Raspberry Pi asalka^{(original Raspberry Pi)} ahaa wuxuu ahaa mishiin yar oo soo jiidasho leh. Asal ahaan waxa loo abuuray hab la awoodi karo oo ay dhallinyaradu ku baran karaan in ay kood wax ku qoraan. Si buuxda^(Completely) loo heli karo oo aan lahayn wax khatar ah, marka la barbar dhigo ku dhex milanka kombiyuutarka qoyska. Ma abuuri kartid jiil cusub oo coders ah adigoon ku beerin rabitaanka ciyaarta iyo tinker.

Si kastaba ha ahaatee, kooxda dadka ka dambeysa qalabkaas ma qiyaasi karin waxa uu noqon doono. Pi ugu horeeyay wuxuu sidoo kale noqday gacaliyaha goobta sameeyay. Waxaan aragnay kumanaan mashruuc oo la qabsaday Pi si ay ugu dhaqmaan wax kasta oo aad qiyaasi karto.

Marka lagu daro Arduino , cirku runtii wuxuu ahaa xadka. Waxa ugu wanagsan, waxa ay ahayd kombayutarka ugu fiican ee qiima jaban ee ardayda lacagta caddaanka ah haysata. Gaar ahaan kuwa ku noolaa qaybo ka mid ah adduunka oo aan lahayn celceliska dakhliga si ay u helaan wax ka fiican. Ilaa $35, oo lagu daray kiiboodhka jaban iyo jiirka, waxaad u rogi kartaa TV kasta oo duug ah kombayutarka miiska.

Waxaan aragnay dhowr jiil oo cusub oo Pi tan iyo hadda, 2019, Raspberry Pi 4 wuxuu u bilaabmay fanfare yar. Haddi aad tahay taageere Pi-adag ama aad hadda bilowday inaad wax ka ogaato, waxaanu doonaynaa inaanu hoos u dhigno mishiinkan yar ee cajiibka ah si aad u ogaato inay kugu haboon tahay.

Hagaag, Laakiin waa^(is) maxay Raspberry Pi?

Si wax loo caddeeyo, dhammaan kombuyuutarrada Raspberry Pi waa kombiyuutarro-kumbuyuutar-ka-chip-ka ah oo iskood isku koobay. Ka fakar ^(Think)Raspberry Pi inuu yahay xudunta talefanka casriga ah ama tablet-ka halkaas oo ay tahay inaad ku xidho qalabkaaga wax gelinta iyo bandhigga. Waa kombuyuutar hoos loo dhigay qaybaha ugu muhiimsan ee uu ka kooban yahay, waxaana loo iibiyaa sidii hal wareeg oo wareeg ah.

Taasi waxa laga yaabaa inaanay u muuqan mid soo jiidasho leh marka la eego jaleecada hore, laakiin had iyo jeer waxay ahayd kiiska in jiil kasta oo Pi uu bixiyo kombuyuutar badan oo lacag ah. Ma aha oo kaliya sida xiisaha, laakiin sida qalab wax ku ool ah oo loogu talagalay xaalado badan oo kala duwan. Guntii iyo gabagabadii waxa weeye in Raspberry Pi uu yahay kumbiyuutar aan qaali ahayn oo lagu sameeyay qaybo ka mid ah talefanka gacanta oo aad uga badan qalabka lagu ciyaaro.

Marka, Pi 4 ma anigaa ii ah?

Iyadoo Raspberry Pi uu yahay mashiin yar oo cajiib ah, maahan doorashada saxda ah ee qof walba. Waxaa jira laba su'aalood oo aasaasi ah oo aad u baahan tahay inaad ka jawaabto ka hor inta aanad dufin hal.

Marka hore^(First) , ujeedada aad u malaynayso qalabku ma ku dhici doonaa awoodiisa xisaabinta? Pi 4 wuxuu leeyahay awood faras badan oo ka badan qaabkii hore. Markaa jawaabtu waxay ahaan kartaa "maya" waagii hore, laakiin "haa" hadda. Waxaan ka wada hadli doonaa sida saxda ah inta ay le'eg tahay awoodda mashiinkan cusub wax yar ka dib maqaalkan

Su'aasha labaad ee aad u baahan tahay inaad ka jawaabto waa haddii software-ka aad rabto inaad ku shaqeyso uu ku shaqeyn doono Pi mabda'a ahaan. Pi wuxuu wataa nooc Linux ah, oo si gaar ah loogu ururiyay naqshadaha processor-ka ARM .

