Puas yog Raspberry Pi 3 Cov Khoom Siv Tseem Ua Haujlwm?
Yog lawm, cov khoom siv Raspberry Pi 3 tseem ua haujlwm tau zoo nyob rau xyoo 2025. Cov khoom siv no suav nrog txhua yam uas xav tau rau feem ntau cov haujlwm nyiam, nrog rau kev lees paub kho vajtse ntau lawm los ntawm 2028-2030 thiab ua tiav software txhawb nqa los ntawm qhov tseeb Raspberry Pi OS. Kev ua tau zoo khiav 2-3 zaug qeeb dua li cov qauv tshiab rau kev xav tau kev ua haujlwm, tab sis cov khoom siv ua haujlwm tau zoo.
Dab tsi suav nrog hauv Raspberry Pi 3 Cov Khoom Siv
Lub Raspberry Pi Foundation tau cog lus los txuas ntxiv cov sijhawm tsim khoom rau txhua qhov Pi 3 variants. Tus Qauv B tseem nyob hauv kev tsim khoom kom txog rau thaum Lub Ib Hlis 2028, thaum Model B + txuas ntxiv mus rau Lub Ib Hlis 2030. Qhov no txhais tau tias kev yuav Raspberry Pi 3 cov khoom siv niaj hnub no tau lees tias muaj cov khoom muaj thiab hloov pauv yam tsawg kawg peb xyoos ntxiv.
Cov neeg muag khoom raug cai xws li CanaKit, Vilros, thiab Adafruit tseem tsim cov khoom siv Raspberry Pi 3 tiav nrog cov khoom pov thawj. Cov khoom siv no feem ntau suav nrog lub rooj tsavxwm, lub hwj chim, rooj plaub, microSD daim npav, thiab cov khoom siv yooj yim. Tus qauv 40-pin GPIO header ua kom muaj kev sib raug zoo nrog ntau txhiab tus HATs uas twb muaj lawm thiab nthuav tawm cov rooj sib tham tau tsim txij li xyoo 2016.
Cov kev xav tau ntawm lub zog tseem ncaj nraim nrog Pi 3B xav tau 5V / 2.5A ntawm microUSB, thaum B + variant xav tau 5V / 2.5A nrog kev txhim kho lub zog. Ob qho kev qhia tshwj xeeb ua haujlwm nrog cov khoom siv hluav taws xob uas muaj USB feem ntau, txawm hais tias Raspberry Pi fais fab mov tshem tawm cov teeb meem feem ntau cuam tshuam txog kev tsis muaj hluav taws xob.
Software Compatibility hauv 2025
Raspberry Pi OS (yav tas los Raspbian) muab kev txhawb nqa tag nrho rau Pi 3 kho vajtse hauv nws lub Tsib Hlis 2025 tso tawm, raws li Debian 13 "Trixie." Lub operating system tau txais kev ruaj ntseg hloov tshiab tsis tu ncua thiab tswj kev sib raug zoo nrog txhua pob software tam sim no muaj los ntawm APT repositories.
Ob leeg 32-ntsis thiab 64-ntsis versions khiav ntawm Pi 3 kho vajtse. Lub 64-ntsis OS xa cov kev ua tau zoo tshaj plaws ntawm Pi 3B + piv rau 32-ntsis, txawm hais tias cov neeg siv qhia txog 32-ntsis version xav tias teb ntau dua ntawm tus qauv Pi 3B. Lub OS suav nrog cov browsers niaj hnub (Chromium thiab Firefox), cov cuab yeej txhim kho (Thonny, Geany), thiab cov ntawv thov tseem ceeb tawm ntawm lub thawv.
Legacy software compatibility txuas mus rau cov laus operating systems thaum xav tau. Cov neeg siv tau ua tiav kev xa tawm los ntawm 2020-2023 rau cov haujlwm tshwj xeeb uas xav tau cov pob ntawv qub, txawm hais tias txoj hauv kev no ua rau muaj kev ruaj ntseg hloov tshiab. Qhov yooj yim xaiv ntawm kev txiav-ntug thiab ruaj khov software ua rau Pi 3 siv tau rau cov ntawv sau nrog kev xa mus ntev.
Thib peb-txoj haujlwm ua haujlwm xws li LibreELEC, OSMC, RetroPie, thiab Tus Pabcuam Hauv Tsev tuav Pi 3 txhawb nqa. Cov kev faib tshwj xeeb no ua kom zoo rau cov kev siv tshwj xeeb thiab feem ntau ua tau zoo dua li khiav software sib npaug ntawm Raspberry Pi OS.

