QUICK START GUIDE

Setting up your Raspberry Pi

Congratulations on your purchase from OOB and welcome to the exciting world

of the Raspberry Pi !

To setup your Raspberry Pi, you will typically need the following items:

1. MicroSD card (pre-loaded with NOOBS*)

2. Set of heat sinks to keep the Raspberry Pi running cool

3. Case to hold and protect your Raspberry Pi. Fans will also keep the Raspberry

Pi cool

4. USB MicroSD card readerfor use on your PC or Mac in case you need to

re-program the MicroSD card.

5. Micro-HDMI cable

6. 5V/3A DC Output MicroUSB power adapter

7. USB keyboard and mouse [Not Inclued]

8. HDMI monitor [Not Inclued]

9. Ethernet cable for connection to a wired network [Not Inclued*]

• NOOBS is designed to make it easy to select and install operating systems

for the Raspberry Piwithout having to worry about manually imaging your

MicroSD card.

• Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless

networking and Bluetooth.

The Raspberry Pi is a small computer ‒ a very small computer.

It consists of mostly the same parts as a standard desktop computer or

laptop. A central processing unit (CPU) acts as a brain, random access

memory (RAM) and long-term storage devices are used to hold data, a video

display shows you what is happening, and you interact with all of this using

mice,keyboards, joysticks, and other universal serial bus (USB) devices.

The Pi may be less powerful than your Windows PC or Macintosh, but it is still

impressive that it ﬁts all of this on a board only slightly larger than a credit

card.

Setting up your Raspberry Pi

Step 3 Basic Setup

Fitting a Heat Sink

When the components in a computer

system work hard, they generate heat.

And above a certain level, this heat can

reduce the lifespan of the components

or even break them altogether.

A Heatsink Armor Case is a carefully

designed block of metal that takes the heat away from the electronic component

and then passes it into the air surrounding the device.

There are three chips on a Raspberry Pi that can get very hot if the device is working

hard. Using 3 pieces thermal pads to touch the shell body for dissipating heat.

Setting up your Raspberry Pi

In the next chapter, you will learn about Raspberry Pi operating systems (in par-

ticularly, Raspbian Linux) and how to install them onto an SD card. This will com-

plete the set-up of the Pi. Inserting and Removing SD Cards It is likely that you

will need a memory card with more than 2 GB capacity, if you are intending to

run an operating system on the Pi. MicroSD cards are widely available and gener-

ally very cost-eﬀective.

To insert an SD card:

1. Shut down the Raspberry Pi from the button on the power cable.

2. Locate the SD card socket on the underside of the Pi's board.

3. When looking from above, the SD card's contacts should be facing up.

4. Gently, push the SD card into the socket.

Step 4 SD Cards

Connecting Power

Power is fed to the Pi through the Type-C socket or, if you have a suitable

connector, through the general purpose input output pins. However, provid-

ing power through the GPIO header pins bypasses the on-board protection cir-

cuitry that is designed to prevent damage to the device. For this reason, it

should only be attempted by people who are experienced in building electron-

ic circuits.

Connecting a Display

HDMI oﬀers a high-quality video and audio signal, and is the preferred way

of connecting all models of Raspberry Pi to a modern television. To connect a

high-deﬁnition television: Plug one end of an HDMI cable into the Raspberry

Pi's HDMI socket, and the other end into an HDMI input on your TV.

To remove the SD card: Gently pull the card out.

When inserting and removing SD cards in other computers, it is not always nec-

essary to turn oﬀ the device. However, as the memory card contains its operat-

ing system, the Pi may access it at any time. Removing the card while the Pi is

accessing it can corrupt data and, in extreme cases, may stop the card working

at all.

Raspbian and linux

An operating system (OS) is a unique type of application that you run on your

computer. It is an environment in which many other applications can run at the

same time, with a consistent user interface and sharing the same resources.

Microsoft Windows and Apple's Mac OS X are probably the two most well-known

operating systems, but there are others.

Raspbian is a Linux distribution that is based on Debian, another popular ver-

sion of Linux. It is designed for the Raspberry Pi and is the OS recommended

by the Raspberry Pi Foundation. Once you are familiar with Raspbian, you will

ﬁnd that you are able to use other varieties of Linux without much help.

Installing Raspbian

Raspberry Pi - AI & IoT

Installation of Raspbian with NOOBS

New out of Box Software (NOOBS) is a tool that you can run on your Raspberry

Pi, and it will help you install an OS. It stays on the SD card, even after the OS in-

stalled, and you can also use it to edit the Pi's main conﬁguration ﬁle or replace

the installed OS. The SD card supplied with your Pi already contains NOOBS.

Installing Raspbian

To install Raspbian, you will need to connect a keyboard, mouse, and display

to your Pi. First, ensure the Pi is completely oﬀ and unplugged, and then insert

the SD card into the Pi's memory card socket. Reconnect the power to your Pi.

The Pi will start and load the NOOBS tool.

To install Raspbian:

1. Click the box next to Raspbian.

2. On the toolbar, click Install. When the installation is complete, the Raspberry

Pi restarts and loads the raspi-conﬁg tool.

Raspbian's Desktop Environment

Raspbian's desktop is similar to Microsoft Windows and many of the ways that

you use it are the same. To interact with icons and buttons, click them with the

mouse. If you right-click an icon, Raspbian displays a context menu. The options

in a context menu only apply to the item that you clicked.

The desktop takes up most of the screen. This is where your programs will

appear when you start them. And if you save ﬁles to the /home/pi/Desktop

directory then you can see links to these ﬁles appear on the desktop.
