5.3. Basic Interaction

• The capacitive touch screen allows for direct interaction with the display.
• If a demo UI is loaded, you can navigate through functions by tapping or swiping on the screen.
• The board may include physical buttons (labeled 'Key' in the pinout) for additional control, depending on the loaded firmware.

6. Maintenance & Storage

6.1. Cleaning

• Always turn off the device before cleaning.
• Use a soft, lint-free cloth to gently wipe the display and board.
• Do not use harsh chemicals, abrasive materials, or excessive moisture, as these can damage the components.

6.2. Storage

• Store the development board in a dry place at room temperature (15°C - 35°C).
• Keep it away from direct sunlight, high temperatures, water, moisture, and corrosive environments.
• If not used for a long time, charge the device to approximately 50% every 3 months to protect battery life (if an external battery is connected).

7. Troubleshooting

• Board does not power on: Ensure the USB Type-C cable is securely connected and the power adapter is functioning. Check the ON/OFF button operation.
• Display is blank or flickering: Verify power supply. If using custom firmware, ensure the display initialization code is correct.
• Touch screen unresponsive: Check for any physical obstructions. If using custom firmware, ensure the touch controller is correctly initialized and drivers are loaded.
• Connectivity issues (WiFi/Bluetooth): Ensure antennas are properly connected (if external) and software configurations for WiFi/Bluetooth are correct.
• Firmware upload failure: Check USB connection, ensure correct drivers are installed on your computer (e.g., CH340C driver), and verify your development environment settings (e.g., COM port, board selection).
