What is Raspberry Pi v Created by Raspberry Pi Foundation v A credit-card sized computer that plugs into your TV and a keyboard v Model B was released in 2012 and Model A in early 2013 v It’s a capable little PC which can be used for many of the things that your desktop PC does PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 2/2

Why was Raspberry Pi Made? PNM Lab. , POSTECH v For education v Original measure of success: more CS students v But education-related efforts are rapidly spreading downward, aiming toward young children CS 490 K - Internet of Things (Io. T) 3/2

Raspberry Pi JTAG Video Audio USB GPIO Ethernet DSI Display Connector CSI Connector - Camera SD HDMI Power PNM Lab. , POSTECH CPU/GPU CS 490 K - Internet of Things (Io. T) 4/2

Two Models v Model B, version 1 Original $35 board (almost everybody's is this one) 256 MB RAM, all peripheral support v Model B, version 2 512 MB RAM v Model A $25 No Ethernet jack: networking via USB add-on 256 MB RAM PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 5/2

Raspberry Pi – Hardware v Processor and Memory Broadcom 2835 System On Chip • 32 bit ARM RISC CPU core (not x 86 compatible) • Videocore IV GPU Arm 11 hardware, Arm 6 architecture Default clock is 700 Mhz, but most will overclock to ~1 Ghz GPU is basically as powerful as what was on the original Xbox v Mass Storage: SD card Any SD card Kernel boots from SD card Easy to have root FS on other device PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 6/2

Raspberry Pi – Hardware v Video HDMI or (digital) DVI via cheap adaptor/cable Composite NTSC/PAL via RCA Wide range of resolutions • 640× 350 to 1920× 1200 v Audio Via HDMI Via 3. 5 mm stereo jack Stereo analog Output only PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 7/2

Raspberry Pi – Hardware v Networking 10/100 Mbps via RJ 45 on model B Wireless via USB add-on supported v USB Dual USB sockets on RPi model B, single on model A Expandable via regular or powered hubs PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 8/2

Raspberry Pi – Hardware v Power Primary power via micro. USB plug • A one amp cell charger works well, but you'll need two amps with a USB hard drive Model A about a quarter amp less PC USB port does not work Most Rpi boards have a current limiting fuse in the USB socket path • Highpower peripherals like HDD MUST use a powered USB hub • Fixed in rev 2 boards PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 9/2

Raspberry Pi – Hardware v General Purpose I/O (GPIO) 3. 3 volt logic via 26 pin header • NOT 5 volt or short tolerant Parallel I/O pins UART (Linux console support) I 2 C, SPI for peripherals No A/D, so no analog input Can do software-based PWM Libraries exist for interacting with the GPIO through several programming languages PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 10/

Raspberry Pi – Hardware v More I/O DSI LCD panel support CSI camera support JTAG Additional GPIO via other headers PNM Lab. , POSTECH CS 490 K - Internet of Things (Io. T) 11/
