The document discusses the history and features of the Raspberry Pi, a credit card-sized single board computer. It was developed by the Raspberry Pi Foundation in the UK to inspire teaching of basic computer science. The Raspberry Pi has an ARM processor, video core GPU, RAM, USB/HDMI ports and runs Linux. It is used for hobby projects, home automation, education and more. Models discussed include the A and B versions.

2. History:
 In 2006, early concepts of the Raspberry Pi were
based on the Atmel ATmega644 microcontroller. Its
schematics and PCB layout are publicly available.
 Foundation trustee Eben Upton assembled a
group of teachers, academics and computer
enthusiasts to devise a computer to inspire
children.
 The computer is inspired by Acorn's BBC Micro of
1981.

3.  The Model A, Model B and Model B+ names are
references to the original models of the British
educational BBC Micro computer, developed by
Acorn Computers.

4. What is a Raspberry Pi?
 Raspberry Pi is a credit-card sized single-board
computer designed and manufactured by the
Raspberry Pi foundation in the United
Kingdom.
 Raspberry Pi has an ARMv6 700 MHz single-core
processor, a VideoCore IV GPU and 512MB of RAM. it
uses an SD card for its operating system and data
storage.
 The Raspberry Pi officially supports Raspbian, a
lightweight linux OS based on Debian.

5. Introduction:

8. Types :
 In February 2013, the Raspberry Pi model A
was launched, It packed the same ARM
single-core processor and the GPU as model
B with half of the RAM capacity at 256MB.
 Priced at $25 per unit, the model A could be
regarded as the cheaper and less powerful
version of model B.
Model A:

9. Model B:
 In April 2012, the original Raspberry Pi, also known as
the model B, was launched.
 It offered an ARMv6 700 MHz single-core processor, a
VideoCore IV GPU and 512MB of RAM, all packed in a
credit card size board.
 The model B supported 26-pin GPIO and a SD card slot
for loading the operating system. Priced at $35 per unit.

10. Diagram & its Description:

11. Features:
 CPU: Quad-core 64-bit ARM Cortex A53 clocked at 1.2
GHz
 GPU: 400MHz Video Core IV multimedia
 Memory: 1GB LPDDR2-900 SDRAM (i.e. 900MHz)
 USB ports: 4
 Video outputs: HDMI, composite video (PAL and NTSC)
via 3.5 mm jack.
 Network: 10/100Mbps Ethernet and 802.11n Wireless
LAN

12.  This microcomputer is useful for small business that
run on a lower budget to use their product or to invent
new technology that embeds the product. Small
business owners can use it to automate any small task,
i.e.; such as using the Pi to run a website or use it as a
small database and media server.
 The product does not require user to have extensive
programming experience since it is aimed for the
younger generation to learn about programming. Python,
the programming language i.e.; Pi uses, is a smaller
amount complex than other languages available. It has
better code readability and allows the user to type
concepts using fewer number of lines. Python also has a
automatic memory management function.
Advantage:

13. Cont..
 The Raspberry Pi is perfect for adaptive technology
and it is able to display images or play videos i.e.; at
high-definition resolution to building systems such as
prototyping embedded systems. This product makes it
possible to build complex and effective at a cheaper
price.
 The product is efficient and i.e.; provides an ethical
alternative to small businesses. This small card sized
product i.e.; makes it easy to recycle and does not
release as much carbon dioxide emissions into the
environment

14. Disadvantages:
 It does not replace the computer, and the processor is
not as fast. It is a time consuming to download and
install software i.e.; unable to do any complex
multitasking.
 Not compatible with the other operating systems such
as Windows.

15. Cont..
 This is fit for those who want a gadget that they can
tailor to their own needs and tastes, i.e.; not for those
that just wants to urge a job done fast. Business owners
need to consider the extra hassle if is worth it.
 This product not be useful for bigger business that
already have big servers, i.e.; which would already do
everything that the Raspberry Pi does. So, it would not
be worth and it take time to get to put it together.

16. .
Conclusion :
The Raspberry Pi is a powerful little beast and a
great platform for building low-cost, but highly
capable, embedded systems. The interfaces built
into its GPIO connector make it easy to bolt on
modules using simple low-cost electronics and a bit
of configuration to create very functional and
flexible systems.
The inclusion of a dedicated camera interface and
networking interfaces give you everything you could
possible need for an Internet-connected home
security system.
