10. Troubleshooting

If you encounter issues with your ESP32 S3 Development Board, consider the following troubleshooting steps:

• Board Not Powering On:
  • Check the USB cable connection and ensure it's securely plugged into both the board and your computer/power adapter.
  • Try a different USB cable or power source.
  • Verify that your power source provides sufficient current (typically 500mA to 1A).
• Failed to Upload Code:
  • Ensure the correct board and COM port are selected in your IDE (Arduino IDE, Thonny).
  • Press and hold the BOOT button, then press and release the RST button, then release the BOOT button to enter download mode before uploading.
  • Check if the necessary drivers (e.g., CH343P driver) are installed correctly on your computer.
  • Try a different USB port or computer.
• Serial Monitor Issues:
  • Verify that the baud rate in your serial monitor matches the baud rate set in your code.
  • Ensure the correct COM port is selected.
• Wi-Fi/Bluetooth Connectivity Problems:
  • Double-check your network credentials (SSID, password) in your code.
  • Ensure the board is within range of your Wi-Fi router or Bluetooth device.
  • Verify that the Wi-Fi/Bluetooth antenna is properly connected (if external).
