36. • The Raspberry Pi is a series of small single-board
computers developed in the United Kingdom by the
Raspberry Pi Foundation to promote the teaching of
basic computer science in schools and in developing
countries.
• The original model became far more popular than
anticipated, selling outside of its target market for uses
such as robotics.
• Over 5 million Raspberry Pis have been sold before
February 2015, making it the best-selling British
computer. By November 2016 they had sold 11 million
units.

39. • The first genera tion (Raspberry Pi 1 Model B) was released in
Februa ry 2012. It was followed by a simpler and inexpensive
model Model A.
• In 2014, the founda tion released a board with an improved
design in Raspberry Pi 1 Model B+. These boards are
approximately credit-card sized and represent the standard
mainline form-factor.
• Improved A+ and B+ models were released a year later. A
"compute module" was released inApril 2014 for embedded
applications, and a Raspberry Pi Zero with smaller size and
reduced input/outpu t (1/0 ) and general-purpose input/ou tpu t
(GPIO) capabilities was released in November 2015 for US$5.

40. • The Raspberry Pi 2 which added more RAM was released in
February 2015.
• Raspberry Pi 3 Model B released in February 2016, is
bundled with on-boa rd WiFi, Bluetooth and USB boot
capabilities.
• As o f January 2017, Raspberry Pi 3 Model B is the newest
mainline Raspberry Pi.
• Raspberry Pi boards are priced between US$5-35.
• As o f 28 February 2017, the Raspberry Pi Zero W was
launched, which is identical to the Raspberry Pi Zero, but
has the Wi-Fi and Bluetooth func tiona lity of the Raspberry
Pi 3 for US$10.

41. • All models feature a Broadcom system on a chip (SoC),which
includes anARM compatib le central processing unit (CPU) and an
on-chip graphics processing unit (GPU, aVideoCore IV).
• CPUspeed ranges from 700 MHz to 1.2 GHz for the Pi 3 and on
board memory range from 256 MB to 1 GB RAM.
• Secure Digital (SD) cardsare used to store the operating system and
program memory in either the SDHCor MicroSDHC sizes.

42. • Most boards have between one and four
USB SLOTS, HDMI AND COMPOSITE
VIDEO OUTPUT, AND A 3.5 MM
PHONO JA CK FOR AUDIO.
• Lower level outpu t is provided by a number
of GPIO pins which support common
protocols like 1
2c.
• The B-models have an 8P8C Ethernet port
and the Pi 3 and Pi Zero W have on board
Wi-Fi 802.11n and Bluetooth.

43. • The Foundation provides Raspbian, a Debian
based Linux distribution for download, as well
as third party Ubuntu, Windows 10 IOT Core,
RISC OS, and specialised media center
distributions.
• It promotes Python and Scratch as the main
programming language, with suppor t for many
other languages.
• The default firmware is closed source, while an
unofficial open source is available.

44. • This block diagram depicts ModelsA, B,A+, and B+. Model
A, A+, and the Pi Zero lack the Ethernet and USB hub
components.
• The Ethernet adapter is interna lly connected to an
additional USB port.
• In ModelA, A+, and the Pi Zero, the USB port is connected
directly to the system on a chip (SoC). On the Pi 1 Model
B+ and later models the USS/Ethernet chip contains a five
point USB hub, of which four ports are available, while the
Pi 1 Model B only provides two.
• On the Pi Zero, the USB port is also connected directly to
the Soc, but it uses a micro USB (OTG) port.

45. • The Broadcom BCM2835 Soc used in the first genera tion Raspberry
Pi is somewha t equivalent to the chip used in first modern
genera tion smartphones (its CPU is an o lder ARMv6 architecture),
which includes a 700 MHz ARM1 176JZF-S processor, VideoCore IV
graphics processing unit (GPU), and RAM.
• It has a level 1 (L1) cache of 16 KB and a level 2 (L2) cache of 128 KB.
The level 2 cache is used primaril
y by the GPU. The Soc is stacked
underneath the RAM chip, so only its edge is visib le.
• The Raspberry Pi 2 uses a Broadcom BCM2836 Soc with a 900 MHz
32-bit quad-core ARM Cortex-A7 processor, with 256 KB shared L2
cache.
• The Raspberry Pi 3 uses a Broadcom BCM2837 Soc with a 1.2 GHz
64-bit quad-core ARM Cortex-A53 processor, with 512 KB shared L2
cache

