Raspberry Pi Intro and comparison between 4 vs Pi 400

Raspberry Pi Intro and comparison between 4  vs Pi 400

Respberry Pi 4 vs Pi 400 differences and what’s coming next.
When mighty tech project needs reality an immediate wave come to the mind as “Respberry Pi”.

What is Respberry Pi:
A highly capable computer a revolutoin gadget which size like a deck of cards, and affordable as it cost just $35.With a bit of knowledge and ofcourse curiosity, one can hands on some of the following projects as free time builds:

  • A Retro Gaming Console.
  • Smart TV box.
  • A Desktop computer.
  • Home Automation.
  • LAMP Web Server.
  • Google Home on Raspberry Pi.
  • Ad Blocker

and the list go on and on…

History:

Raspberry Pi first commercial release was February 2012 and nobody belive that a computer available in just $25.
In 2012 Several boards revisions were made and finalized on Model A and Model B ( the most powerful at that time with Eithernet connectivity).
Right after 3 years in February 2015 Raspberry Pi Model B was released with significant power with new possibilities.

General components of RaspberryPi:

We shall walk though main components of Raspberry Pi present on every
Components of Raspberry Pi board:

  • Dimension.
  • System on Chip.
  • CPU.
  • GPU
  • SDRAM
  • USB 2.0 ports and 1 SoC on board USB.
  • MicroSD card ports.
  • Eithernet ports.
  • Audio IO.
  • GPIO Pins.
  • Video – Analog TV out.
  • Video HDMI port

Raspberry Pi 4 Model B vs Raspberry Pi 400:

The Raspberry Pi 4 Model B was launched in 2019 powered via USB-C port as the initial Raspberry Pi 4 board had a design flaw in the third-party e-marked USB cables that flaw was resolved in the 1.2 version also known as Rasberry Pi 4.

However Raspberry Pi 400 was launched in November 2020 , it is actually drived with the orginal Pi 4 but with the keyboard attached. Pi 400 has a slightly higher processor clocked at 1.8 GHz 

Lets see the Raspberry Pi 4 and Raspberry Pi 400 on side by side comparision:
