Brief information about Raspberry Pi

What is Raspberry Pi?

Raspberry Pi– single-board computer, that is, various parts of the computer that are usually located on separate boards are presented here on one. In addition, this board has a relatively small size - approximately 8.5 * 5.5 cm.

The product name combines Raspberry - raspberry and Pi - the number Pi. The image of a raspberry became the project logo.

Sales of “raspberry” began relatively recently - at the beginning of 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?

Raspberry Pi is often used as robot brain, home server or simply computer.

Raspberry Pi in Education

The project was originally created as an educational project; Raspberry Pi is great for learning the basics of electronics. On Raspberry based Pi created a lot of . However, today his purpose has gone beyond just educational.

What do you need to get started with Raspberry Pi?

To get started with 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 connectors, DVI or RCA (models A and B only), and, accordingly, HDMI-HDMI cable, HDMI-DVI or RCA-RCA, you can also use an HDMI-VGA converter;
  • USB keyboard;
  • USB mouse
  • power cable or micro-USB battery

Raspberry Pi comes without an OS; it needs to be downloaded from the manufacturer's website and loaded onto an SD card.

Raspberry Pi modifications

Raspberry Pi is released in three variations: A, A+, B and B+. The most popular model is B, B+ is gaining popularity as . The newest and cheapest one will probably be a hit due to its price.

Online course "Raspberry Pi: first acquaintance"

Lesson 1. Device and OS installation Raspbian

The first lesson covers the Raspberry Pi device, installing the operating system Raspbian, connecting, turning on and off the Raspberry Pi.

Lesson 2. Connecting to the Internet, programs from the Pi Store and LibreOffice

In this lesson, you will set up a Raspberry Pi connection to the Internet via a LAN cable or WiFi adapter, learn how to download programs through the Pi Store catalog, in particular, install a free office suite LibreOffice.

Lesson 3. Console, apt-get utility, screenshots, remote control

In this tutorial, you will learn how to work with the Linux console, download programs using the apt-get utility, take screenshots using the scrot utility, and remotely control the Raspberry Pi using the VNC system.

Lesson 4. Working with GPIO, LED flashing, Python

In this tutorial, you will connect an LED and a button using the GPIO ports provided on the Raspberry Pi.

Raspberry Pi 3 can be called for real universal computer. Of course, you won’t be able to mine Bitcoin on it, and you won’t be able to play games with console graphics either. last generations He won’t be able to play, but he can handle a lot of other things well. Below, in turn, the main and most popular applications of the Raspberry Pi 3 will be discussed.

Multimedia capabilities of Raspberry Pi 3

The multimedia capabilities of the Raspberry Pi 3 are very great. In particular, based on "Raspberry" you can make multimedia center, game console or even all at once. As a result, with this single-board card you can access the following categories of entertainment on your TV with an HDMI port:

  • video in high resolution on YouTube or other hosting sites;
  • music on streaming services;
  • gaming streams on, for example, Twitch;
  • games developed for older consoles: NES, SNES, SEGA, etc.

To view and listen to multimedia content, you can either use a browser, or, even more convenient, install a special media player. The most functional and convenient of them is Kodi.

To turn Raspberry into a game console, you need to install emulators of the platforms you are interested in and order game Roms. This is done in a couple of tens of minutes. And it’s even easier and more convenient to install a special distribution, for example, Retro Pie or some other.

Development and work with documents on RPi

Of course, "Malina" is not the most powerful computer, which means - not The best decision for work. But if you wish, you can more or less comfortably view/edit some document or even write a script. Of course, it won’t work with heavy IDEs, but no one demands that from the RPi.

Also, using RPi3 you can “surf” the Internet or chat in instant messengers or social networks.

Server for every need from Raspberry Pi 3

Another option for using the Raspberry Pi 3 is to make a server out of it. So, it is enough to install LAMP or simply Apache and Myphpadmin on it, after which it will be possible to develop and test web projects in conditions of fairly limited resources.

The second option is to download and distribute from Raspberry Pi 3 torrent. This, of course, requires an external HDD, since memory cards and flash drives are not very suitable for these purposes, both due to speed limitations and small volume, and because they wear out quickly under intense loads.

Application of "Raspberry" in robotics and IoT

In IoT and robotics, the applications of RPi are almost limitless. From this device you can make, for example, a video surveillance camera, a small weather station, a car with remote control and much more. Thus, Raspberry Pi 3 is used in a car as a DVR. If desired, from this single-plate card you can even make mobile phone or smartphone. But it's worth doing either for the sake of experimentation or to show off to your friends/community. The fact is that the corresponding device will turn out to be at least quite bulky.

Of course, modules will be needed for these purposes. But there shouldn't be any problems buying them. There are many stores on the Internet that sell additional components for "Raspberry" at affordable prices.

Combining several RPi 3 into a cluster

Another way to use Raspberry Pi 3 is to combine several such devices into a cluster. This is a rather specific method of use that is not suitable for everyone.

To begin with, we should give a short and clear explanation of what a cluster is. IN general outline This term refers to a complex of homogeneous equipment (in in this case set of RPi) on which some task is executed in parallel.

