It is a long established fact that a reader will be distracted by the readable content of a page when l
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

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
