3. INTRODUCTION
 Project ara is a code name for an initiative by
google that aims to develop a free open hardware
platform for creating highly modular smartphones.
 User can customize device hardware and look.

4. INTRODUCTION (COTND..)
 The phone is designed to be a long term
sustainable product to customers.
 It is made up of swappable and replaceable parts.

5. HISTORY
 The project was originally headed by the advanced
technologies and projects (ATAP) team within
Motorola.
 In sep 2013 Dutch designer DAVE HEKKENS
announced the Modular phone concept
independently.

6. CONTD..
 Motorola publicly announced
project Ara on oct 29 2013.
 The project Ara was lead by Paul
Eremenko .
 Although Google had sold
Motorola to lenovo in jan 2014 but
Google kept ATAP and project Ara
which became Google Ara.

7. CORE COMPONENTS
 The Endoskeleton
 The module :
are of two types:
1.front module
2.rear module

8. ENDOSKELETON
 It consists of network circuits and
interfaces for modules.
 EPM used to attach modules.
 Endoskeleton has slots of
varying sizes.
 Made from aluminium.
 Comes in
three:mini;medium;jumbo.
 Water and dust proof.

9. MODULES
 Independent and interchangeable.
 Can be swapped between different
phones.
 Front modules includes interface to
the users.
 Rear modules provides back end
functionality.
 Dust and water proof.

10. EPM(ELECTRO PERMANENT MAGNET)
 The EPM has two selectable
states: the attach state and
release State, corresponding to
high and low levels of magnetic
force.
 Electrical power is needed to
Switch between the two states
only; the EPMs require no
sustained electrical power to
maintain either state.

11. CONTD...
 EPMs in the attach state provide sufficient magnetic
force to secure modules into their slots on the endo.
 EPMs in the release state provide a residual
magnetic force to prevent modules from falling out
unless the user deliberately removes the Module
from the endo.
 Users should be able to remove modules with
minimal effort when the EPM is in the release state.

12. ADVANTAGES
 Price
 Cheaper repairs
 Customization
 Increased life
 Battery life
 Support specilization
 Employement
 Reduce electronic waste

13. DISADVANTAGES
 Size of the phone
 Design
 Testing issue

14. CONCLUSION
 Modular phone is a good way to prevent e-waste.
 Modular phones more flexible as compared to the
existing phones.
 Multiple companies work on single product unlike
single company works on multiple products and
hence produce a good product to the customer.
