5. Operating Instructions

5.1 Basic Operation

Once powered, the board will execute the loaded firmware. The dual LCD displays will show the programmed interface. If your version includes touch functionality, you can interact with the displays directly. For non-touch versions, external input methods (e.g., buttons connected to GPIOs) will be necessary.

5.2 Programming and Development

The ESP32-S3 is a powerful microcontroller. You can develop applications using various frameworks. The Waveshare Wiki provides examples and guides for common use cases, including display control, Wi-Fi/Bluetooth communication, audio processing, and AI model integration.

5.3 AIoT Applications

Leverage the ESP32-S3's capabilities for AIoT projects. This includes voice recognition for smart assistants, image processing on the displays, and data collection/transmission via Wi-Fi or Bluetooth to cloud services or other devices.

6. Maintenance

6.1 Care and Handling

• Avoid exposing the board to extreme temperatures, humidity, or direct sunlight.
• Handle the board by its edges to prevent damage to components and static discharge.
• Do not apply excessive force to the displays or connectors.

6.2 Cleaning

To clean the board, use a soft, dry, anti-static cloth. For the LCD screens, a microfiber cloth lightly dampened with a screen cleaner (if necessary) can be used. Avoid harsh chemicals or abrasive materials.

6.3 Storage

When not in use, store the development board in an anti-static bag in a cool, dry environment to protect it from dust and static electricity.

7. Troubleshooting

7.1 No Power

• Ensure the USB-C cable is securely connected to a power source and the board.
• If using a battery, check that it is charged and correctly connected to the JST header.
• Try a different USB-C cable or power adapter.

7.2 Displays Not Working

• Verify that the FFC 18PIN cable is properly seated in both the display and main board connectors.
• Ensure your firmware includes the correct display initialization code.
• Check for any physical damage to the FFC cable or display connectors.

7.3 Connectivity Issues (Wi-Fi/Bluetooth)

• Confirm that your code correctly initializes and configures Wi-Fi or Bluetooth.
• Check for proper antenna connection (if external) or ensure the onboard antenna is not obstructed.
• Ensure the device you are trying to connect to is discoverable and within range.

7.4 Software/Firmware Issues

If you encounter unexpected behavior or errors related to your code, consult the Waveshare Wiki for common issues and solutions. The ESP32 community forums are also an excellent resource for programming-related problems.
