1. 이상view

The Raspberry Pi 4 Model B is a versatile single-board computer designed for a wide range of applications, from desktop computing to embedded projects. It features a powerful Broadcom BCM2711 Quad-core Cortex-A72 (ARM v8) 64-bit SoC running at 1.5GHz, offering enhanced processor speed, multimedia performance, memory, and connectivity compared to previous generations. This model comes with 1GB of LPDDR4-2400 SDRAM.

Key features include 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE, Gigabit Ethernet, two USB 3.0 ports, and two USB 2.0 ports. It also provides two micro-HDMI ports supporting up to 4Kp60, a 2-lane MIPI DSI display port, a 2-lane MIPI CSI camera port, and a 4-pole stereo audio and composite video port. Hardware video decoding (H.265 4Kp60, H.264 1080p60) and encoding (H.264 1080p30) are supported, along with OpenGL ES 3.0 graphics.

The device utilizes a Micro-SD card slot for operating system loading and data storage. Power is supplied via a 5V DC USB-C connector (minimum 3A) or via the GPIO header (minimum 3A). Power over Ethernet (PoE) is also supported with a separate PoE HAT.

4. 설정

The Raspberry Pi 4 Model B is designed for ease of use. This unit comes with a Samsung 32GB SD Card pre-loaded with Raspbian Buster (September 2019 update), requiring no initial setup for the operating system.

4.1 초기 연결

1. 마이크로 SD 카드 삽입: Gently insert the pre-loaded Samsung 32GB Micro-SD card into the Micro-SD card slot on the underside of the Raspberry Pi board until it clicks into place.
2. 디스플레이 연결: Connect one or two micro-HDMI cables from the Raspberry Pi to your monitor(s).
3. 주변기기 연결: 사용 가능한 USB 포트에 USB 키보드와 마우스를 연결하세요.
4. 네트워크 연결(선택 사항): For wired internet access, connect an Ethernet cable to the Gigabit Ethernet port. Wi-Fi is also available.
5. 전원 연결: Plug the 5V DC USB-C power supply (minimum 3A, not included) into the USB-C power input port. The Raspberry Pi will automatically power on and begin booting.

4.2 첫 번째 부팅

Upon connecting power, the Raspberry Pi will boot directly into the Raspbian Buster desktop environment. Follow any on-screen prompts for initial configuration, such as setting your locale and password.

5. 운영 체제

The recommended operating system for the Raspberry Pi is Raspbian, a Debian-based OS optimized for the Raspberry Pi hardware. Your included SD card comes with Raspbian Buster pre-installed.

5.1 기본 사용법

Once booted, you can interact with Raspbian Buster like any other desktop operating system. It includes a web browser, office suite, programming tools, and various utilities. Updates can be performed via the terminal using standard Debian commands (sudo apt update 그리고 sudo apt upgrade).

5.2 Raspberry Street Web 모니터링 플랫폼

This Raspberry Pi is ready to work with the Raspberry Street web monitoring platform. To register your Pi, navigate to the /home/raspberrystreet/ directory in the terminal and execute the command: java -jar rsiothub.jar (registration code). Obtain your specific registration code from the web dashboard of the Raspberry Street platform.

7. 유지관리

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

• 냉각: The Raspberry Pi 4 can generate significant heat under heavy load. Ensure adequate ventilation. If using a case, consider one with passive cooling (heat sinks) or active cooling (a fan) to prevent thermal throttling and maintain performance.
• 전원 공급 장치: Always use a high-quality 5V DC power supply with a minimum current rating of 3A, especially if connecting multiple USB peripherals.
• SD 카드 관리: Regularly back up your Micro-SD card. Avoid sudden power loss during write operations to prevent data corruption.
• 소프트웨어 업데이트: Keep your operating system and installed software up to date to benefit from the latest features, bug fixes, and security patches.

8. 문제 해결

If you encounter issues with your Raspberry Pi 4 Model B, consider these common troubleshooting steps:

• 부팅/화면 표시 안 됨:
  • Ensure the Micro-SD card is properly inserted and contains a valid operating system image.
  • Verify the power supply meets the minimum 5V 3A requirement.
  • Check micro-HDMI cable connections and ensure your monitor is set to the correct input.
• 과열:
  • If the device feels hot or performance degrades, ensure it has proper ventilation. Consider adding heat sinks or a fan.
• 주변 문제:
  • 주변기기를 다른 USB 포트에 연결해 보세요.
  • Ensure external USB devices have their own power supply if they draw significant current.
