Qhov kev hloov pauv tseem ceeb tshaj plaws hauv Raspberry Pi 3 yog 64-ntsis platform tshiab los ntawm Broadcom nrog ntau zaus (1200 MHz piv rau 900 MHz). Hmoov tsis zoo, thaum tsuas yog qhov nce zaus muaj rau cov neeg siv, 64-ntsis cov lus qhia tsis tau siv. Txij li thaum cov tub ntxhais ntawm ib lub chips ib leeg tseem ua rau ntawm ARMv7 architecture, tsis tas yuav tsum muaj cov tub ntxhais sib cais - koj tuaj yeem siv lub kaw lus los ntawm Raspberry Pi 2 (los ntawm thawj version nws yuav tsis ua haujlwm: nws yog tsim los ntawm ARMv6). Txhawm rau kom nkag siab qhov ua tau zoo: cov txheej txheem ua raws li tib lub hauv paus Cortex-A53 tau teeb tsa hauv qib nkag thiab nruab nrab ntawm cov smartphones.

Lwm qhov tseem ceeb rau cov neeg siv yog qhov tshwm sim ntawm wireless interfaces soldered ntawm lub rooj tsavxwm. Qhov no yuav txuag tau $ 5-15 ntawm tus kheej sticks. Nws txhawb kev ua haujlwm nrog ob hom Bluetooth 4.1: Classic thiab Tsawg Zog. Qhov no yuav tso cai rau koj ua haujlwm nrog txhua yam khoom siv, suav nrog lub mloog pob ntseg, nas, keyboards, thiab cov xov xwm hauv tsev.

Txhawm rau txuag nyiaj thiab ua kom muaj kev sib raug zoo nrog Wi-Fi platform, nws tau nthuav tawm raws li ib leeg-band module nrog kev txhawb nqa rau 802.11n tus qauv, muab cov ntaub ntawv xa mus txog 150 Mbps. Tsuas muaj ib lub kav hlau txais xov xwb, yog li kev nrawm dua tsis muaj rau cov neeg siv.

Cov txheej ntawm wired interfaces thiab lawv layout tsis tau hloov. Tag nrho tib ob khub ntawm USB 2.0, microUSB rau kev sib txuas hluav taws xob thiab khoom siv, HDMI thiab 3.5 hli jack rau tso tawm cov kwj digital lossis analog. Raws li cov chaw tsim khoom, kev ua haujlwm ntawm kev ua haujlwm nrog GPIO, CSI thiab DSI tsis tau hloov pauv, yog li rov nruab cov tsav tsheb tsis tas yuav tsum tau ua.

Operating systems thiab software

Raspberry Pi 3 tau txais kev txhawb nqa los ntawm cov txheej txheem kev ua haujlwm, suav nrog (tus nom Debian variant), nrog rau Debian Wheezy, Ubuntu MATE, Fedora Remix. Raspbian niaj hnub no muaj ntau cov ntawv thov rau kev kawm thiab kev ua haujlwm hauv Python (cov lus tseem ceeb rau kev ua haujlwm nrog Raspberry), ib qho dawb version ntawm Wolfram Mathematica.

Standard shells rau lub media center tau nthuav tawm thiab. Cov khoom siv faib khoom ntiag tug ua haujlwm ntawm lub rooj tsav xwm thib peb hauv tib txoj kev, ntawm PowerShell, nrog kev txhawb nqa rau 32-ntsis daim ntawv thov. Tag nrho cov kev khiav hauj lwm no tau ntev tau paub rau cov neeg nyiam, lawv tau hloov kho zoo kawg nkaus thiab tsis muaj kev txaus siab tshwj xeeb hauv lub moj khaum ntawm kev tshuaj xyuas.

Raspberry Pi 3 ua haujlwm nrog lwm lub tshuab thiab. Ua ntej, qhov no yog Android TV, uas peb tau sau txog tsis ntev los no. Nws ua hauj lwm tsuas yog nyob rau hauv lub thib peb version ntawm lub rooj tsavxwm, thiab tsis muaj downgrade yuav tsum tau. Nrog Android TV ntsia, koj tuaj yeem tau txais qhov pheej yig heev tab sis ruaj khov thiab lub zog siv hluav taws xob hauv tsev tshaj tawm.

Thib ob, Chromium OS faib. Peb tuaj yeem tham tsis kawg txog qhov muaj peev xwm ntawm Chromium. Qhov kev faib tawm no hloov kho sai sai raws li cov txheej txheem rau Chromebooks. Thiab, tej zaum, nws yog rau nws lub neej yav tom ntej ntawm Raspberry raws li lub tsev khoom siv - lub desktop lossis lub rooj zaum computer, server lossis lub hauv paus rau lub tsev ntse.

Hmoov tsis zoo, vim muaj ntau zaus, cov cua sov ntawm lub rooj tsavxwm tau nce ntau. Qee qhov kev ntsuam xyuas qhia tias tus processor tuaj yeem ncav cuag 101 ° C. Muaj tseeb tiag, cov neeg tsim khoom tau ua haujlwm zoo throttling (txo qhov ua haujlwm zaus thaum rhuab). Tab sis ntxiv cua txias, txawm tias passive, tseem xav tau.

Piv rau yav dhau los versions ntawm Raspberry, qhov kev ua tau zoo heev. Qhov no qhia li cas?

  • Lub RAM txaus rau kev ua haujlwm tas mus li nrog cov qauv siv rau lub rooj tsavxwm.
  • Ua haujlwm nrog graphical interface (GUI) ua tiav yam tsis muaj kev lag luam thiab ntaiv.
  • Ua haujlwm hauv chaw ua haujlwm NIX cov neeg kho tuaj yeem ua tau txawm tias muaj cov ntaub ntawv hnyav.
  • Quake III ntawm qhov chaw siab tshaj plaws muab txog 90 FPS.
  • Yog tsis muaj hardware decoding, YouTube yeeb yaj duab yog ua si ntawm 480p; yog hais tias kho vajtse decoding enabled, yeeb yaj duab mus txog 1080p yog ua si.

Kev sib piv nrog cov neeg sib tw

Nrog built-in wireless interfaces, kev yuav khoom ntawm Raspberry Pi 3 yuav muaj txiaj ntsig ntau dua li yav dhau los. Yav dhau los, koj yuav tsum yuav cais Bluetooth thiab Wi-Fi sticks uas ua haujlwm yam tsis muaj kev txhim kho cov tsav tsheb. Lawv muab kev nrawm zoo ib yam li cov chips sib xyaw, tab sis nce tus nqi ntawm kev tsim los ntawm tsawg kawg yog $ 5 rau txhua qhov module.

Qhov kev ua tau zoo dua piv rau feem ntau cov analogs, xws li Raspberry Pi 2, Txiv kab ntxwv Pi, Txiv tsawb Pi, tso cai rau koj siv Malinka thib peb raws li lub desktop tiag tiag, uas feem ntau lwm yam khoom siv tsis muaj peev xwm.

Yog li, Raspberry Pi 3 yog qhov pheej hmoo tshaj plaws platform rau xov tooj cua amateurs, kiv cua programmers, thiab txawm DIYers ntawm tus nqi ntawm 10. Ntawm nws koj tuaj yeem tsis tsuas yog tsim qee yam khoom siv yooj yim, tab sis kuj kawm txog kev pab cuam thiab ua haujlwm nrog microcontrollers.