There is no practical sense in making a cluster from Raspberry to implement something serious, since there are cheaper and more convenient solutions. Combining a Raspberry Pi 3 into a cluster is advisable mainly for training. Having several single-board devices, you can understand the features parallel computing or show how they work to a child (in fact, RPi was created for teaching children).

As you can see, there are a lot of interesting things you can do with the RPi 3. It is primarily useful for learning about computers. But it also allows you to implement very a large number of projects that can be used for work or leisure.

This single board computer, the first version of which was introduced in 2011, is gaining momentum and its popularity has exceeded all expectations. Today we’ll try to figure out what Raspberry Pi and single-board computers in general are, why they are needed, what are their advantages over traditional computers, what you need to start working with Raspberry Pi and where to buy Raspberry Pi. And then you will find a series of lessons on Raspberry Pi for beginners and interesting ideas on the use of the device in robots and robotics.

Raspberry Pi– single-board computer, that is, various parts of the computer that are usually located on separate boards are presented here on one.

The first project of the future Raspberry Pi was presented in 2011, industrial production began in 2012. The product name combines Raspberry - raspberry and Pi - the number Pi. The image of a raspberry became the project logo.

Initially, the project was created as an educational project; Raspberry Pi is great for learning the basics of electronics - everything is visible, accessible and not expensive. On the project website there is a significant detailed instructions and methods. The Raspberry Pi Foundation continually emphasizes the educational capabilities of the computer, in their official twitter you will find a huge number of young happy owners of the device and their achievements.

What are single board computers used for?

Single board computers are typically small in size, energy efficient, and relatively inexpensive. All this applies to the Raspberry Pi. Many users use Raspberry Pi as a server, because it consumes little power and is completely silent. Thanks to its small size, it can be built into various housings and used, for example, as the brain for a robot. Therefore, the project “Entertaining Robotics” turned to the consideration of this device. In general, with the Raspberry Pi you can do the bulk of everything that you do on a regular desktop computer, but with some specifics, mainly related to incompatibility with many operating systems.

The Raspberry Pi looks like this, the board size is similar to a credit card:

Raspberry Pi board

Today, Raspberry Pi is popular not only in education, but also among adults and quite serious guys who sometimes create such crazy projects - just some 64 Raspberry Pis, a few parts and a super-computer is ready!

Some technical details of Raspberry Pi

Raspberry Pi dimensions: 85.6x56x21 mm, weight 45 g.

RaspberryPi comes in two versions - A and B. Version B is by far the more popular.

Comparison of versions and main characteristics of Raspberry Pi:

  • Processor ARM11,Broadcom BCM2835,700 MHz;
  • RAM - 256 MB for A, 512 MB for B;
  • USB inputs/outputs - 1 for A, 2 for B;
  • SD input;
  • RCA output (“tulip”);
  • HDMI output;
  • Ethernet input/output - only B has it;
  • Audio output;
  • GPIO pins.

As you can see, the Raspberry Pi only has RAM. As permanent memory SD cards are expected to be used.

Cost and where to buy Raspberry Pi?

The official dealer and some other online stores in Russia sell model B for around 2300-2500 rubles + delivery.

The most economical way to buy a Raspberry Pi in Russia is still large Chinese online stores(I do exactly this myself).

As of this writing, Model B costs $44 on AliExpress and $49 on DealExtreme. Here and there free shipping. If you don’t have time to wait for a package from China, we recommend online stores and DESSY.

The prices of these stores are constantly changing, and some discounts and special offers appear. I myself recently ordered on DealExtreme for $54 and then it was Best offer. Therefore, if you are thinking about purchasing, then the current option on AliExpress is very profitable.

As for the work of the post office and customs, this time it took me a little less than a month from order to receipt. Previous parcels from China arrived within three weeks. Those. The timing is quite adequate.

The board was packaged in a cardboard branded box; the online store additionally packages it in a shockproof bag, so nothing should break on the road.

What else do you need to get started with Raspberry Pi?

To get started with 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, they actually work on smaller cards;
  • a monitor or TV with HDMI, DVI or RCA (“tulip”) connectors (VGA is not suitable), and, accordingly, an HDMI-HDMI, HDMI-DVI or RCA-RCA cable;
  • USB keyboard;
  • USB mouse.

I connected the Raspberry Pi to a 24-inch TV, it looks like this (the Raspberry Pi itself is highlighted in an oval):

Raspberry Pi connected to TV

The Raspberry Pi comes without an OS; it needs to be downloaded from the manufacturer’s website and loaded onto SD, which we will describe in more detail in the next article. They also sell SD cards with the OS already downloaded there. I don't see much point in this.

Good day to everyone, dear friends, enemies, acquaintances and comrades, readers, admirers and all sorts of other personalities. Today we'll look at Raspberry Pi Model 3B.

Here is another review of devices from our summer cycle, which we successfully continue on the pages of our portal "", project [ Sonikelf's Project's].

Located behind 4 port USB 2.0 and a hole for LAN-cord. By the way, this small miracle quite supportive WiFi And Bluetooth(which you will read about in the technical specifications below).

