Everything you need to know about Raspberry Pi

Raspberry Pi seems to be a continuous buzz in the technology sphere with almost 5-6 million Raspberry Pi living on this almighty earth already (As of 8 June 2015) and its ability to interact with the real world makes it a class apart.

Let’s explore it even more. Here we start:

Everything you need to know about Raspberry Pi?

What is Raspberry Pi?

Raspberry Pi is basically a small sized, single board compact computer, more precisely a credit/debit card sized computer. It can be plugged into a computer monitor or television (T.V).

It is a low-cost device developed by the Raspberry Pi foundation in order to enhance the computer based skills among all walks of life and to learn how to program in languages like Scratch and Python.

The Printed Circuit Board (PCB) of Raspberry Pi comes with an input and output connectivity with the hardware itself. It runs on Linux kernel based operating systems like *Raspbian, *Pidora etc.

History of Raspberry Pi?

Raspberry Pi was developed by Raspberry Pi Foundation, a registered educational charity, UK based firm.
The Foundation’s goal is to advance the education of adults and children, particularly in the field of computers, computer science, and related subjects.

The foundation of Raspberry Pi was laid in the year 2006 and its early concept was based on Atmel Atmega 644 microcontroller.

The computer is inspired by Acorn’s BBC Micro of 1981. Pi’s model A, model B and model B+ are references to the original models of the British educational BBC Micro computer, developed by Acorn Computers.

Specifications of Raspberry Pi 

The latest version Raspberry Pi 2 model B was released in February 2015.
It has :

A 900MHz quad-core ARM cortex-A7 CPU.
1 GB Ram.
4 USB ports.
40 *GPIO pins.
Full HDMI port.
Ethernet port.
Combined 3.5mm jack and composite audio.
Camera interface (CSI).
Display interface (DSI).
Micro SD card slot.
VideoCore IV 3D graphics core.
Apart from the latest version we also have 2 other versions
Raspberry Pi 1 model B+
Raspberry Pi 1 model A+.

The Raspberry Pi measures 85.60mm x 56mm x 21mm (or roughly 3.37″ x 2.21″ x 0.83″). It weighs 45g.

To what extent Raspberry Pi is capable of?

Raspberry Pi is built with a capability to interact with the outside world. It is equally capable as your desktop computer.

What purpose can Raspberry Pi be used for?

Raspberry Pi can be used for making real time projects just like detectors at weather stations, wirelessly controlling your stereo devices, in security systems and much more.

From where to get Raspberry Pi from?

One can buy it from www.amazon.com or  www.alliedelec.com or www.element14.comor you can directly buy it from their official website that is www.raspberrypi.org

The cost of Raspberry Pi

Raspberry Pi is a very affordable pocket sized device which is currently available in 3 variants :
Raspberry Pi 2 model B = 35$
Raspberry Pi 1 model B+  = 25$
Raspberry Pi 1 model A+ = 20$
exclusive of local taxes and shipping/handling fees.

Final Words :

Raspberry Pi is a very great initiative to provide low-cost computers to every walk of life by the Raspberry Pi foundation and seems to be very promising now and in the near future.

Moreover, it will widen the horizon of programming and will be a great step towards programming culture.

Do tell us what you guys think about this, Just leave a comment below and stay tuned.


*Raspbian: Raspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. An operating system is the set of basic programs and utilities that make your Raspberry Pi run. However, Raspbian provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi.

*Pidora: There was a spin of Fedora for the Raspberry Pi during the early days of its release, but that was quickly dropped in favor of Raspbian when it proved to be a bit slow and buggy.

*GPIO: General-purpose input/output (GPIO) is a generic pin on an integrated circuit whose behavior, including whether it is an input or output pin, can be controlled by the user at run time. GPIO pins have no special purpose defined and go unused by default.
