3. Setup

3.1 Required Components (Not Included)

• Power Supply: 2.5A Micro USB Power Supply (recommended for stable operation).
• Storage: Class 10 Micro SD Card (minimum 8GB, pre-loaded with Pi 3 B+ compatible software).
• Input Devices (Optional): USB or Bluetooth keyboard/mouse.
• Display (Optional): HDMI or DSI compatible display.

3.2 Initial Setup Steps

1. Prepare Micro SD Card: Download a compatible operating system image (e.g., Raspberry Pi OS) from the official Raspberry Pi website. Use an imaging tool (like Raspberry Pi Imager) to write the OS image to your Class 10 Micro SD card.
2. Insert Micro SD Card: Gently insert the prepared Micro SD card into the card slot on the underside of the Raspberry Pi board.
3. Connect Peripherals:
   • Connect your HDMI display to the HDMI port on the Raspberry Pi.
   • Connect your USB keyboard and mouse to the available USB ports.
   • (Optional) Connect an Ethernet cable to the Ethernet port for wired network access.
4. Apply Power: Connect the 2.5A Micro USB power supply to the Micro USB power port on the Raspberry Pi. The device will automatically power on and begin booting.
5. First Boot: Follow the on-screen instructions to complete the initial setup of the operating system, including setting up Wi-Fi, language, and user accounts.

4. Operating

4.1 Basic Operation

Once the operating system is installed and configured, your Raspberry Pi is ready for use. You can interact with it via the connected keyboard, mouse, and display, similar to a traditional desktop computer. The Raspberry Pi OS provides a graphical user interface (GUI) for ease of use.

4.2 Software Installation and Updates

Software can be installed via the graphical "Add/Remove Software" utility or through the command line using `apt` commands (e.g., `sudo apt update`, `sudo apt install [package_name]`). Regular updates are recommended to ensure system stability and security.

4.3 GPIO Usage

The 40-pin GPIO header allows for advanced projects involving physical computing. You can connect various sensors, actuators, and other electronic components to control them programmatically using languages like Python.

Refer to the official Raspberry Pi documentation for detailed guides on GPIO programming and hardware interfacing.

5. Maintenance

• Software Updates: Regularly update your operating system and installed software packages to receive the latest features, bug fixes, and security patches. This can typically be done via the terminal using `sudo apt update` followed by `sudo apt upgrade`.
• Power Management: Always use a stable and sufficient power supply (5.1V / 2.5A) to prevent unexpected shutdowns or data corruption. Avoid disconnecting power without properly shutting down the operating system first.
• SD Card Care: Micro SD cards can wear out over time. Regularly back up your data and consider using high-quality, durable cards. Avoid frequent power cuts to minimize the risk of SD card corruption.
• Physical Environment: Keep the Raspberry Pi in a cool, dry, and well-ventilated area. Avoid exposing it to extreme temperatures, humidity, or dust. Consider using a protective case.

6. Troubleshooting

• No Power/Boot:
  • Ensure the power supply is correctly connected and meets the 5.1V / 2.5A specification.
  • Check the Micro SD card for proper insertion and ensure it has a valid operating system image.
  • Look for the red power LED (PWR) to be steadily lit and the green activity LED (ACT) to flash during boot.
• Display Issues:
  • Verify the HDMI cable is securely connected to both the Raspberry Pi and the display.
  • Ensure your display is set to the correct input source.
• Network Connectivity Problems:
  • For wired Ethernet, check the cable connection and router status.
  • For Wi-Fi, ensure the correct network name (SSID) and password are entered in the OS settings.
  • Restart your router and the Raspberry Pi.
• Peripheral Not Responding:
  • Try connecting USB devices to different USB ports.
  • For Bluetooth devices, ensure they are in pairing mode and correctly configured in the OS.
