3.1. General Wiring Diagram

3.2. Full Socket Version Wiring

For the full socket version, specific connections are provided for various peripherals. Note the jumper setting for Digital Image Transmission.

3.3. Soldering Tips

The F722 Flight Stack features large solder pads positioned away from components, making soldering easier, especially for beginners. Ensure proper soldering techniques are used to prevent short circuits and ensure reliable connections.

3.4. Firmware Installation

The F722 Flight Controller supports Betaflight firmware. The recommended firmware name is DAKEFPVF722. The ESCs support BlueJay firmware and bidirectional DSHOT. Refer to the respective firmware documentation for detailed installation and configuration instructions.

4. Operating Instructions

Once the Flight Stack is correctly wired and firmware is flashed, you can proceed with configuration and operation.

4.1. OSD Configuration

The F722 Flight Controller includes a built-in OSD (On-Screen Display) module, allowing for one-step parameterization directly through your FPV video feed. Use the Betaflight OSD tab to configure displayed elements.

4.2. ESC Protocol

The ESCs support the DSHOT600 protocol, providing smooth and powerful acceleration. Ensure your flight controller is configured to use DSHOT600 for optimal performance.

4.3. 2.4G ELRS Nano Receiver

If using the 2.4G ELRS Nano receiver, it offers low latency and a high refresh rate (up to 500Hz), ideal for FPV racing. Ensure proper binding with your ELRS transmitter module. The frequency range is 2400 MHz to 2500 MHz.

5. Maintenance

To ensure the longevity and reliable performance of your 9IMOD F722 Flight Stack, follow these general maintenance guidelines:

• Keep Clean: Regularly inspect the boards for dust, dirt, or debris. Use compressed air or a soft brush to gently clean the components.
• Inspect Connections: Periodically check all soldered joints and connectors for signs of wear, corrosion, or loose connections. Re-solder or replace as necessary.
• Avoid Physical Damage: Protect the flight stack from impacts and excessive vibrations. Use the provided silicone vibration absorbers during installation.
• Proper Storage: When not in use, store the flight stack in a dry, anti-static environment.

6. Troubleshooting

This section provides solutions to common issues you might encounter.

6.1. Common Issues

• No Power/Intermittent Power: Check all power connections, including the XT60 connector and battery input. Ensure the battery is fully charged and within the supported voltage range (3-8S Lipo).
• Motors Not Spinning/Erratic Behavior: Verify ESC connections to the flight controller and motors. Check motor protocol settings in Betaflight. Re-calibrate ESCs if necessary.
• No OSD Display: Ensure your FPV camera and VTX are correctly connected and powered. Check OSD settings in Betaflight.
• Receiver Not Responding: Confirm the receiver is correctly wired and bound to your transmitter. Check UART settings in Betaflight for the receiver.
• Analog VTX Not Displaying: The analog VTX typically connects to UART 5 on the F722 Flight Controller. Verify this connection and the VTX settings.
• GPS Module Not Working: Ensure the GPS module is connected to a compatible UART and configured correctly in Betaflight. The GPS module must support the u-blox protocol.

6.2. User Tips

• For analog VTX connections, use UART 5 on the F722 Flight Controller.
• Take advantage of the large solder pads for easier and more reliable connections, especially if you are new to FPV building.
• Regularly update your Betaflight and BlueJay firmware to benefit from the latest features and bug fixes.
