One of the first major challenges when we acquired a Raspberry PI is to install raspbian to use the device.
Note : In this tutorial we have used a Raspberry PI 3 and the latest version of Raspbian available on the web.
What do we need?
We will need the following devices:
- a computer with SD card reader
- a microSD to SD card adapter
- a screen with DVI (or HDMI) input
- an HDMI-DVI cable (or HDMI-HDMI)
- a microUSB current charger of at least 2A and 5V
- an 8 Gb microSD card (better if it is class 10)
- a USB keyboard
- a USB mouse
- and a Raspberry PI of course
Devices to be taken into account (external microUSB battery,
Instead of using a microUSB power supply we can use a battery of about 8000 mAh or higher that has a 5V / 2A output.
Recommendation: RAVPower Charger External Battery .

NOOBS or Raspbian?
It is possible to install only Raspbian without NOOBS. But since NOOBS contains Raspian, and offers more ease when installing operating systems, we prefer to use NOOBS.
Now, it is possible to download Raspbian directly, unzip it and burn the image to the SD card. For this you can use Win32DiskImager for Windows or Etcher for Mac OS. Once done, we will have the card ready.
Raspbian comes complete with a lot of software for education, to learn to program and for general use.
For example it takes Python, Scratch, Sonic PI, Java, and Mathematica. Consult the tutorial to learn Python to make an introduction to this programming language.
There are two versions of Raspian , one more complete with Pixel that occupies about 4 Gb, and another that is called Raspbian Lite that does not have it.
Pixel is the graphical environment of Raspbian, it is the version of Desktop, something similar to a Windows operating system, ie with menus, windows, icons, wallpapers, etc ...
The version without the graphical environment would be something similar like the Windows System Symbol, that is to say a terminal of text without too many graphs. This option is usually for advanced users, who already have knowledge of Linux, and who want to create a web server project for example, where it is not necessary to have a graphical environment that consumes resources of the Raspberry.
As a practical example with another system we have set up a project with LibreELEC for a Media Center .
In these links you can buy the best books about Raspberry projects.
Installing the Raspbian
The next thing we will do is connect the external peripherals needed to use the Raspberry PI: the USB keyboard, the USB mouse, the HDMI-DVI cable to the monitor, and the power charger cable to the microUSB plug.
Then plug it into the power or external battery in our case.
We will see that the Raspbian system starts the system.
It will restart and we will see that the operating system starts for the first time with the graphic desktop.
For the users accustomed to linux, you will see that it is an ARM distribution of special linux for the Raspberry.
The user is pi and the raspberry password .
By the way, it comes with a graphical interface by default.
It also uses Debian's apt-get package system, which will be very familiar to Ubuntu users.
Here below I show you some pictures with the Raspbian screen.
Operating System Raspbian
In summary then, we have seen how to install the Raspbian operating system, a fairly simple task to perform, and that will take us a maximum of half an hour if we have the necessary devices.
