What is Raspberry PI? o Low cost, credit card sized computer o SOC (System on a chip) o Founded by Raspberry PI foundation o Low power consumption o Linux based 2

How it was founded?  Started in 2006  To make an affordable computer for students  First model was based on Atmel ATmega644 microcontroller 3

Features  Broadcom BCM2835 chip (A, B, B+, Zero)  BCM2836 (Pi 2)  ARM processors are used  Audio and Video output  HDMI  SD slot  USB and Ethernet ports 4

Features (cont…)  GPIO pins  Programming languages- Python (main), C, PERL etc  Can be added with I2C interface  Workable from -40 degree to 86 degree centigrade 5

How it works?  Like other computers  Boot OS 6

Raspberry Pi 1 model A+  Replaced original model A in 2014  More GPIO (40 pins)  One USB port  512MB RAM  SD slot  Low power- between 0.5W and 1W  Audio circuit incorporates low-noise power supply.  Model A+ is approximately 2cm shorter than the Model A  No Ethernet port  Cost $25 7

PI 2 model B+  4 USB 2.0 ports  Micro SD slot  10/100 Ethernet  512 MB RAM  1 GB RAM (PI 2 model B)  Quad core processor (PI 2 model B)  Cost $35 8

PI 3  1.2GHz 64-bit quad-core ARMv8 CPU  n Wireless LAN  Bluetooth 4.1  Bluetooth Low Energy (BLE)  Cost $35 9

PI Zero  1Ghz, Single-core CPU  512MB RAM  Mini HDMI and USB On-The-Go ports  Micro USB power  HAT-compatible 40-pin header  Composite video and reset headers  Cost $5 10

Implemented ideas  Home automation system  Drone  Game and video server  Voice controlled screen  Fortune telling machine  Security web cam  Robots  Multimedia player  Control sprinkler system 11
