3. Configurazione e cablaggio

Careful wiring is crucial for the proper function and safety of your FPV drone. Refer to the diagrams below for correct connections.

3.1 Flight Controller Wiring Diagram

This diagram illustrates the various connection points on the F722 Flight Controller:

• Telecamera: Connect your FPV camera to VBAT, GND, and VI (Video Input).
• 4-in-1 ESC: Connect the ESC signal wires (M1-M8) and power (VBAT, GND) to the corresponding pins.
• GUIDATO: Connect RGB LED strips to RGB, +5V, and GND.
• Posizione GPS: Connect GPS module to R3, T3, GND, +5V, SCL, SDA.
• DJI HD: Dedicated ports for DJI HD system (R1, R2, T1, T2, 9V, GND, VO).
• Ricevitore: Connect your receiver (ELRS, TBS, SBUS, IBUS, DSM2, DSMX) to the appropriate UART (RX/TX) pins, +5V, and GND.
• Cicalino: Connect a 5V buzzer to the BZ+ and BZ- pads.
• USB: Type-C port for connecting to a computer for configuration.

3.2 4-in-1 ESC Wiring Diagram

This diagram shows the connections for the 4-in-1 ESC:

• Motori: Connect your drone motors to M1, M2, M3, M4 pads. Ensure correct motor rotation direction during initial setup in Betaflight.
• Batteria: Solder the main battery lead (3-8S LiPo) to the BAT (+) and GND (-) pads. A capacitor (50V 1000uF recommended) should be soldered across the main battery pads to filter voltage picchi.
• Sensore di corrente: The ESC has an integrated current sensor. The current output (CUR) signal connects to the FC.

3.3 Stack Assembly

The Flight Controller and 4-in-1 ESC are designed to be stacked. Use the provided standoffs and screws to securely mount the FC on top of the ESC. Ensure the orientation is correct as per your drone frame and Betaflight configuration.

4. Istruzioni per l'uso

4.1 Firmware Flashing (Betaflight)

1. Download the latest Betaflight Configurator software to your computer.
2. Connect the F722 Flight Controller to your computer using a USB Type-C cable.
3. In Betaflight Configurator, navigate to the 'Firmware Flasher' tab.
4. Select the target firmware: JHEF7DUAL.HEX (or the latest recommended for F722).
5. Choose 'Full chip erase' and 'Flash Firmware'.
6. After flashing, the FC will reboot. Disconnect and reconnect if necessary.

4.2 Initial Configuration (Betaflight)

1. Connect the FC to Betaflight Configurator.
2. Go through the initial setup wizard or manually configure the following:
   • Scheda Porte: Configura gli UART per il tuo ricevitore, VTX, GPS, ecc.
   • Scheda Configurazione: Set up ESC protocol (DSHOT600 recommended), accelerometer calibration, board and sensor alignment, and other basic drone settings.
   • Scheda Motori: Test motor direction. If incorrect, reverse in BLHeliSuite32 or by swapping motor wires.
   • Receiver Tab: Verify receiver input and channel mapping.
   • Scheda Modalità: Set up arming switch, flight modes (Angle, Acro, Horizon), and other auxiliary functions.
   • Scheda OSD: Customize your On-Screen Display elements.
3. Save and Reboot after each significant change.

4.3 ESC Configuration (BLHeliSuite / BLHeli_S Configurator)

1. For BLHeli_S ESCs, use the BLHeli_S Configurator (available as a Chrome app or standalone).
2. Connect the FC to your computer and ensure it's connected in Betaflight.
3. In Betaflight, go to the 'Motors' tab and enable 'ESC/Motor/Servo Protocol' to DSHOT.
4. Disconnect from Betaflight and open BLHeli_S Configurator.
5. Connect to the ESCs via the FC (pass-through).
6. Read the current ESC settings and flash the latest BLHeli_S firmware if desired.
7. Configure motor direction, Damped Light, and other ESC-specific settings.
8. Save settings and disconnect.

4.4 Controlli pre-volo

• Assicurarsi che tutti i collegamenti siano sicuri e isolati.
• Verify motor rotation direction.
• Check prop direction and secure mounting.
• Confirm receiver functionality and failsafe settings.
• Perform a final check in Betaflight Configurator for any warnings or errors.

5. Manutenzione

• Ispezione regolare: Periodically check all solder joints and wire connections for looseness or damage.
• Pulizia: Keep the FC and ESC free from dust, dirt, and debris. Use compressed air or a soft brush. Avoid using liquids directly on the electronics.
• Protezione dall'umidità: Protect the electronics from moisture and water exposure. Consider conformal coating for added protection in wet environments.
• Gestione del calore: Ensure adequate airflow around the stack, especially for high-current ESCs, to prevent overheating.
• Aggiornamenti del firmware: Keep your Betaflight and BLHeli_S firmware updated to benefit from performance improvements and bug fixes. Always back up your configuration before updating.

6. Risoluzione Dei Problemi

6.1 No Power to FC/ESC

• Controllare la connessione della batteria: Ensure the LiPo battery is fully charged and correctly connected to the ESC.
• Inspect Main Power Leads: Verify that the main battery wires are securely soldered to the ESC pads and there are no shorts.
• Connessione USB: If only connecting via USB, ensure the cable is functional and the FC drivers are installed on your computer.

6.2 Motors Not Spinning / Incorrect Rotation

• Protocollo ESC: Confirm the correct ESC protocol (e.g., DSHOT600) is selected in Betaflight and BLHeli_S Configurator.
• Cablaggio del motore: Check that each motor is correctly wired to its corresponding ESC pad (M1-M4).
• Direzione del motore: If motors spin in the wrong direction, reverse them in BLHeli_S Configurator or by swapping any two motor phase wires.
• Arming Issues: Ensure the drone is armed correctly. Check Betaflight 'Modes' tab and 'Motors' tab for any arming prevention flags.

6.3 Connection Issues (Receiver, VTX, GPS)

• Configurazione UART: Verify that the correct UART port is enabled and configured for your peripheral in Betaflight 'Ports' tab.
• Cablaggio: Double-check the RX/TX, +5V, and GND connections for each peripheral.
• Mancata corrispondenza del protocollo: Ensure the communication protocol (e.g., CRSF for ELRS/TBS, SBUS) is correctly set in Betaflight and on the peripheral itself.

6.4 Unstable Flight / Jittery Motors

• Regolazione PID: Adjust PID values in Betaflight. Start with default settings for your frame and fine-tune as needed.
• Montaggio morbido: Ensure the FC and ESC are soft-mounted to reduce vibrations transmitted from the frame and motors.
• Bilanciamento dell'elica: Check for damaged or unbalanced propellers.
• Motor/ESC Desync: This can be caused by incorrect ESC timing or DSHOT settings. Adjust ESC settings in BLHeli_S Configurator.

7. Suggerimenti per l'utente

• Esegui il backup della configurazione: Always save a CLI dump of your Betaflight configuration before making major changes or firmware updates. This allows you to restore your settings easily.
• Inizia con i valori predefiniti: When encountering issues, try flashing the latest stable firmware and starting with default Betaflight settings for your board.
• Utilizzare un fermafumo: Before powering your drone for the first time after building or making significant changes, use a smoke stopper to prevent damage in case of a short circuit.
• Saldatura corretta: Ensure all solder joints are clean, shiny, and strong. Cold or bridged solder joints are a common cause of issues.
• Gestione dei cavi: Keep wiring neat and tidy to prevent interference, shorts, and damage from propellers.