Cov Haujlwm Uas Xav Tau Cov Khoom Tshiab Tshiab
Kev hloov pauv hauv desktop tshaj li Pi 3 lub peev xwm rau kev siv tsis tu ncua. Cov ntawv thov web niaj hnub no, software tsim khoom, thiab kev ua haujlwm ntau xav tau ntau RAM thiab ua lub zog. Cov neeg siv xav tau kev ua haujlwm niaj hnub desktop yuav tsum xaiv Pi 4 lossis Pi 5 hloov.
AI thiab tshuab kev kawm tej yaam num xav tau ntau yam kev pab cuam xam. Thaum quantized LLMs tau technically khiav ntawm Pi 3 siv llama.cpp, lub sij hawm teb ua pov thawj impractically qeeb. Kev pom kev siv computer siv TensorFlow lossis PyTorch ua haujlwm tsis zoo piv rau cov qauv tshiab nrog CPU thiab RAM specifications zoo dua.
4K video playback thiab cov kev pabcuam streaming niaj hnub xav tau Pi 4 lossis tshiab dua. Pi 3's GPU thiab codec kev txhawb nqa tsis ua raws li cov cai tam sim no DRM rau cov kev pabcuam xws li Netflix, Disney+, lossis Amazon Prime Video. Txawm tias nrog kev ua haujlwm, kev ua haujlwm tseem tsis txaus siab.
Network- txuas nrog kev tuav tuav ib txhij ntau- cov neeg siv tau txais txiaj ntsig los ntawm USB 3.0 ceev thiab Gigabit Ethernet muaj peev xwm pom hauv cov qauv tom qab. Kev hloov ntaub ntawv loj thiab RAID arrays dhau Pi 3 cov kev txwv kev sib txuas.
Advanced robotics tej yaam num yuav tsum tau tiag tiag - lub sij hawm sensor ua thiab lub cev muaj zog tswj lub ntsej muag lub sij hawm txwv nrog Pi 3 tus tib - xov kev ua tau zoo. Lub latency cuam tshuam cov kev txav mus los thiab cov khoom siv tshawb pom qhov twg cov qauv tshiab muaj qhov ua tau zoo dua.
Raspberry Pi 3 Cov Khoom Siv Nqis vs Cov Qauv Tshiab
Ua kom tiav Pi 3 cov khoom pib pib muag ntawm $ 70- $ 90, nyob ntawm cov khoom siv. Piv nrog Pi 4 (4GB) cov khoom siv raug nqi $ 100- $ 120, thaum Pi 5 (4GB) cov khoom siv txij li $ 120- $ 150. Qhov $ 30- $ 60 tus nqi sib txawv nruab nrab yog 40-75% ntawm Pi 3 cov khoom siv.
Rau cov haujlwm hauv Pi 3 qhov muaj peev xwm ntau, xaiv cov khoom siv Raspberry Pi 3 ua pov thawj tus nqi ntau dua - zoo. Kev teeb tsa hauv tsev automation, Pi-lub qhov server, lossis retro gaming system tsis muaj dab tsi los ntawm kev ua haujlwm ntxiv, ua rau kev txuag nyiaj ntau heev. Kev siv hluav taws xob qis dua kuj txo cov nqi hluav taws xob ntev - lub sij hawm hluav taws xob ib txwm muaj - ntawm cov haujlwm.
Siv Pi 3 boards thiab cov khoom siv tshwm sim ntau zaus ntawm ob- tes kev lag luam ntawm $ 30- $ 50, muab ntau dua tus nqi rau cov ntawv thov tsim nyog. Lub platform paub tab txhais tau tias kev txheeb xyuas cov khoom siv ua haujlwm ncaj qha, thiab cov qauv tsim muaj zog ua rau kho vajtse tsis ua haujlwm tsis tshua muaj.
Txawm li cas los xij, kev yuav Pi 3 rau tej yaam num uas yuav kawg outgrow nws lub peev xwm nkoos thawj zaug peev. Cov neeg siv npaj yuav nthuav dav kev ua haujlwm lossis khiav cov ntawv thov xav tau ntau dua tom qab yuav tsum tau nqis peev hauv cov khoom siv tshiab tam sim ntawd tsis yog hloov kho dua li ob peb lub hlis.
Cov lus nug nquag
