Brief information about Raspberry Pi
What is Raspberry Pi?
Raspberry Pi- a single-board computer, that is, various parts of the computer, which are usually located on separate boards, are presented here on one. In addition, this board has a relatively small size - about 8.5 * 5.5 cm.
The name of the product combines Raspberry - raspberry and Pi - the number of Pi. The image of a raspberry became the logo of the project.
Raspberry Pi sales began relatively recently - in early 2012, today it is the most popular platform in its field, more than 3.5 million copies of Raspberry Pi have already been sold.
How are Raspberry Pi and robots related?
The Raspberry Pi is often used as robot brain, home server or simply a computer.
Raspberry Pi in education
Initially, the project was created as an educational project, Raspberry Pi is great for learning the basics of electronics. There are many based on the Raspberry Pi. However, today his appointment has gone beyond educational.
What do you need to get started with Raspberry Pi?
To get started with the Raspberry Pi, in addition to the board itself, you will need:
- SD card from which you will boot the operating system; the manufacturer recommends using a card from 8 to 32 Gb, it actually works on smaller cards;
- monitor or TV with HDMI, DVI or RCA connectors (only for models A and B), and, accordingly, an HDMI-HDMI, HDMI-DVI or RCA-RCA cable, you can also use an HDMI-VGA converter;
- USB keyboard;
- USB mouse
- power cable or micro-USB battery
Raspberry Pi comes without an OS, you need to download it from the manufacturer's website and upload it to an SD card.
Raspberry Pi modifications
The Raspberry Pi comes in three flavors: A, A+, B, and B+. Model B is the most popular, B+ is gaining popularity as . The newest and cheapest, due to its price, will probably become a hit.

A step by step guide to getting your Raspberry Pi minicomputer up and running.
To start we need:
- Raspberry Pi
- USB keyboard
- USB mouse (if you are going to work in the visual shell)
- Micro USB power adapter for Raspberry Pi
- Monitor with HDMI input, or TV, or TV tuner with RCA connectors
- Win32DiskImager program for writing a system image to a USB flash drive
- Raspbian “wheezy” operating system image
- Card reader for reading SD/MMC/SDIO memory cards
SD/MMC/SDIO memory card from 2 to 32 GB (buy class 6 or 10 cards if possible)
HDMI cable for connecting to a monitor or RCA cable for connecting to a TV or TV tuner
If you have everything you need at hand, then continue.
Burning a Raspbian Image to a Memory Card for Raspberry Pi
To write a Raspbian system image to a memory card, you will need the Win32DiskImager program and the Raspbian “wheezy” image itself. Download them to your computer.
Now you have a USB flash drive with a burned Raspbian image ready to go.
Raspberry Pi connection
- Connect Memory Card to Raspberry Pi
- Plug in a USB keyboard (and USB mouse if needed)
- Turn on your monitor or TV (TV tuner)
- Connect Mini USB Power Adapter to Raspberry Pi
- Plug the Mini USB power adapter into a power outlet
Connect the HDMI cable to the monitor at one end, and the Raspberry Pi or RCA cable to the TV (TV tuner) and Raspberry Pi at the other end (only the yellow connector will be used in RCA)
When using a TV tuner as a monitor, you must select the composite input as the signal source.
Raspberry Pi setup
When you first boot your Raspberry Pi, you will see the Raspi-config menu 
If this does not happen, then type in the console the command sudo raspi-config
Through this menu we will be able to make the basic settings of our future system.
Consider the menu items that we will use:
You need to decide how much RAM you are willing to allocate to the GPU. When working in the console, 16 MB will be enough, but to watch the video in the graphical shell, you will have to sacrifice 64-128 MB. The selected values can only be: 16, 32, 64, 128 or 256.
For now, you can leave the default value, and then, if necessary, choose the option that suits you. Here we should take into account the fact that as the frequency increases, the energy consumption also increases. That is, your power supply must supply enough current for normal operation.
Setting a password for the "root" user on the Raspberry Pi
Type the command in the console sudo passwd root and enter the password twice.

Raspberry Pi Backup
Now we have a minimally configured working system with a small set of programs. So that in case of any unforeseen circumstances we do not have to repeat all of the above, we will make a backup of our data.
