• Inspection physique: Check for any physical damage to the PCB, components, or mounting hardware after crashes or hard landings.
