Specific API usage and examples for these connectivity features are available in the ESP-IDF programming guides.

4. Maintenance and Care

To ensure the longevity and optimal performance of your ESP32-H2-DevKitM-1-N4S Development Board, please follow these maintenance guidelines:

• Handle with Care: The board contains sensitive electronic components. Avoid dropping it or subjecting it to physical shocks.
• Keep Dry: Protect the board from moisture, humidity, and liquids. Water damage can cause irreversible harm.
• Temperature Control: Operate and store the board within its specified temperature range. Avoid extreme heat or cold.
• Cleanliness: Keep the board free from dust and debris. If cleaning is necessary, use a soft, dry brush or compressed air. Do not use liquid cleaners.
• Static Electricity: Take precautions against electrostatic discharge (ESD) when handling the board, as ESD can damage components.

5. Troubleshooting

If you encounter issues with your ESP32-H2-DevKitM-1-N4S Development Board, consider the following common troubleshooting steps:

• No Power/LEDs Off: Ensure the USB-C cable is securely connected to both the board and your computer/power source. Try a different USB port or cable.
• Failed Firmware Upload: Verify that the correct COM port is selected in your flashing tool. Ensure all necessary drivers are installed. Try pressing the BOOT button (SW1) while connecting or resetting the board, then releasing it during the upload process.
• Communication Errors: Check if the correct baud rate is set for serial communication. Ensure no other applications are using the COM port.
• Unexpected Behavior: Review your code for logical errors. Ensure all external components are correctly wired and powered.
