What is Raspberry Pi ??


Introduction to Raspberry Pi




After watching above video you might have come to know that we are talking about some form of a computer, the Raspberry pi also known as Rpi.


Its basically designed to teach students or any interested person the power of computing.

  • A low cost, credit-card sized computer 
  • Plugs into a computer monitor or TV, can use a standard keyboard and mouse. 
  • It is a capable little device that enables people of all ages to explore computing 
  • 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.



Here is the latest model of Rpi Family....Big brother !!!

Raspberry Pi 3 B+ Board
The Raspberry Pi 3 Model B+ is the latest product in the Raspberry Pi 3 range.
  • Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC @ 1.4GHz 
  • 1GB LPDDR2 SDRAM 
  • 2.4GHz and 5GHz IEEE 802.11.b/g/n/ac wireless LAN, Bluetooth 4.2, BLE 
  • Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps) 
  • Extended 40-pin GPIO header 
  • Full-size HDMI 
  • 4 USB 2.0 ports 
  • CSI camera port for connecting a Raspberry Pi camera 
  • DSI display port for connecting a Raspberry Pi touchscreen display 
  • 4-pole stereo output and composite video port 
  • Micro SD port for loading your operating system and storing data 
  • 5V/2.5A DC power input 
  • Power-over-Ethernet (PoE) support (requires separate PoE HAT) 
Raspberry Pi is popularly used for Real time Image/Video Processing, IoT based applications, Robotics applications and many more creative stuffs.

Raspberry Pi is slower than laptop or desktop but is still a computer which can provide all the expected features or abilities, at a low power consumption.

Raspberry Pi Foundation officially provides Debian based Raspbian OS.



Raspbian OS is official Operating System available for free to use. This OS is efficiently optimized to use with Raspberry Pi. Raspbian have GUI which includes tools for Browsing, Python programming, office, games, etc.


We should use SD card (minimum 8 GB recommended) to store the OS (operating System).


Raspberry Pi is more than computer as it provides access to the on-chip hardware i.e. GPIOs (Header pins) for developing an application. By Programming GPIO, we can connect devices like LED, motors, sensors, etc and can control them too. Raspberry Pi also provides on-chip SPI, I2C, I2S and UART modules.


There are different versions of raspberry pi available as listed below:
  1. Raspberry Pi 1 Model A+
  2. Raspberry Pi 1 Model B+
  3. Raspberry Pi 2 Model B
  4. Raspberry Pi 3 Model B
  5. Raspberry Pi 3 Model B+
  6. Raspberry Pi Zero
  7. Raspberry Pi Zero W
