3.2 Wiring

1. Power Connection: Connect the main battery lead (XT60/XT30) to the designated BAT+ and BAT- pads on the AIO board. Ensure correct polarity.
2. Motor Connections: Solder motor wires to the M1, M2, M3, M4 pads. Verify motor order and direction according to your flight controller software configuration.
3. Receiver Connection: Connect your receiver (e.g., SBUS, CRSF, ELRS) to the appropriate UART pads (e.g., RX1, TX1).
4. Video Transmitter (VTX) & Camera: Connect your VTX and FPV camera to the designated video in/out and power pads.
5. GPS/Other Peripherals: If using, connect GPS modules or other peripherals to available UARTs or I2C pads as required.

3.3 Firmware Flashing and Configuration

1. Install Drivers: Ensure necessary USB drivers (e.g., STM32 Virtual COM Port Driver, Zadig) are installed on your computer.
2. Connect to PC: Connect the AIO board to your computer using a USB-C cable.
3. Open Configurator: Launch the Betaflight Configurator (or INAV Configurator, depending on your firmware choice).
4. Flash Firmware: Navigate to the 'Firmware Flasher' tab. Select the correct target (e.g., GEP_F722_AIO) and the latest stable firmware version. Click 'Load Firmware [Online]' and then 'Flash Firmware'.
5. Initial Configuration: After flashing, connect to the flight controller. Go through the setup wizard or manually configure settings such as accelerometer calibration, receiver protocol, motor output protocol (e.g., DShot600), OSD, and modes.

4. Operating Instructions

Once the flight controller is installed and configured, follow these general operating guidelines:

1. Pre-Flight Check: Before each flight, visually inspect all connections, propeller tightness, and battery charge.
2. Arming Procedure: Ensure your drone is on a stable, level surface. Arm the motors using the designated switch on your radio transmitter. The flight controller's status LED will typically change to indicate armed status.
3. Disarming Procedure: Disarm the motors immediately after landing or in an emergency by using the designated switch.
4. Flight Modes: Utilize various flight modes (e.g., Angle, Acro, Horizon) configured in your flight controller software to suit your flying style and skill level.
5. Battery Management: Monitor battery voltage during flight. Land safely before the battery voltage drops below critical levels to prevent damage to the battery and drone.

5. Maintenance

Regular maintenance helps ensure the longevity and reliability of your GEP-F722-45A AIO.

• Cleaning: Periodically clean the board to remove dust, dirt, or debris. Use a soft brush or compressed air. Avoid using liquids directly on the electronics.
• Firmware Updates: Check for and install new firmware versions for your flight controller and ESCs regularly. Updates often include performance improvements, bug fixes, and new features.
• Connection Inspection: Routinely inspect all solder joints and wire connections for signs of wear, corrosion, or looseness. Re-solder or replace as necessary.
• Physical Damage Check: After any hard landing or crash, inspect the board for cracks, bent pins, or damaged components.

6. Troubleshooting

This section addresses common issues you might encounter:

6.1 No Power to Board

• Check Battery Connection: Ensure the main battery is properly connected and charged.
• Inspect Solder Joints: Verify that the main power leads (BAT+ and BAT-) are securely soldered to the board.
• Check for Shorts: Look for any accidental solder bridges or conductive debris that could cause a short circuit.

6.2 Motors Not Spinning

• Arming State: Ensure the flight controller is armed.
• Motor Protocol: Verify that the correct motor output protocol (e.g., DShot600) is selected in the Betaflight/INAV configurator.
• ESC Calibration: If using analog ESC protocols, ensure ESCs are calibrated. For DShot, calibration is not required.
• Motor/ESC Health: Test individual motors and ESCs using the motor tab in the configurator.

6.3 No Connection to Configurator

• USB Cable: Try a different USB-C cable. Some cables are for charging only and do not support data transfer.
• Drivers: Reinstall or update the necessary USB drivers (STM32 Virtual COM Port Driver).
• DFU Mode: If the board is not recognized, try putting it into DFU (Device Firmware Upgrade) mode by holding the BOOT button (if present) while plugging in USB, then attempt to flash firmware.
