How to assemble raspberry pie 4B and install the system, I believe that many inexperienced people do not know what to do. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Since this is your first contact with raspberry pie, briefly introduce the raspberry pie and the steps to assemble and install the system.

What is raspberry pie?

Raspberry pie (Raspberry Pi), developed by the British Raspberry Pie Foundation, was originally designed to promote computer programming education in schools with low prices and open source software. Raspberry officially recommends that the operating system is debian-based raspbian, which can also be installed with systems such as ubuntu,fedora,windows lot. The hardware uses broadcom's ARM chip, which is so powerful that it wants to buy Qualcomm, and the memory is customized and welded to the motherboard. So far, raspberry pie has released nine models, the latest version is 4B, with 4-core cpu and up to 4G memory, support for usb 3.0 and Bluetooth 5.0. The following is a comparison of the hardware configurations of raspberry pie 3B+ and 4B (figure from Taobao seller):

There is currently no raspberry pie 4A or raspberry pie 4B +.

What can raspberry pie do?

According to official tutorials and common photo shows on the Internet, the main ways to play raspberry pie include:

Learning linux, programming

Personal websites, code hosting and other network services

Home nas/ Private Cloud

Offline / remote downloader

Combined with peripheral robots, cars, stereos, led, etc.

Intranet penetration, as well as dns, transparent proxy, etc.

The uses of raspberry pie that I think of at present are: personal code hosting, private cloud and intranet penetration.

What are the substitutes / competitions for raspberry pie?

According to personal understanding, the following products can (partially) replace raspberry pie:

Orange pie (orange pi). Domestic open source hardware that mimics raspberry pie is cheaper than raspberry pie, and the previous hardware configuration is higher than raspberry pie (4B configuration has caught up). The raspberry pie community is large, while the orange pie has less influence and play, so no one may be able to answer you when you encounter questions.

Arduino . Open source software and hardware platform, I feel that the main difference between raspberry pie and raspberry pie is that raspberry pie is a general programming microcomputer and Arduino is a special / industrial single-chip microcomputer.

A router that can brush firmware such as merlin. You read it right. It's the router. Before choosing raspberry pie, I also considered getting an Asustek router (the failed pole route is also quite suitable for my taste) to brush the Merlin system, which can achieve many of the desired functions.

This is a brief introduction to raspberry pie. Let's start the assembly and system installation of raspberry pie 4B.

Assemble the basic hardware of raspberry pie 4B

The official basic version of raspberry pie I bought from Taobao contains the following items:

Motherboard:

The front view of the motherboard, cpu, memory have been welded to the motherboard:

Official type C Power supply:

Official shell:

The shell bag contains the complimentary heat sink:

16GB SD card and a usb card reader (not photographed by the reader):

Raspberry pie 4B supports dual-screen 4k video, but the video interface has been changed to micro hdmi, so I bought a micro hdmi-to-hdmi adapter (8 yuan) from Goudong:

The above is all the hardware purchased online, of course, you have to take out the monitor, mouse and keyboard to do it.

Next, start assembling raspberry pie.

Assemble raspberry pie

To install the heat sink, first take a look at the layout of the raspberry pie 4B motherboard (picture from Taobao seller):

The seller gave five heat sinks, and I affixed them to the hardware: cpu, memory, usb management chip, wired network card, wireless network card. The effect picture after being pasted is:

The white piece in the heatsink is used for non-slip on the shell (similar to the four black circles in the four corners of the mouse), which is no longer shown here.

Unfortunately, the seller did not give the screw to fix the motherboard, so it may be easy to fall out if you put the motherboard directly on the shell.

Next, we introduce the steps to install the operating system for raspberry pie 4B.

Raspberry pie 4B installation system

Because the seller sent a blank SD card, the card was inserted into the motherboard, and there was nothing on the monitor after the power was turned on. For the raspberry pie to work properly, you must first install the operating system, which is officially recommended for beginners to install with NOOBS. The operation steps are as follows:

Insert the SD card into the card reader, which is connected to the usb port of the computer

Download NOOBS from the official website. Due to the domestic network environment, it is strongly recommended to download the offline version of NOOBS, do not use NOOBS Lite online installation!

Download and install SD card formatting software. Windows and other systems have the function of formatting SD cards, but the performance of such formatted cards is not good, so the official recommendation is to use the software provided by the SD Card Association.

Open the sd software, select the SD card and quick format, click "format" and it will be ready in a few seconds.

Unzip the downloaded NOOBS file to the root directory of the SD card

Pop up the card reader, remove the SD card from the reader and insert it into the raspberry pie motherboard

The raspberry pie is powered on, connected to the keyboard, mouse and monitor. Note: use the first one for the micro hdmi interface (the one near the power interface), otherwise the monitor may only show the following "rainbow" screen:

Select the system and the software to install in the pop-up interface. If you are offline, directly check the first "Raspbian [RECOMMANDDED]"; if you are a veteran, you can choose lightweight raspbian lite without graphical interface:

Next, NOOBS writes the system into the SD card, which will take a few minutes to hours depending on the installation mode and system functions.

Prompt to restart after installing the system

If you install the desktop version of raspbian, restart and automatically enter the desktop:

The setup boot pops up next. Before this, it is strongly recommended to open the terminal and change the official software source to Tsinghua Source. For specific operation, please refer to the official guide. After setting up the source, set the region, language, password, etc., in the boot interface, and then update the system.

At this point, the installation of the system is complete!