Leave all questions and additions in the comments. I would be grateful if you share the link to this article with your friends on social networks.
P.S. In the next article, I will describe the process of organizing remote access to the Raspberry Pi. SSH connection for console access and organization of remote access to files via SSH will be considered. We will also set up a local network.
If you are looking for a miniature, complete and quiet computer that can interact with the outside world, then the Raspberry Pi platform is perfect for you.
The scope of the Raspberry Pi is limited only by your knowledge and imagination.
Automate your home or use this tiny computer to create:
- a robot controlled via Wi-Fi or with computer vision,
- own game console
- home weather station
- tablet,
- security system with face recognition.
A computer the size of a bank card has on board the usual PC components: processor, RAM, HDMI connector, composite output, USB, Ethernet, Wi-Fi and Bluetooth.
The main advantage of the Raspberry Pi is the 40 General Purpose Input/Output (GPIO) pins. You can connect peripherals to them to interact with the outside world: actuators, any sensors and everything that runs on electricity.
The default operating system for the Raspberry Pi is Linux. It is installed on a microSD card, and that one - in a special slot on the board. If you don't know Linux, don't be intimidated. This computer is a great opportunity to figure everything out. Losing data or screwing up badly with the settings is not so scary, the image on the SD card can be restored in a matter of minutes. After that, feel free to continue experimenting!
Board version
The Raspberry Pi 3 Model B is the direct successor to the Raspberry Pi 2 Model B. The board is fully compatible with its predecessor but comes with better performance and new communication features:
- 64-bit quad-core ARM Cortex-A53 processor with a clock speed of 1.2 GHz on a Broadcom BCM2837 single-chip chip;
- built-in Wi-Fi 802.11n and Bluetooth 4.1.
In addition, the processor has an ARMv53 architecture, which means you can use your favorite operating system: Debian Wheezy, Ubuntu Mate, Fedora Remix, and even MS Windows 10 IoT.
Technical details
The Raspberry Pi 3 is equipped with a 64-bit quad-core ARM Cortex-A53 processor with a clock speed of 1.2 GHz per core as part of the Broadcom BCM2837 single-chip platform.
This chip provides a performance boost of 50-60% compared to the Raspberry Pi 2 and an almost tenfold advantage over the first Raspberry Pi. Thanks to this, the computer opens up even more opportunities for the "Internet of things" and embedded projects.
The Raspberry Pi 3 Model B has 1GB of RAM, but that memory is shared with the graphics subsystem.
The VideoCore IV® dual-core graphics processor supports OpenGL ES 2.0, OpenVG, MPEG-2, VC-1 standards and is capable of encoding, decoding and outputting Full HD video (1080p, 60 FPS, H.264 High-Profile).
Connecting peripherals
To connect a monitor or TV, use the composite video output or HDMI connector. Resolution ranges from 640×350 (EGA) to 1920×1200 (WUXGA) for HDMI. Composite output works in PAL and NTSC formats.
Speakers or headphones are connected via a standard 3.5 mm jack. Sound can also be transmitted via HDMI.
The Raspberry Pi 3 Model B provides 4 USB ports connected by an internal hub. Among other things, you can connect a keyboard and mouse to them.
To save CPU resources, the Raspberry Pi offers connections for standard modules through 15-pin slots:
- CSI-2 - for connecting a camera via the MIPI interface;
- DSI - for connecting a standard display.
The following are available as low-level interfaces:
- 40 general purpose I/O ports;
- UART (Serial);
- I²C/TWI;
- SPI with selector between two devices;
- power pins: 3.3 V, 5 V and ground.
The following interfaces are available for communication on the Raspberry Pi 3 Model B:
- Ethernet 10/100 Mbps with standard 8P8C (RJ45) output;
- Wi-Fi 802.11n and Bluetooth 4.1 provided by the Broadcom BCM43438 chip.
Food
The Raspberry Pi 3 is powered by a 5-volt adapter via the micro-USB connector or power pins. We recommend using a power supply with a current of at least 2 A in order to be able to connect more energy-intensive devices to USB ports.
There is no hardware power switch on the board. To turn on the computer, just connect the power cable. To turn off, use the regular functions of the operating system.
Dimensions
Board size: 85×54 mm. USB ports, Ethernet jack, HDMI, audio jack protrude beyond the marked frames by a few millimeters.
