• 1 x Raspberry Pi 4 Model B 8GB board

Note: Additional accessories such as a power supply, MicroSD card, case, and cables are sold separately.

4. Impostazione

Follow these steps to set up your Raspberry Pi 4 Model B:

1. Prepare MicroSD Card: Download the official Raspberry Pi OS (or your preferred operating system) from the Raspberry Pi website. Use a tool like Raspberry Pi Imager to write the OS image to a MicroSD card (minimum 8GB, Class 10 recommended).
2. Inserire la scheda MicroSD: Carefully insert the prepared MicroSD card into the MicroSD card slot on the Raspberry Pi board.
3. Connetti le periferiche:
   • Connect a keyboard and mouse to the USB 2.0 or USB 3.0 ports.
   • Connect your display(s) to the micro HDMI ports using appropriate micro HDMI to HDMI cables. The Raspberry Pi 4 supports dual 4K displays.
   • (Optional) Connect an Ethernet cable to the Gigabit Ethernet port for wired network access.
4. Collegare l'alimentazione: Connect a compatible USB-C power supply (5V/3A minimum) to the USB-C power input port. The Raspberry Pi will power on automatically.
5. Avvio iniziale: The Raspberry Pi will boot up, and you should see the operating system desktop on your connected display. Follow the on-screen instructions for initial setup, including setting your locale, password, and connecting to Wi-Fi if not using Ethernet.

6. Manutenzione

To ensure the longevity and optimal performance of your Raspberry Pi 4 Model B, consider the following maintenance tips:

• Raffreddamento: The Raspberry Pi 4 can generate heat under heavy load. Consider using a heatsink or a fan case to maintain optimal operating temperatures.
• Aggiornamenti software: Regularly update your operating system and installed software to benefit from the latest features, bug fixes, and security patches. Use the command sudo apt update && sudo apt full-upgrade nel terminale.
• Spegnimento sicuro: Always shut down your Raspberry Pi properly through the operating system menu (e.g., "Shutdown" or "Reboot") before disconnecting power. This prevents data corruption on the MicroSD card.
• Alimentazione elettrica: Use a stable and sufficient power supply (5V/3A USB-C) to avoid unexpected shutdowns or performance issues.
• Ambiente: Keep the Raspberry Pi in a clean, dry environment, away from dust and extreme temperatures.

7. Risoluzione Dei Problemi

Ecco le soluzioni ai problemi più comuni che potresti riscontrare:

• No Boot/Blank Screen:
  • Ensure the MicroSD card is properly inserted and has a valid OS image.
  • Verify the power supply is connected and provides sufficient power (5V/3A).
  • Check micro HDMI cable connections and ensure the display is on the correct input.
• Problemi di connettività di rete:
  • For Wi-Fi, ensure correct SSID and password are entered during setup.
  • For Ethernet, check cable connections and router status.
  • Riavviare il Raspberry Pi.
• Periferiche non funzionanti:
  • Prova a collegare la tastiera/il mouse a porte USB diverse.
  • Ensure peripherals are powered if they require external power.
  • Check for any specific driver requirements for your peripherals.
• Surriscaldamento:
  • Garantire una ventilazione adeguata.
  • Consider adding a heatsink or fan for improved cooling, especially under continuous heavy load.
