Description
Since its first introduction in 2012, the inexpensive series single board computer has sold over 25 million copies, making it an ideal companion for builders, developers, and computer enthusiasts alike. It's been utilized in robot brains, smart home hubs, media centers, retro gaming stations, networked AI cores, factory controls, and other places since then. The Raspberry Pi was created to allow creators to explore and learn about hardware and software development. It became one of the most popular computer brands over time. NASA has utilized the low-cost microprocessor to operate 3D printers and emulate old-school game consoles.
The RPi4 is similar in size and structure to the RPi3, except it includes twin HDMI outputs and improved USB and Ethernet performance. Wireless connection and Bluetooth 5.0 are two more significant characteristics. The Raspberry Pi 4 is expected to be available until January 2026.

How to Start with Raspberry pi 4 Model B:
Step 1: Go to Google or Bing and type raspberrypi.org into the search box.
Step 2: Go to the downloads area of the Raspberry Pi website.
Step 3: Then you'll see an option for Raspbian or Noobs (Raspbian is the operating system, and Noobs is an online OS downloader and installer). If you're a beginner, you can just download Raspbian manually because the installer can be confusing for new users, and online installation can sometimes be interrupted.
Step 4: You should now see three versions of Raspbian with various configurations; simply choose Raspbian Buster with desktop and recommended applications and download the ISO file.
Step 5: After you've downloaded the operating system, you'll need to download and install the following programs on your computer:
- 7-Zip File Extractor: http://www.7-zip.org/download.html
- SD Card Formatter: https://www.sdcard.org/downloads/formatter/
- Image Flashing Software: https://www.balena.io/etcher/
Step 6: Using a card reader, connect the MicroSD card to the PC and format it with the software described above.
Step 7: Using 7-Zip, extract the file you got from the Pi site by right-clicking on it. (Note: I've found that using WinRAR corrupts the file.)
Step 8: Now that you've extracted an ISO file, open the Balena etcher image flasher and drag and drop the picture into Select Image:
Step 9: Finally, pick the MicroSD card on which you want to install the OS and press the flash button.
Step 10: When the flashing is complete, remove the MicroSD card from the PC and insert it into the Raspberry Pi.
Step 11: Now that the OS portion is complete, connect the USB or Bluetooth Mouse Keyboard to the Raspberry Pi.
Step 12: Use a Micro HDMI to HDMI cable to connect the Pi to the display.
Step 13: Turn on the display first, then plug in the power adapter to turn on the Pi.
Thank you very much!! You've learned how to set up a Raspberry Pi 4 as a personal computer.
Ports: 40-pin GPIO header on the Raspberry Pi (fully backward compatible with previous boards)
4-pole stereo audio and a composite video connection are included in the package.
