Raspberry Pi
Introduction
• The Raspberry Pi is a credit-card sized
computer
• It can be plugged into your TV and a
keyboard, and can be used for many of
the things that your average desktop
does - spreadsheets, word-processing,
games and it also plays high-definition
video.
Introduction
• measuring
approximately
9cmx 5.5cm
History
•The Raspberry Pi is the work of the
Raspberry Pi
Foundation, a charitable organisation.
•UK registered charity (No. 1129409), May
2009
•It's supported by the University of
Cambridge
Computer Laboratory and tech firm
Broadcomm
Motivation
Computer science skills increasingly important
Decline in CS student numbers
Access to computers
Computers are the tool of the 21st century
Computer Science is concerned with much more
than simply being able to use a computer.
Children should understand how they work and
how to program them
What is Raspberry Pi?
• The Raspberry Pi is a fully featured
microcomputer
squashed onto a circuit board
measuring approximately 9cm x 5.5cm.
Why Raspberry Pi ?
Very Low Cost ($25 – Rs 1550/- for Model A & $35 –
Rs 2200/- for Model B/B+)
Great tool for Learning Programming, Computers &
Concepts of Embedded Linux, etc
Support for all Age Groups (School Children, College
Undergraduates, Professional Developers,
Programmers)
Supports & runs Free and Open Source Linux OS
Consumes less than 5W of Power
Supports Full HD Video Output (1080p), Multiple USB
Ports , etc
Fun to learn & explore. You are limited by your
imagination
Features
• Ultra low-cost (Model A $25,
Model B $35)
• Ultra low-power ~1W
• Credit-card sized, instant start-up
• Complete easy-to-program
computer
Features
• Provide a fun environment for
experimenting
with programming and electronics
• Inexpensive, simple, open and easy to
maintain computer for schools
• Fun computer for children to experiment
with at home(programming, robotics,
etc...)
Technology
• The Raspberry Pi has a Broadcom BCM2835
system on a chip ,which includes an
ARM1176JZF-S 700 MHz processor
• Video Core IV GPU
• originally shipped with 256 megabytes of
RAM, later upgraded to 512MB.
• It does not include a built-in hard disk , but
uses an SD card for booting and long-term
storage.
Hardware
• 10/100 BaseT Ethernet socket
• HDMI socket
• USB 2.0 socket
• RCA video socket
• SD card socket
• Powered from microUSB socket
• 3.5mm audio out jack
• Header footprint for camera connection
Power

(camera
interface)
SD Card Slot
(supports SD cards up to 32GB)
Storage
Operating System
• Linux on a bootable SD card
• Fedora
• Raspbian
• Debian
• ArchLinux ARM
How to make it work!
Programming
• By default, supporting Python as
the educational language.
• Any language which will compile
for ARMv6 can be used with the
Raspberry Pi.
Price
• Model A - $ 25
• Model B - $ 35
• Why so cheap ?
• SoC - System on a chip, a computer
on a single low voltage chip
• Linux OS
Applications
• Can be used for making super computers
Applications
Raspberry Pi Medical Device Input Shield
Applications
• Solar Raspberry Pi Power Pack
Applications
• Voice-Activated Coffee Machine
• Raspberry Pi Dynamic Bike Headlight
Prototype
Applications
It can make your Old TV in to a smart TV. (You can
play Videos, 3D Games, Music, Browse Internet and
much more.
• Raspberry Pi can Act as Full HD 1080p Media Player.
• Its a Mini Computer which just cost Rs.2,350/-
• You can connect a Monitor, Keyboard and Mouse
and use it as a normal computer.
• Its Graphics Capabilities is better than Apple
Products
Raspberry Pi Vs Akash
•Aakash is a low-cost tablet, and Raspberry Pi is
an ultra-cheap, customizable computer.
• Both tech innovations have education and
economy as their central goals.
• Aakash could fundamentally change the way
Indian
students and most of rural India connects with
the
Internet
Raspberry Pi Vs Akash
• The Raspberry Pi, directed at budding computer
engineers in the U.K., could alter the way the
next generation thinks about coding and building in
the computer universe.
• Both the Aakash and Raspberry Pi run on
ARMbased
processors, the British processor that runs
the vast majority of the world’s mobile phones,
smartphone and tablets.
Raspberry Pi Vs Akash
The first generation Aakash is said to run an ARM
11-based processor from Conexant running at
366Mhz.
• The Raspberry Pi uses an ARM 11-based
processor from Broadcom running at 700Mhz plus
a separate graphics processing unit.
• The processor in the Raspberry Pi has about
twice
the graphics performance of the iPhone 4S and
even bests Nvidia’s Tegra 2.
Raspberry Pi Vs Akash
• The Raspberry Pi can connect to a television or a
computer monitor via the commonly used
composite RCA and HDMI video interfaces.
• Akash tablet runs on an Android 2.2 OS.
• The Raspberry Pi computer will run a number of
Linux-based operating systems including Red Hat’s
Fedora as well as Debian, the basis for the popular
Ubuntu distribution, and Arch.
Disadvantages
• It does not have a Hard Disk associated with it
for permanent storage pf files,we have to connect
one
externally or have to use SD card for the purpose.
• The RAM is a POP package on top of the SoC, so
it’s not removable or swappable.
• There is no Real time clock associated with the
board.Adding an RTC is expensive. You can add
one yourself using the GPIO pins.
Future developments
● Tablet version
● Interesting low-cost screen
technologies emerging
● Brambles! (Networks of
Raspberries)
Raspberry Pi 2020
● Exploit process scaling and keep price
constant:
– 8 cores, improved GPU, 8GB main memory
– WiFi, camera, matchbox sized case
– holographic laser projector, virtual keyboard
– FPGA logic on main SoC, high speed links, ….
– < $25

Raspberry Pi Vs Akash • The Raspberry Pi, directed at budding computer engineers in the U.K., could alter the way the next generation thinks about coding and building in the computer universe. • Both the Aakash and Raspberry Pi run on ARMbased processors, the British processor that runs the vast majority of the world’s mobile phones, smartphone and tablets.
  • 29. Raspberry Pi Vs Akash The first generation Aakash is said to run an ARM 11-based processor from Conexant running at 366Mhz. • The Raspberry Pi uses an ARM 11-based processor from Broadcom running at 700Mhz plus a separate graphics processing unit. • The processor in the Raspberry Pi has about twice the graphics performance of the iPhone 4S and even bests Nvidia’s Tegra 2.
  • 30. Raspberry Pi Vs Akash • The Raspberry Pi can connect to a television or a computer monitor via the commonly used composite RCA and HDMI video interfaces. • Akash tablet runs on an Android 2.2 OS. • The Raspberry Pi computer will run a number of Linux-based operating systems including Red Hat’s Fedora as well as Debian, the basis for the popular Ubuntu distribution, and Arch.
  • 31. Disadvantages • It does not have a Hard Disk associated with it for permanent storage pf files,we have to connect one externally or have to use SD card for the purpose. • The RAM is a POP package on top of the SoC, so it’s not removable or swappable. • There is no Real time clock associated with the board.Adding an RTC is expensive. You can add one yourself using the GPIO pins.
  • 32. Future developments ● Tablet version ● Interesting low-cost screen technologies emerging ● Brambles! (Networks of Raspberries)
  • 33. Raspberry Pi 2020 ● Exploit process scaling and keep price constant: – 8 cores, improved GPU, 8GB main memory – WiFi, camera, matchbox sized case – holographic laser projector, virtual keyboard – FPGA logic on main SoC, high speed links, …. – < $25
