Hardware and Materials

Raspberry Pi 3 Model B+ accessories: Case, power cord memory card, card reader display (with HDMI cable), mouse, keyboard

software

Exe, win32DiskImager.exe, Raspbian Buster with Desktop and Recommended Software

operation

  1. Download the system from the official website (the first), do not open the ladder will be a little slow, you can consider other download methods.

Consider packing the raspberry PI into a box while downloading the system (if you can’t get stuck, use scissors to cut off the puzzle bump on the box). 2. Use SDFormatter to format the SD card, decompress the system image, and use Win32DiskImager to burn the decompressed system into the formatted memory card. 3. Insert the memory card into the raspberry PI, connect it to the power, the correct state is PWR red constant, and ACT is yellow green flashing for a period of time. If ACT does not turn on or does not respond after connecting the monitor, it may be due to insufficient power supply/memory card is not formatted/system burn failure etc. I have been stuck here for a long time. 4. Connected with monitor, mouse, keyboard, can be used as a computer! (I don’t have an extra keyboard at hand at this point, so I’ll stop.)

Install on-screen keyboard

To install an on-screen keyboard, you need an Internet connection; In order to input wifi password, need to use the keyboard, endless loop, how to do?

  1. Open the built-in Chrminum browser, go to Settings — About Chrominum, and click on the blue font Open Source Software to go to the Credits page.

  2. Use these characters as character sets, copy the wifi password, and then connect to the Internet. If your wifi password is too complex to copy, start with a hotspot with a simple password.

  3. There are many ways to interact with a homepage. For example, you can click on any homepage link on the Credits page to go to Github and share words through Github. Sudo apt-get install matchbox-keyboard -y sudo apt-get install matchbox-keyboard -y

  4. Once the installation is complete, click on the raspberry icon — Accessories — Keyboard to see the on-screen Keyboard. The garbled characters of Matchbox can be solved by the method of this article, but his method is to change the text into English in essence. Maybe there is a better method, which will be explored in the future.
