◆01: Detailed check of appearance and installed chips
The Raspberry Pi series is a single-board computer on which Linux can be installed, and is popular among PC enthusiasts as a device that can be used relatively easily to create IoT devices or as a small PC. The Raspberry Pi series is equipped with an SoC with performance that allows the Linux GUI to run smoothly, a wireless connection chip, a USB port, and other features, making it easy to use even for beginners. The Raspberry Pi 5, which was released in 2023, has a further enhanced SoC, and is equipped with PCIe connection and the I/O controller 'RP1' developed exclusively by the Raspberry Pi Foundation, significantly improving the specifications.

Below is an article that gives a detailed look at the appearance and ports of the Raspberry Pi 5. The article also includes close-up photos of the chips installed, so you can check what kind of configuration the device has before purchasing it.

◆02: Detailed explanation of OS installation procedures and Japanese localization procedures
You can install an Arm-compatible Linux distribution on the Raspberry Pi. The 'Raspberry Pi OS' developed by the Raspberry Pi Foundation is a very easy-to-use OS that comes with a GUI and various apps such as a browser. The following article explains the steps to install Raspberry Pi OS on the Raspberry Pi 5 and make it Japanese in an easy-to-understand manner even for beginners.

I've put together a simple guide for beginners on how to install an OS on the 'Raspberry Pi 5' and use it as a super-compact desktop PC - GIGAZINE



◆03: Check for interference with the original cooler
A genuine air-cooled cooler is available for the Raspberry Pi 5. However, the official website did not provide any information on which parts it cools or whether it interferes with the HAT, so I actually attached the genuine cooler to the Raspberry Pi 5 to check the cooling parts and the degree of interference.

I attached a genuine active cooler to the 'Raspberry Pi 5' and checked the cooling part and the interference with the HAT - GIGAZINE



◆04: Is an original cooler necessary? Check the temperature under high load
Many people may wonder, 'Does the fact that a genuine cooler is provided mean that it is prone to overheating?' or 'Does that mean that it is useless without a genuine cooler?' So, we checked the difference in temperature trends under high load when the genuine cooler was installed on the Raspberry Pi 5 and when it was not installed.

Is a genuine active cooler necessary for the Raspberry Pi 5? We tested how the temperature changes with and without the cooler - GIGAZINE



◆05: Which power supply is required for stable operation?
For the Raspberry Pi 5, it is recommended to use a power adapter that supports 5V/5A output. However, at the time of writing, the original Raspberry Pi power supply is not sold by Japanese distributors, so many people are probably wondering, 'What kind of power supply should I get?' In the following article, we connect an original power adapter that can output 5V/5A and a non-original power adapter that cannot output 5V/5A to verify the difference in system stability.

◆06: How to boot from external storage via USB
It is common for the Raspberry Pi series to use a microSD card as the boot disk, but the Raspberry Pi 5 also supports booting from storage connected to a USB port. You can check the steps to actually boot the system from a USB memory stick in the following article.

◆07: How to connect an M.2 SSD and boot the OS from it
The Raspberry Pi 5 supports PCIe connections, and you can connect an M.2 SSD and use it as a boot disk. However, when actually trying it, it was found that booting from an M.2 SSD requires some effort, and some M.2 SSDs cannot be used as boot disks due to compatibility issues. In the following article, you can check the steps to install the OS on an M.2 SSD and set it as a boot disk, available SSDs, and a speed comparison between SSDs and microSD cards.

◆08: How to connect various PCIe expansion cards and how to compile the kernel
The Raspberry Pi 5 supports PCIe connections, but when I tried to connect a USB port expansion card or a wired LAN port expansion card, I found that 'multiple conversion boards are required' and 'kernel compilation is required for some expansion cards.' Therefore, the following article provides a detailed summary of the procedure for connecting PCIe expansion cards and the procedure for compiling the kernel.

◆09: RTC function maintains time even when power is turned off
The Raspberry Pi 5 is equipped with an RTC function, and by connecting a backup battery, it can keep the correct time even when the power is cut off. You can check the procedure for connecting a backup battery to the Raspberry Pi 5 and the settings for charging the secondary battery for the backup battery in the following article.

◆10: The system is forced to shut down when exposed to strong light
While tinkering with the Raspberry Pi 5, I discovered that the system would shut down if a strong light was shone on a specific part on the back of the board. This could be a big problem depending on the application, so I've put together information in the following article, such as 'Which part will shut down if light is shone on?' and 'What happens to the log when the system shuts down?'

I have confirmed that the death flash phenomenon occurs when the 'Raspberry Pi 5' is forced to shut down when exposed to strong light, so I will share the details - GIGAZINE



◆11: Connect the graphics card and output the screen
'If the Raspberry Pi 5 supports PCIe connections, I should be able to connect a graphics board!' I thought, and after trying various things, I finally succeeded in getting the Raspberry Pi 5 to recognize the graphics board and output the screen. The following article provides a detailed explanation of the parts required to connect a graphics board and the steps for compiling the kernel.

Finally, I connected a graphics board to the Raspberry Pi 5 and succeeded in outputting the screen, so I summarized the steps - GIGAZINE



◆12: I tried connecting it to the 'DJI Power 1000' which can output 5V and 5A.
I was able to borrow the portable power supply 'DJI Power 1000' that can output 5V and 5A required by Raspberry Pi 5, so I tried to see if it was possible to actually supply power at 5V and 5A using multiple USB cables.

DJI's portable power supply 'DJI Power 1000' is said to support output of '5V / 5A', but I tried it with Raspberry Pi 5 to see if it was true - GIGAZINE