That's probably all there is to it with unpacking, because it's included in the package.. Only instructions, and even those are not very impressive. Well, you will also see photographs at the testing stage, impressions and conclusions.

Specifications, use and impressions of the Raspberry Pi Model 3 B

Let's now talk about what specifications this little scarf:

  • CPU: quad-core 1.2GHz ARM Cortex-A53 CPU (64-bit);
  • RAM: 1 GB LPDDR2 900 MHz;
  • Connectors: 4 pieces USB 2.0, MicroSD slot, HDMI, power socket, AV-out; GPIO (the same set of pins at the top), LAN (10/100 Mb/s);
  • Wireless technologies:Wi-Fi IEEE 802.11n (BCM43438 2.4 GHz) and Bluetooth 4.1;
  • Dimensions: 8.50 x 5.60 x 1.70 cm
  • Nutrition: Micro USB(yes, yes, charging from your mobile phone will do).

Such a powerful little “raspberry”, the size, as already mentioned, is approximately the size of credit card. Here are a few more promised photos of the assembly (including comparison with a standard lighter):

Then, in fact, the question probably arises: how to take off with this, that is, install the operating system, launch it and use it. And why, in general, might it be needed at all (apart from the fact that it full-fledged computer at a cost of barely 40$ ).

We will talk about use cases at the end of the article, but for now we will briefly show how to install the operating system, launch it and some screenshots of use.

How to run Raspberry Pi Model 3 B

In our example we will need:

  • MicroSD card with at least the volume 8 GB;
  • Program Win32 Disk Imager;
  • Distribution.

To which we point to the distribution downloaded in advance Ubuntu in format. img and press the button " Write"Of course we will receive a warning that all information from the card will be deleted:

If you saved everything from it valuable information, then you can calmly agree and then just wait for the end of the recording process.

Everyone runs and jumps quite successfully, but rather thoughtfully. The thoughtfulness is due to the fact that we used an old and low-speed MicroSD-card, and since the data carrier, as has been said more than once, is your computer, it would be good to use for Raspberry Pi Model Model 3 B a faster card, or use it for loading, say, external hard disk.

The application loaded from the card works quickly, cheerfully and cheerfully, which is not surprising given the gigabyte random access memory And 4 -x processor cores. For example, we played Minecraft, he’s certainly not that demanding, but still:

Oh, and yes, the sound HDMI it is transmitted perfectly and cleanly, which, however, is not particularly surprising for such a configuration.

Other impressions

Bluetooth works like a clock, WiFi also flies, in general everything is fine and surprisingly fast (except for the loading speed from MicroSD cards). Here's an example of a "waffle" with a standard stripped-down driver:

By the way, the raspberry is powered by MicroUSB, i.e. regular one will do Charger from your phone, tablet, or whatever you use:

Rumor has it that because of this, power consumption is simply monstrously small (measured in units, not tens of W), despite the overall power of the device as such.

What else can you say other than that everything works? Well, in general, probably a few words about the use and purposes for which “raspberry” is used.

WITH Raspberry Pi Model Model 3 B you can do anything, from ordinary (by the way, silent), small workstation for home/office and ending with server, torrent box, video broadcaster, controller smart home, 16 fun projects for your new Raspberry Pi ". The rest, if you want to get confused, you will find out yourself.

Plus, there are now a bunch of ready-made expansion modules for sale (although not as many as for Arduino) for “raspberries”, displays, etc., which you can buy, plug in and use, if you need it at all.

That’s probably all for now and it’s time to move on to the results.

Conclusions and results

Generally speaking, a computer, at a cost of about 35-40$ , such power, and even the size of a credit card, cannot be anything other than an indicator of technological progress.. And in general, such a miracle :)

That is, we mean that even if you are not a fan of all kinds of expansion cards and other handicrafts, then the “raspberry” is perfect for anyone as a work/home computer, fortunately, you can easily watch videos on it, surf the Internet, tinker with office programs and even play simple games.

For those who have golden hands and enough desire to do something with them, this “shawl” can provide enormous freedom to bring something useful to life, with minimal costs (both monetary and, often, time) .

Of the minuses, we can probably only mention the rumors that this “raspberry” model gets quite hot under constant, long and full load. Although we think that, if desired, this can be solved with a small radiator and hot melt glue, which now cost pennies.

In general, we can say that this is workhorse, good tool and just a nice toy.. Probably for everyone (by the way, it’s quite likely that we will do a series of articles on Raspberry, if there is time and money).

In a nutshell, perhaps something like this.
Let's move on to the afterword.

Afterword, discounts, coupons and where to buy

The device for review, as before, was carefully provided by a very good Chinese one, which pleases us in every possible way with its range and prices.

You guessed it, buy Raspberry Pi Model 3B You can have them now, for what you can use it. The price during this period is especially tasty, so hurry to grab it and take it to your home, as they say, urgently and urgently. And in general they have everything there.

As always, if you have any questions, thoughts, additions, etc., then welcome to comment on this post. As they say, hot on the trail and hands free
