Raspberry Pi 4 Model B yog cov khoom siv tshiab tshaj plaws hauv cov khoos phis tawj nrov Raspberry Pi. Nws muaj kev nce hauv av hauv cov txheej txheem ceev, kev ua haujlwm multimedia, nco, thiab kev sib txuas piv rau cov tiam dhau los
Raspberry Pi 3 Model B +, thaum tuav rov qab sib raug zoo thiab zoo sib xws siv zog. Rau cov neeg siv kawg, Raspberry Pi 4 Model B muab cov duab ua tau zoo piv rau kev nkag-qib x86 PC systems.
Cov khoom lag luam tseem ceeb no suav nrog kev ua haujlwm siab 64-ntsis plaub-core processor-ntxhais, ob qho kev txhawb nqa ntawm kev daws teeb meem txog 4K txog ntawm ib khub micro-HDMI chaw nres nkoj, kho vajtse video txiav txim siab txog li 4Kp60, mus txog 8GB ntawm RAM, dual -band 2.4 / 5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, thiab PoE muaj peev xwm (ntawm cais PoE HAT ntxiv-ntawm).
Lub tshuab ua ke dual wireless wireless thiab Bluetooth muaj cov ntawv pov thawj ua raws cov qauv, tso cai rau cov txiag tsim los rau hauv cov khoom lag luam kawg nrog kev txo qis kev soj ntsuam kom ua raws, txhim kho cov nqi thiab sijhawm ua lag luam.

CEEB TOOM
Cov khoom no yuav tsum tsuas yog txuas nrog lub zog hluav taws xob sab nraud ntawm 5V / 3A DC lossis 5.1V / 3A DC yam tsawg kawg Ib qho khoom siv hluav taws xob sab nraud siv nrog Raspberry Pi 4 Model B yuav tsum ua raws li cov cai thiab cov qauv siv tau hauv lub tebchaws uas tau npaj tseg. siv.
- Cov khoom no yuav tsum ua haujlwm hauv qhov cua zoo thiab, yog siv sab hauv rooj plaub, rooj plaub yuav tsum tsis txhob npog.
- Cov khoom no yuav tsum muab tso rau ntawm qhov chaw ruaj, tiaj, tsis muaj qhov chaw zoo nyob rau hauv kev siv thiab yuav tsum tsis txhob tiv tauj los ntawm cov khoom lag luam.
- Cov kev sib txuas ntawm cov khoom siv tsis raug rau qhov sib txuas ntawm GPIO tej zaum yuav cuam tshuam rau kev ua raws cai thiab ua rau muaj kev puas tsuaj rau lub tsev thiab ua tsis tau raws lub warranty.
- Txhua tus yuam sij siv nrog cov khoom no yuav tsum ua raws li cov qauv tsim nyog rau lub teb chaws siv thiab cim kom raug raws li ntseeg tau tias kev nyab xeeb thiab ua tiav tau raws li qhov xav tau. Cov ntsiab lus no suav nrog tab sis tsis txwv rau cov twj paj nruag, tus saib xyuas thiab nas thaum siv nrog Raspberry Pi.
- Qhov chaw txuas txuas txuas nrog uas tsis suav cov xaim lossis txuas, lub cable lossis txuas txuas yuav tsum muaj cov rwb thaiv tsev txaus thiab kev ua haujlwm kom thiaj li ua tiav cov kev ua tau zoo thiab kev nyab xeeb ua tau.
SAFETY CEEB TOOM
Txhawm rau kom tsis txhob ua haujlwm tsis zoo lossis puas tsuaj rau cov khoom no thov saib raws li hauv qab no:
- Tsis txhob nthuav dav rau dej, noo noo lossis qhov chaw ntawm qhov chaw conductive nto thaum ua haujlwm.
- Tsis txhob nthuav tawm nws kom kub los ntawm txhua qhov; Raspberry Pi 4 Qauv B yog tsim rau kev ua haujlwm txhim khu kev qha ntawm chav ib puag ncig ib puag ncig.
