Raspberry Pi : Introduction

Hello all,
The Raspberry Pi (RPi or RasPi) is a ultra low cost single board PC. This board has capacity to run various operating systems like Linux (Ubantu Mate, Raspbian etc), Windows 10 and some RTOS also. The primary aim behind creating such device is teaching programming to children but it has became popular for implementing various projects which require remote access support for various protocols and most of input - output devices.

There are many models available in market with different configuration. The Pi I am going to consider is Raspberry Pi 2. Specifications of this are as follows

• A 900MHz quad-core ARM Cortex-A7 CPU (by Broadcom)
• 1GB RAM 
• 4 USB ports 
• 40 GPIO pins 
• Full HDMI port 
• Ethernet port 
• Combined 3.5mm audio jack and composite video 
• Camera interface (CSI) 
• Display interface (DSI) 
• Micro SD card slot 
• VideoCore IV 3D graphics core
  

You can buy RPi online on Amazon, Sanpdeal or Flipkart, for near around 4000. Also there is one site www.crazypi.com where you can find all accessories required for RPi and their service is good.

Prerequisites for getting started with RPi are, RPi board, Memory Card (microSD, 8GB or 16 GB), micro USB 5V 2A power supply (It can be powered from PC using USB cable also).

In next post I will tell you how to start with RPi and installing Raspbian OS on it.

You can post any queries or suggestions in comments.
