Raspberry Pi 4 Umzekelo B

Ngaphezuluview

IRaspberry Pi 4 Model B yimveliso yamva nje kuluhlu oludumileyo lweRaspberry Pi lweekhompyuter. Ibonelela ngokunyuka komhlaba kwisantya somprosesa, ukusebenza kwemultimedia, imemori, kunye noqhagamshelo xa kuthelekiswa nesizukulwana sangaphambili iRaspberry Pi 3 Model B +, ngelixa igcina ukuhambelana ngasemva kunye nokusetyenziswa kwamandla afanayo. Kumsebenzisi wokugqibela, iRaspberry Pi 4 iModeli B ibonelela ngentsebenzo yedesktop enokuthelekiswa nenqanaba lokungena x86 iinkqubo zePC.

Iimpawu eziphambili zale mveliso ziquka ukusebenza okuphezulu kwe-64-bit quad-core processor, inkxaso ye-display-display kwizisombululo ukuya kwi-4K ngokusebenzisa i-micro-HDMI port, i-hardware decode decode ukuya kwi-4Kp60, ukuya kwi-8GB ye-RAM, kabini. -band 2.4 / 5.0 GHz i-wireless LAN, i-Bluetooth 5.0, i-Gigabit Ethernet, i-USB 3.0, kunye nekhono le-PoE (nge-add-on ye-PoE HAT eyahlukileyo).

I-LAN ye-wireless ezimbini kunye neBluetooth zinesatifikethi sokuthotyelwa kwemodyuli, evumela ibhodi ukuba iyilwe kwiimveliso zokugqibela kunye novavanyo oluthotyelwe kakhulu lokuthotyelwa, ukuphucula zombini iindleko kunye nexesha lokuthengisa.

IZILUMKISO

Le mveliso kufuneka iqhagamshelwe kuphela kunikezelo lwamandla lwangaphandle olubekwe kwi-5V/3A DC okanye 5.1V/3A DC ubuncinci1. Naluphi na unikezelo lwamandla lwangaphandle olusetyenziswe kunye neRaspberry Pi 4 Model B iya kuhambelana nemimiselo efanelekileyo kunye nemigangatho esebenzayo kwilizwe ekujoliswe kulo.
Le mveliso kufuneka iqhutywe kwindawo enomoya kwaye, ukuba isetyenziswe ngaphakathi kwimeko, ityala akufanele lifakwe.

Le mveliso kufuneka ibekwe kwindawo ezinzileyo, eyisicaba, engaqhubekiyo esetyenziswayo kwaye akufanele idibane nezinto eziqhubayo.
Ukudityaniswa kwezixhobo ezingahambelaniyo kuqhagamshelo lwe-GPIO kunokuchaphazela ukuthotyelwa kwaye kubangele umonakalo kwiyunithi kwaye ingasebenzi iwaranti.

Zonke iiperipherals ezisetyenziswa kule mveliso kufuneka zihambelane nemigangatho efanelekileyo yelizwe elisetyenziswayo kwaye zimakishwe ngokufanelekileyo ukuqinisekisa ukuba iimfuno zokhuseleko kunye nokusebenza ziyafezekiswa. La manqaku abandakanya kodwa akaphelelanga kwiikhibhodi, iimonitha kunye neempuku xa zisetyenziswa ngokubambisana neRaspberry Pi.
Apho iiperipherals ziqhagamshelwe ezingabandakanyi intambo okanye isiqhagamshelo, intambo okanye isiqhagamshelo kufuneka sinikezele ngokugquma okwaneleyo kunye nokusebenza ukuze kuhlangatyezwane neemfuno zokusebenza ezifanelekileyo kunye nokhuseleko.

IMIYALELO YOKHUSELEKO

Ukuthintela ukungasebenzi kakuhle okanye ukonakala kule mveliso nceda uqaphele oku kulandelayo:

Musa ukubeka esichengeni samanzi, ukufuma okanye indawo kumphezulu oqhubayo ngelixa usebenza.

Musa ukuwubeka kubushushu nakuwuphi na umthombo; IRaspberry Pi 4 iModeli B yenzelwe ukusebenza okuthembekileyo kumaqondo obushushu aqhelekileyo egumbi.
Qaphela ngelixa uphatha ukuphepha umonakalo owenziwe ngoomatshini okanye wombane kwibhodi yesekethe eprintiweyo kunye nezihlanganisi.

Kuphephe ukuphatha ibhodi yesekethe eprintiweyo ngelixa iqhutywa kwaye iphathwa kuphela ngasemiphethweni ukunciphisa umngcipheko womonakalo wokukhupha i-electrostatic.

Umgangatho olungileyo wombane we-2.5A unokusetyenziselwa ukuba izixhobo ezisezantsi ze-USB zisebenzisa ngaphantsi kwe-500mA iyonke.
