The Raspberry PI is a low-cost, credit card size micro PC that developed by Raspberry PI Foundation in the UK. It launched back in 2012. The Aim of the Raspberry PI is to educate people in computing and programming skills. Raspberry Pi allows peoples to learn programming skills, build projects, and do home automation. For instance, you can start learning Scratch and Python using the Raspberry Pi. As mention previously, other than programming, it also used for browsing the internet, playing games, playing 4K videos, etc. The market prices of a Raspberry Pi is low as $35. There are various types of Raspberry Pi boards that exist in the current market.
Early 2012, Raspberry PI has a single-core 700 MHz CPU and 255 MB RAM, and it runs Linux. However, on 24 June 2019, Raspberry Pi launched a more powerful ARM Cortext A72 Based Processor. Which expands memory options of 1,2 or 4 GB LPDDR4 RAM. And you could buy it according to your requirements.
As we told earlier, Raspberry pi provides many advantages. For example, Raspberry Pi provides a set of GPIO (General Purpose Input/Output) pins. So, the input/ output pins enable to control of electronic components for physical computing. Just like a regular computer, you can connect a computer monitor, keyboard and mouse and start working on it. For example, you can install Linux or Windows lite version for regular operations.
Types of Raspberry PI boards exist in the market
As we mentioned above, from 2012 onward, they released different types of Raspberry Pi to the market.
- Raspberry Pi B
- Raspberry Pi A+
- Raspberry Pi 2
- Raspberry Pi Zero
- Raspberry Pi 3
- Raspberry Pi Zero W
- Raspberry Pi Zero WH
- Raspberry Pi 3 B +
- Raspberry Pi 3 Model A+
- Raspberry Pi 4 B

Components of Raspberry Pi
As mention previously, Raspberry Pi consists of many components. They are shown as follows in more detail. Furthermore, each type of Raspberry Pi boards can vary according to the model. However, below illustrate the basic components of Raspberry PI 3 Model B.
Which Raspberry Pi model is Best?
As we mention previously, there are a variety of Raspberry Pi Models and versions that exist in the market. Since there are many Raspberry Pi models, you can choose according to your project type. However, the Raspberry Pi has introduced the Raspberry Pi 4 recently that is good enough to use as a tiny PC, It is capable of an output of 4K video at 60Hz and to project dual monitors simultaneously.
At the first impression, you would think Raspberry Pi 4 looks similar to previous products of Raspberry Pi. However, when compared to the previous versions, there is much difference in Raspberry Pi 4. For instance, Raspberry Pi 4 uses USB-C for power connectors instead of USB micro-B.