Inta badan tani waxay ka dhigan tahay in codsigaagu u baahan yahay inuu ka shaqeeyo Linux oo^{(and )} uu ku shaqeeyo nooca ARM halkaas. Iyada oo leh awoodda habaynta xaddidan ee xitaa Pi cusub, kuma talineyno ku dayashada qaab dhismeedka x86 ee caanka ah. Waxay u badan tahay inay fiicnaan lahayd inaad doorato beddelka.

Maxaan u Baahan Yahay Marka^(Addition) lagu daro Pi 4 ?

Markaad iibsato Pi 4 , waxa kaliya ee aad helayso waa sabuurada kumbuyuutarka laftiisa. Awoodda, waxaad isticmaali kartaa fiilada USB-C ee caadiga ah oo ku xiran isha tamarta USB ee caadiga ah. ^(USB)Tani waxay noqon kartaa deked USB ah oo ku taal TV-gaaga ama dallad telefoon oo duug ah. Ilaa inta ay ka soo saari karto 5V at 3A waad fiicnaan doontaa.

Aasaaska Pi ayaa^{(Pi Foundation)} ku talinaysa 15.3W USB-C dabaylaha gidaarka ee rasmiga ah. Pi 4 wuxuu leeyahay shuruudo koronto oo aad u sarreeya, marka waa inaad laba jeer hubisaa. In kasta oo laga yaabo in ay ku socoto awood yar, isla marka dalabka habbaynta soo baxdo ama meelo badan oo durugsan la isku xidho, waxaa jiri kara xasillooni darro.

Waxa kale oo aad u baahan tahay muraayad lagu xidhi karo micro-HDMI. Taas oo la macno ah inay u badan tahay inaad hesho adabtarada.

Pi ma laha kayd labaad oo lagu dhex dhisay, taas oo macnaheedu yahay iibsashada ama dib u warshadaynta kaarka SD. Waxaad la soo qaadan kartaa mid horay loo raray oo ay la socoto Pi 4 ama waxaad ku soo dejisan kartaa software-ka kaadh aad hore u lahayd adigoo isticmaalaya kombiyuutar kale.

Pi 4 wuxuu u yimaadaa sida loox qaawan. Waa inaad keentaa kiiskaaga haddii aad mid u baahan tahay. Tani waa ikhtiyaari oo dad badan ayaa isticmaala kombuyuutarkooda Pi iyada oo aan wax kiis ah jirin haba yaraatee. Waxaad iibsan kartaa kiis rasmi ah, mid 3D daabacan kartaa ama wax uun ku samee gacanta. Doorashooyinku waa kuwo aan dhammaad lahayn.

Maxaa ka cusub Pi 4?

Tani waa mid ka mid ah cusboonaysiinta ugu dhammaystiran ee Pi waligeed. In kasta oo jiilkii koowaad ee Pi uu ahaa wax-soo-saar caqli-gal ah, Pi 4 wuxuu leeyahay astaamo u dhigma oo la siman kombuyuutar kasta oo caadi ah.

Waxaad dooran kartaa inta u dhaxaysa saddex qaabaynta RAM : 1GB, 2GB ama 4GB. Inkastoo aadan dib u cusbooneysiin karin, sidaas darteed doorashada saxda ah waa muhiim.

Waxaa jira laba dekedood oo micro HDMI ah, oo taageero u leh laba bandhig oo 4K ah. Afar dekedood oo USB ah, oo laba ka mid ah ay yihiin USB 3 , ayaa bixiya wax ka badan qol ku filan oo loogu talagalay qaybaha. Gaar ahaan maadaama uu Pi 4 leeyahay Wifi iyo Bluetooth lagu dhex dhisay. Moodaaladii hore waxay u baahdeen dongle USB ah hawlahan. Wired Ethernet waa mid jira oo sax ah sidii hore sidoo kale.

Xiddiga weyn ee Pi-gan cusub waa shaki la'aan nidaamka quad-core Cortex A72 ee chip. Chip xudunta cusub waxa uu u dhexeeyaa saddex ilaa afar jeer sida ugu dhakhsaha badan ee Pi 3 . Iyada oo ku xidhan hawsha gaarka ah. Tani waxay dhigaysaa heer uu Pi 4 dhab ahaantii loo isticmaali karo hawlaha caadiga ah ee maalinlaha ah^{(typical daily desktop tasks)} .

