- Keep out of reach of small children due to small components.
4. Pokyny k nastavení
Follow these steps to assemble and prepare your Raspberry Pi 4 Starter Kit:
4.1. Installing the Raspberry Pi into the Cooling Case
- Carefully place the Raspberry Pi 4 board into the bottom part of the cooling case, aligning the ports with the case openings.
- Attach the fan to the designated pins on the Raspberry Pi's GPIO header (typically 5V and Ground pins). Refer to the case's specific instructions for fan connection.
- Secure the top part of the cooling case, ensuring all components are properly seated and the fan is unobstructed.

4.3. Připojení periferií
Connect your monitor(s) using the HDMI ports, a keyboard and mouse to the USB ports, and the Ethernet cable if a wired network connection is desired. The Raspberry Pi 4 supports dual 4K displays via its two micro-HDMI ports.
4.4. Zapnutí
Once all peripherals are connected, plug the USB Type-C power supply into the Raspberry Pi's power port and then into a wall outlet. The Raspberry Pi will automatically begin to boot up.
5. Návod k obsluze
The Raspberry Pi 4 runs a Linux-based operating system, typically Raspberry Pi OS. Upon first boot, you may be guided through an initial setup wizard to configure language, keyboard layout, Wi-Fi, and update software.
5.1. Cooling Performance
The included cooling case significantly improves thermal management. Without active cooling, the Raspberry Pi 4 can reach high temperatures under heavy load, potentially leading to performance throttling.

5.2. Konektivita
- Ethernet: Use the provided Ethernet cable for a stable wired network connection.
- Wi-Fi: Connect to wireless networks via the integrated 2.4 GHz and 5.0 GHz IEEE 802.11ac Wi-Fi.
- Bluetooth: Utilize Bluetooth 5.0 for connecting wireless peripherals such as keyboards, mice, or audio devices.
- HDMI: Connect up to two 4K displays using the micro-HDMI ports.
- USB: The Raspberry Pi 4 features two USB 2.0 ports and two USB 3.0 ports for various peripherals.
6. Údržba
Regular maintenance ensures the longevity and optimal performance of your Raspberry Pi 4:
- Čištění: Periodically clean the cooling fan and case vents to prevent dust buildup, which can hinder airflow and cooling efficiency. Use a soft brush or compressed air.
- Aktualizace softwaru: Regularly update your Raspberry Pi OS to ensure you have the latest features, security patches, and bug fixes. This can typically be done via the terminal using
sudo apt updateasudo apt full-upgrade. - Péče o microSD kartu: Avoid frequently removing and inserting the MicroSD card while the Raspberry Pi is powered on. Always shut down the system properly before removing the card to prevent data corruption.
7. Řešení problémů
Pokud narazíte na problémy, postupujte podle následujících běžných kroků pro řešení potíží:
- Žádný výstup na displej: Ensure HDMI cables are securely connected and your monitor is set to the correct input. Try a different HDMI cable or monitor.
- Problémy s napájením: Verify the USB-C power supply is correctly plugged into both the Raspberry Pi and a working power outlet. Ensure it is the recommended 5.1V 3A supply.
- Přehřívání: Check that the cooling fan is properly connected and spinning. Ensure the case vents are not blocked. If temperatures remain high, reduce workload or consider additional passive cooling.
- Operační systém se nespustí: Re-seat the MicroSD card. If the issue persists, try re-flashing the operating system onto the MicroSD card using a reliable tool like Raspberry Pi Imager.
- Periferní zařízení nebylo rozpoznáno: Try connecting the peripheral to a different USB port. Ensure drivers are installed if required by the operating system.
