5. Setup and Installation

This section provides general guidelines for installing your GHF722AIO-HD Flight Controller and ESC. For detailed wiring diagrams and specific drone configurations, please refer to the Betaflight documentation and your drone's manual.

5.1 Pre-Installation Checks

• Ensure your drone frame is compatible with 25.5-26.5mm x 3mm mounting holes.
• Gather all necessary tools: soldering iron, solder, flux, wire strippers, heat shrink, multimeter.
• Familiarize yourself with the pinout diagrams of the flight controller and your drone's components (receiver, VTX, camera, GPS, etc.).

5.2 Mounting the Unit

1. Carefully place the shock reduction grommets into the mounting holes of the flight controller.
2. Mount the GHF722AIO-HD unit onto your drone frame using appropriate screws, ensuring it is securely fastened but not overtightened.
3. Ensure the arrow on the flight controller points towards the front of the drone.

5.3 Wiring Connections

Connect the following components to the flight controller. Always double-check polarity before soldering.

• Motors: Solder motor wires to the corresponding pads (M1-M4) on the ESC section.
• Power Input: Solder the XT60 connector (with 14AWG wires) to the main battery pads (+ and -).
• Receiver: Connect your receiver (e.g., SBUS, CRSF, Spektrum) to an available UART port (e.g., UART2 RX).
• Video Transmitter (VTX): Connect VTX power to a 5V or VBAT pad (depending on VTX voltage requirement) and VTX signal to the appropriate video output pad.
• Camera: Connect camera power to a 5V pad and camera signal to the video input pad.
• GPS (Optional): Connect GPS module to an available UART port (e.g., UART3 TX/RX).
• Buzzer (Optional): Connect a buzzer to the dedicated buzzer pads.

Caution: Incorrect wiring can damage the flight controller and other components. If unsure, seek professional assistance.

6. Operating Instructions

6.1 Firmware Flashing and Configuration

1. Connect to PC: Use the provided Type-C extension line and rotation board to connect the flight controller to your computer.
2. Install Drivers: Ensure necessary DFU drivers are installed for your operating system.
3. Betaflight Configurator: Open the Betaflight Configurator software (available at betaflight.com).
4. Flash Firmware: Select the target "JHEF7DUAL" and flash the recommended firmware (betaflight_4.4.2_jhef7Dual.hex).
5. Initial Setup: Follow the setup wizard in Betaflight Configurator to configure your receiver, motors, OSD, and other peripherals.
6. ESC Firmware: The ESC comes pre-flashed with BlueJay G-H-30.HEX (48K). If updating is required, use the BlueJay Configurator.

6.2 Pre-Flight Checks

• Verify motor direction and order in Betaflight.
• Check receiver stick inputs for correct response.
• Ensure all propellers are securely attached and in the correct orientation.
• Perform a range check of your radio system.
• Confirm battery voltage and health.

6.3 Flight

Once all checks are complete and you are in a safe flying environment, arm your drone and begin flight. Monitor OSD data for critical information such as battery voltage, current draw, and altitude.

7. Maintenance

• Regular Inspection: Periodically inspect the flight controller and ESC for any signs of physical damage, loose connections, or corrosion.
• Cleaning: Gently clean the board with isopropyl alcohol and a soft brush if dust or debris accumulates. Ensure the board is completely dry before powering on.