Arrinta Software-ka

Waxaad ku shuban kartaa wax kasta oo ku saabsan nidaamka hawlgalka iyo codsiyada ka shaqeeya dhismaha ARM ee Pi 4 , laakiin dadka intooda badan waxay rabaan Raspbian , nooc gaar ah oo Debian Linux ah oo loogu talagalay Raspberry Pi .

Nasiib darro, waqtiga qorista, Raspbian diyaar uma aha dib u eegistii ugu dambeysay ee qalabka. Markaa isticmaaleyaasha qaar ee rajaynaya inay socodsiiyaan emulators-yada gaarka ah ama codsiyada kale ee caanka ah ee Pi ayaa laga yaabaa inay rabaan inay joojiyaan ilaa horumariyayaashu ka shaqeynayaan mashaariicdaas ay dhammeeyaan kafeega dhammaan kinks.

Miyaan iibsadaa Pi duug ah?

Iyadoo Raspberry Pi 4 -kan cusub uu aad uga dhaqso badan yahay qaabkii hore, ma ku fikiraysaa inaad iibsato nooc duug ah? Taasi waa su'aal wanaagsan, gaar ahaan maadaama Pi-ga cusub uu la mid yahay qiimaha furitaanka sidii moodooyinkii hore. Markaa haddii aad diyaar u tahay inaad bixiso qiimaha lagu weydiinayo Pi 4 markaas si cad ayay u fiican tahay lacagta.

Taas macnaheedu maaha in dhammaan jiilka saddexaad iyo aaladaha hore ay si lama filaan ah faa'iido u lahayn. Haddii aad ka heli karto qiimo aad uga hooseeya kan Pi 4 , weli waxaa jira waxyaabo badan oo aad sameyn karto. Hadda waxa sidoo kale jira maktabad software oo aad u bisil oo loogu talagalay moodooyinkii hore. Filo kombiyuutaro badan oo Pi ah oo jaban oo la isticmaalay inay iib u baxaan mustaqbalka dhow.

Hayso Pi-gaaga oo sidoo kale Cun

Waa wax lala yaabo in aad hadda ku heli karto kombuyuutar miiska heerka gelitaanka ah oo dhan $35! Waxay u egtahay in ay tahay in la qabto xoogaa, laakiin runtu waxay tahay in tignoolajiyada kombuyuutarku ay horumartay ilaa heer kombiyuutarada intooda badani ay ka awood badan yihiin inta badan isticmaalayaasha u baahan yihiin. Raspberry Pi ugu dambeeyay ayaa ah tusaalaha ugu dambeeya ee kumbuyuutarka " ku filan ". ^{(good enough)}Waxay yiraahdeen ma haysan kartid keeggaaga oo aad sidoo kale cuntid, laakiin si cad taasi lama xisaabinayo marka ay timaado Pi.

What You Need to Know About the Raspberry Pi 4

The original Raspberry Pi was a fascinating little machine. It was originally created as an affordable system young people could learn to code on. Completely accessible and posing no risks, compared to messing around with the family computer. You can’t create a new generation of coders without instilling the urge to play and tinker.

However, the team of people behind that device could not have imagined what it would become. The first Pi also became the darling of the maker scene. We saw thousands of projects that adapted the Pi to act as anything you can imagine.

Combined with an Arduino, the sky really was the limit. Best of all, it was the perfect low-cost computer for cash-strapped students. Especially those who lived in parts of the world that lacked the average income to afford anything better. For about $35, plus a cheap keyboard and mouse, you could turn any old TV into a desktop PC.

We’ve seen several new generations of Pi since and now, in 2019, the Raspberry Pi 4 has launched to no small fanfare. Whether you are a die-hard Pi fan or have only started being curious recently, we’re going to demystify this wonderful little machine so that you know if it’s right for you.

OK, But What is a Raspberry Pi?

To make things crystal clear, all Raspberry Pi computers are self-contained system-on-a-chip computers. Think of a Raspberry Pi as being the guts of a smartphone or tablet where you have to connect your own input devices and display. It’s a computer stripped down to its most essential components, sold as a single circuit board.

