Lesson - 01 : Introduction to Raspberry Pi

About Raspberry Pi :

Raspberry Pi is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

It is a small single board computer, by connecting peripherals like Keyboard, mouse, display to the Raspberry Pi, it will act as a mini personal computer. It is used for real time Image/Video Processing, IoT based applications and Robotics applications. Raspberry Pi Foundation officially provides Debian based Raspbian OS. Also, they provide NOOBS OS for Raspberry Pi. We can install several Third-Party versions of OS like Ubuntu, RISC OS, Windows 10 IOT Core, etc.

It has got ARM based Broadcom Processor SoC along with on-chip GPU (Graphics Processing Unit).The CPU speed of Raspberry Pi varies from 700 MHz to 1.2 GHz. Also, it has on-board SDRAM(Synchronous dynamic random access memory) that ranges from 256 MB(Mega bytes) to 1 GB(Giga Bytes).

Different versions of Raspberry Pi

There are many generations of Raspberry Pi line: from Pi 1 to 4, and even a Pi 400. It has Model A and Model B of most generations. Model A is less expensive variant, and tends to have reduces RAM and fewer ports(such as USB and Ethernet).

• Pi 1 Model B (2012)

• Pi 1 Model A (2013)

• Pi 1 Model B+ (2014)

• Pi 1 Model A+ (2014)

• Pi 2 Model B (2015)

• Pi Zero (2015)

• Pi 3 Model B+ (2018)

• Pi 3 Model A+ (2019)

• Pi 4 Model A (2019)

• Pi 4 Model B (2020)

• Pi 400 (2021)
