2. Modalità di caricamento: To upload new firmware, press and hold the Stivale , quindi premere e rilasciare il pulsante Reset pulsante. Rilasciare il Stivale button after a moment. This puts the board into download mode.
3. Caricamento del codice: Compile and upload your code from your chosen IDE.

3.2 Utilizzo generale

• Alimentazione elettrica: The board can be powered via the USB-C port (5V) or through the 5V pin on the headers.
• Utilizzo GPIO: Connect external components and sensors to the GPIO pins as per your project requirements, ensuring proper voltage levels (3.3V logic).
• Debug: Utilize the USB-to-UART bridge for serial communication and debugging output.

4. Manutenzione

To ensure the longevity and optimal performance of your ESP32-S3-DevKitC-1/1U, follow these maintenance guidelines:

• Maneggiare con cura: Evitare di far cadere la tavola o di sottoporla a urti fisici.
• Scarica statica: Always handle the board in a static-safe environment to prevent damage to sensitive electronic components.
• Pulizia: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
• Magazzinaggio: Store the board in a cool, dry place, preferably in an anti-static bag, when not in use.
• Spegni: Disconnect power before making any changes to wiring or connecting/disconnecting peripherals.

5. Risoluzione Dei Problemi

If you encounter issues with your ESP32-S3-DevKitC-1/1U, consider the following troubleshooting steps:

• Nessun LED di alimentazione: Ensure the USB-C cable is securely connected to both the board and a working USB port on your computer or power adapter. Try a different cable or port.
• Errori di caricamento:
  • Verify that the correct board and COM port are selected in your IDE.
  • Ensure the board is in download mode (press and hold BOOT, then press and release RESET, then release BOOT).
  • Check for driver issues for the USB-to-UART bridge.
• Serial Monitor Issues: Confirm that the baud rate in your serial monitor matches the baud rate set in your code.
• Periferica non funzionante: Double-check your wiring connections and ensure that the correct GPIO pins are being used and configured in your code. Verify external component power supply.
• Comportamento inaspettato: A simple reset (pressing the RESET button) can often resolve temporary software glitches.