That might not sound too appealing at first glance, but it’s always been the case that each generation of Pi offers a lot of computer for the money. Not just as a curiosity, but as a practical tool for many different scenarios. The bottom line is that the Raspberry Pi is an inexpensive computer made with mobile phone components that’s far more than a toy.

So, Is The Pi 4 For Me?

While the Raspberry Pi is a phenomenal little machine, it’s not the right choice for everyone. There are two primary questions you need to answer before shelling out for one.

First of all, will the purpose you envision for the device fall within its computing abilities? The Pi 4 has a lot more horsepower than the previous model. So the answer might have been “no” in the past, but “yes” now. We’ll discuss exactly how much more powerful this new machine is a little later in this article

The second question you need to answer is whether the software you want to run will work on the Pi in principle. The Pi runs a form of Linux, specially compiled for the ARM processor architecture.

In most cases this means your application needs to work in Linux and work in the ARM version at that. With the limited processing power of even the newest Pi, we wouldn’t recommend emulating the more common x86 architecture. It would probably be better to opt for an alternative.

What Will I Need in Addition to the Pi 4?

When you buy the Pi 4, all you get is the computer board itself. For power, you can use a standard USB-C cable connected to a normal USB power source. This can be the USB port on your TV or an old phone charger. As long as it can output 5V at 3A you’ll be OK.

The Pi Foundation recommends their own official 15.3W USB-C wall charger. The Pi 4 has significantly higher power requirements, so you will have to double check. While it may run with less power, as soon as the processing demands pick up or too many peripherals are connected, there could be instability.

You also need a display that can be connected to micro-HDMI. Which means you’ll probably have to get an adapter.

The Pi Doesn’t have secondary storage built in, which means buying or recycling an SD card. You can pick up a preloaded one along with your Pi 4 or just download the software to a card you already own using another computer.

The Pi 4 comes just as a naked board. You’ll have to provide your own case if you need one. This is optional and many people use their Pi computers with no case at all. You can buy an official case, have one 3D printed or just make something by hand. The options are endless.

What’s New in The Pi 4?

This is one of the most comprehensive updates to the Pi ever. While the first-generation Pi was a product of smart compromises, the Pi 4 has a feature set that puts in on par with any typical computer.

You can choose between three RAM configurations: 1GB, 2GB or 4GB. Although you can’t upgrade later, so choosing the right option is crucial.

There are two micro HDMI ports, with support for two 4K displays. Four USB ports, two of which are USB 3, provide more than enough room for peripherals. Especially since the Pi 4 has Wifi and Bluetooth built in. Previous models required a USB dongle for these functions. Wired Ethernet is present and correct as before as well.

The big star of this new Pi is without a doubt the quad-core Cortex A72 system on a chip. This new core chip is between three and four times as fast as the Pi 3. Depending on the specific task. This puts it’s it at a level where the Pi 4 could actually be used for typical daily desktop tasks.

The Software Issue

You can load just about any operating system and applications that work on the ARM architecture on the Pi 4, but most people are going to want Raspbian, a special version of Debian Linux designed for the Raspberry Pi.

Unfortunately, at the time of writing, Raspbian isn’t quite ready for the latest hardware revision. So some users who are hoping to run particular game emulators or other popular Pi applications might want to hold off until the developers working on those projects finish ironing out all the kinks.

Should I Buy An Older Pi?

With this new Raspberry Pi 4 being so much faster than the previous model, should you consider buying an older model?  That’s a good question, especially since the new Pi is the same launch price as previous models. So if you are willing to pay the asking price for the Pi 4 then clearly it’s the best for the money.

That doesn’t mean all the third-generation and older devices are suddenly useless. If you can find them at significantly lower prices than that of a Pi 4, there’s still plenty of things you can do. Right now there’s also a much more mature software library for the older models. Expect many inexpensive used Pi computers to go up for sale in the near future.

Have Your Pi and Eat It Too

It’s pretty astounding that you can now get an entry-level desktop computer for the sum of $35! It almost seems like there has to be some catch, but the truth is that computer technology has advanced to the point that most computers are more powerful than most users need them to be. The latest Raspberry Pi is the ultimate example of a “good enough” computer. They say you can’t have your cake and eat it too, but clearly that doesn’t count when it comes to Pi.