46. • The Raspberry Pi 3, with a quad-core Cortex-A53 processor,
is described as 10 times the performance of a Raspberry Pi
1.This was suggested to be highly dependent upon task
threading and instruction set use. Benchma rks showed the
Raspberry Pi 3 to be approximately 80% faster tha n the
Raspberry Pi 2 in parallelized tasks.
• Raspberry Pi 2 includes a quad-core Cortex-A? CPU running
at 900 MHz and 1 GB RAM. It is described as 4 -6 times more
powerful tha n its predecessor. The GPU is identica l to the
original. In parallelized benchma rks, the Raspberry Pi 2
could be up to 14 times faster tha n a Raspberry Pi 1 Model
B+.

47. • The Raspberry Pi 2 and the Raspberry Pi 3
have 1 GB of RAM.
• The Raspberry Pi Zero and Zero W have
512 MB of RAM.

48. • The Model A, A+ and Pi Zero have no Ethernet circuitry
and are commonly connected to a network using an
external user-supplied USB Ethernet or Wi-Fi adapter.
• On the Model B and B+ the Ethernet port is provided by a
built-in USB Ethernet adapter using the SMSC LAN9514
chip.
• The Raspberry Pi 3 and Pi Zero W (wireless) are equipped
with 2.4 GHz WiFi 802.11n (150 Mbit/s) and Bluetooth 4.1
(24 Mbit/s) based on Broadcom BCM43438 FullMAC chip
with no official support for Monitor mode but
implemented through unofficial firmware patching and
the Pi 3 also has a 10/100 Ethernet port.

49. • The Raspberry Pi may be operated with
any generic USB computer keyboard and
mouse.
• It may also be used with USB storage, USB
to MIDI converters, and virtua lly a ny other
device/componen t with USB capabilities.
• Other peripherals can be attached through
the various pins and connectors on the
surface of the Raspberry Pi.

50. • The video controller can emit standard modern TV
resolutions, such as HD and Full HD, and higher or
lower monitor resolutions and older standard CRT
TV resolutions.
• As shipped, it can emit these: 640x350 EGA;
640x480 VGA; 800x600 SVGA; 1024x768 XGA;
1280x720 720p HDTV; 1280x768 WXGA variant;
1280x800 WXGA variant; 1280x1024 SXGA;
1366x768 WXGA variant; 1400x1050 SXGA+;

• of FLOSS software company AdaCore as one
of the most exciting parts of the project.
• Community blogger Russell Davis said tha t
the community streng th allows the
Foundation to concentrate on documen tation
and teaching.
• The community developed a fanzine around
the platform called The MagPi which in 2015,
was handed over to the Raspberry Pi
Foundation by its volunteers to be continued
in-house.

56. • The MagPi is a free fanzine for users of the
Raspberry Pi computer.
• It was created by the community as an unofficial
volunteer produced Raspberry Pi publication
and in 2015 was handed over to the Raspberry
Pi Foundation to be run in-house as the official
Raspberry Pi magazine.
• It was launched in May 2012 and contains news,
projects and tutorials.

57. • In 2006, early concepts of the Raspberry Pi were based on the
Atmel ATmega644 microcontroller. Its schematics and PCB
layout are publicly available.

academics and computer enthusiasts to devise a computer to
inspire children.
• The computer is inspired byAcorn's BBC Micro of 1981.
• 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.
• The first ARM prototype version of the computer was mounted
in a package the same size as a USB memory stick. It had a USB
port on one end and an HDMI port on the other.

58. • The Foundation's goal was to offer two
versions, priced at US$25 and $35.
• They started accepting orders for the higher
priced Model B on 29 February 2012, the lower
cost Model A on 4 February 2013. and the even
lower cost (US$20) A+ on 10 November 2014.
