Maintenance

• Cleaning: Use a soft, dry cloth to clean the display and board. Avoid abrasive materials or harsh chemicals.
• Storage: Store the board in a cool, dry environment, away from direct sunlight and extreme temperatures.
• Handling: Handle the board by its edges to avoid touching sensitive components. Static electricity can damage electronic components, so use anti-static precautions when handling.
• Software Updates: Regularly check for updates to the ESP-IDF framework, Arduino core for ESP32, and relevant libraries to ensure optimal performance and security.

Troubleshooting

• Board Not Powering On: Ensure the USB Type-C cable is securely connected to both the board and a powered USB port. If using a battery, verify it is charged and correctly connected.
• Computer Not Recognizing Board: Check if the necessary USB-to-serial drivers are installed. Try a different USB port or cable.
• Display Not Working: Verify that the display is correctly connected to the board. Ensure your code initializes the ST7789T3 display driver correctly and that the backlight pin is enabled.
• Touchscreen Unresponsive: Confirm that the CST816D touch chip is correctly initialized in your firmware and that the I2C communication is functioning.
• Firmware Upload Failure: Ensure the correct board and port are selected in your IDE. Try holding down the BOOT button while pressing and releasing the RST button before uploading.
• Wi-Fi/Bluetooth Connectivity Issues: Double-check your network credentials and ensure the antenna is not obstructed. Verify that your code correctly implements the Wi-Fi or Bluetooth protocols.
