Raspberry Pi 4B: Ib qho me me thiab muaj zog microcomputer

Lus piav qhia luv luv:

cov khoom piav qhia
Nws yog microcomputer motherboard raws li ARM, siv SD / MicroSD daim npav ua lub cim xeeb hard disk. Muaj 1/2/4 USB interfaces thiab 10/100 Ethernet interface nyob ib ncig ntawm daim npav motherboard (hom A tsis muaj qhov chaw nres nkoj network), uas tuaj yeem txuas nrog Keyboard, nas thiab network cable, nrog rau TV tso zis interface rau video analog signals thiab HDMI high-txhais video tso zis interface. Cov ntsiab lus saum toj no yog tag nrho kev koom ua ke ntawm lub motherboard uas tsuas yog me ntsis loj dua li daim npav rho nyiaj. Nws muaj tag nrho cov haujlwm yooj yim ntawm lub PC thiab tsuas yog xav tau txuas nrog lub TV. thiab cov keyboard, koj tuaj yeem ua tau ntau yam haujlwm xws li cov ntawv nthuav qhia, sau lo lus, ua si ua si, ua si cov yeeb yaj kiab siab, thiab ntau dua. Raspberry Pi B qauv tsuas yog muab lub computer board, tsis muaj lub cim xeeb lub zog, keyboard, chassis lossis kev sib txuas.

Cov yam ntxwv tseem ceeb ntawm Raspberry Pi 4B:
Kev ua haujlwm ceev dua:
1. Qhov tseeb Broadcom 2711 quad-core Cortex A72 (ARM V8-A) 64-ntsis SoC processor clocked ntawm 1.5GHz txhim kho lub zog noj; thiab thermals ntawm Pi 4 + B txhais tau hais tias CPU ntawm BCM2837 SoC tam sim no tuaj yeem khiav ntawm 1.5 GHz Qhov ntawd yog 20% kev txhim kho dua tus qauv Pi 3 yav dhau los, uas tau khiav ntawm 1.2GHz.
2. Kev ua yeeb yaj kiab ntawm Pi 4 B tau raug kho dua tshiab nrog kev saib xyuas dual ntawm kev daws teeb meem txog 4K ntawm ob lub chaw nres nkoj; kho vajtse video txiav txim siab txog 4Kp60, kev txhawb nqa rau H 265 kev txiav txim siab (4kp 60); H.264 thiab MPEG-4 decoding (1080p60 ).

Faster wireless:
1. Muab piv rau tus qauv Pi 3 yav dhau los, qhov kev hloov pauv tseem ceeb hauv Pi 4 B yog qhov suav nrog qhov tshiab, nrawm dua; dual-band wireless nti uas txhawb 802.11 b/g/n/ac wireless LAN.
2. Dual-band 2.4GHz thiab 5GHz wireless LAN txhawb nqa kev sib txuas sai dua nrog kev cuam tshuam tsawg dua, thiab PCB kav hlau txais xov tshiab thev naus laus zis txhawb kev txais tos zoo dua.
3. Qhov tseeb 5.0 tso cai rau koj siv lub wireless keyboard / trackpad nrog ntau ntau dua ua ntej, tsis muaj dongles ntxiv; khaws cov khoom kom huv si.

Enhanced Ethernet txuas:
1. Pi 4 B muaj kev sib txuas ceev ceev, nrog USB 3.0 thev naus laus zis; ua tsaug rau qhov kho dua tshiab USB / LAN nti; koj yuav tsum pom nrawm txog 10 npaug sai dua li cov qauv Pi yav dhau los.
2. Lub GPIO header tseem zoo li qub, 40 tus pins; tag nrho rov qab sib xws nrog cov niam ntawv yav dhau los, xws li thawj peb tus qauv ntawm Pi. Txawm li cas los xij; Nws yuav tsum raug sau tseg tias cov ntsaws ruaj ruaj PoE tshiab tuaj yeem cuam tshuam nrog cov khoom hauv qab ntawm qee lub kaus mom; xws li cov kaus mom zaj sawv.