Software
Instead of the hard drive traditional for conventional computers, the Raspberry Pi uses a microSD flash card. It must be pre-prepared - an operating system should be installed on it. Having several flash cards, you can alternately use them, having received several isolated images of computers.
Flash card included not is included.

The Raspberry Pi Foundation has unveiled a new version of the Raspberry Pi mini computer without much hype, only announcing it on their blog. The popular gadget, like in the previous version, offers improved hardware, while the cost remains unchanged - only about 2,500 rubles ($35).
The most significant upgrade in the Raspberry Pi 3 is the 64-bit ARM Cortex-A53 processor, clocked at 1.2GHz. According to the manufacturer of the computer, it should be 10 times faster than the chip installed in the first version of the Raspberry Pi, and on average 50-60% faster than the Raspberry Pi 2 processor.
Our measurements confirmed the increase in performance (see graph below). In practice, the superiority of the new Pi 3 over its predecessors ranges from 2.5x (single-threaded applications) to 20x (video codecs). The powerful processor is complemented by gigabytes of RAM.
Two other innovations will also delight potential buyers and those who like to design computer systems with their own hands. For the first time ever, Pi 3 has built-in support for 802.11n wireless networks and Bluetooth 4.1. In addition, the new version is compatible with the previous ones, since the new Broadcomm-SoC (BCM2837) is based on the same architecture as the processors of the predecessor models.
Very economical PC
Otherwise, little has changed: slots, a 5V Micro-USB power connector, and a 32-bit Raspian Linux OS. In the coming months, the Raspberry Pi Foundation will consider moving to 64-bit Linux.
The increase in performance should slightly offset the increased power consumption of the mini PC: the Pi 3's power consumption under load is 0.3W higher than its predecessor. However, even with a measured value of 2.9W, the device is still extremely economical to use. To measure power consumption, we played a Full HD movie (1920x1080 pixels) using the OpenElec/Kodi media center during testing.
Visit www.raspberrypi.org for a variety of operating systems that can be used on your Pi 3. Image Noobs is the simplest option and has all the options you need to select from the start menu.
In order to use the mini PC as a full-fledged computer, you need to install Raspbian Jessie - a full-featured system with a desktop interface. Alternatively, you can use the first versions of the Android OS available for download on the Internet, which can be installed on the Raspberry.
If your Raspberry Pi 3 is going to be used in your living room, you should choose OpenElec. This is an OS based on the popular media center Kodi (formerly known as XBMC) with a gorgeous user interface, many great features and countless plugins that greatly expand the capabilities of the device.
During testing, the OpenElec system worked without failures, there were no “braking” menus. Playing a movie with a resolution of 1920x1080 pixels from a network resource also happened without problems: the movie starts up relatively quickly and plays without jerks and pauses for downloading. However, if your home network does not provide high speeds, it would be better to wait for the movie to preload.
To work with the Raspberry Pi 3 mini computer, you will need an external Micro-USB power supply. We recommend using a model with at least 2A @ 5V. You will also need at least an 8GB microSD card on which to install the OS. If you plan to work with a large number of files, it is better to install 128 GB of memory right away. And for maximum speed, a card of at least class 10 is recommended.
Windows 10: If you're more used to Microsoft's OS, you can install it on your Raspberry Pi 3 as well. Customized Windows 10
To launch the Raspberry Pi 3, Microsoft is offering an update in the form of a customized version of Windows 10 for mini PCs: Windows 10 IoT Core Insider Preview. Windows 10 IoT Core was designed specifically for the Internet of Things (IoT) and small devices with or without a display. Microsoft explains the benefits: this version of the OS provides rich Windows functionality, automatic updates, powerful security features, and can be managed with common administrator tools.
Raspberry Pi 3 is a significant step forward: now the computer performance is enough to assemble a compact, functional and powerful multimedia player. Thanks to the integrated Wi-Fi module and the specially designed OpenElec OS, the small “do-it-yourself computer” can become a powerful home entertainment machine.
However, users who have a Raspberry Pi 2 at their disposal do not have to upgrade to the new model. Only those who have just turned their attention to this topic or have used the first generation Raspberry Pi so far, in any case, should take the Raspberry Pi 3 Model B.
