IRaspberry Pi 4 Model B yimveliso yamva nje kuluhlu oludumileyo lweRaspberry Pi lweekhompyuter. Inika ukonyuka okuqhekeka komhlaba kwisantya seprosesa, ukusebenza kwemultimedia, inkumbulo, kunye nonxibelelwano xa kuthelekiswa nesizukulwana sangaphambili.
I-Raspberry Pi 3 Model B +, ngelixa igcina ukuhambelana ngasemva kunye nokusetyenziswa kwamandla afanayo. Kumsebenzisi wokugqibela, iRaspberry Pi 4 iModeli B ibonelela ngokusebenza kwedesktop ngokuthelekiswa 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 ubuncinci Naluphi na unikezelo lwamandla lwangaphandle olusetyenziswa kunye neRaspberry Pi 4 Model B luya kuthobela imimiselo efanelekileyo kunye nemigangatho esebenzayo kwilizwe ekujoliswe kulo. sebenzisa.
- 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 ngeli lixa inikwe amandla kwaye iphathwa kuphela ngeencam zokunciphisa umngcipheko womonakalo wokukhupha i-electrostatic.
Umgangatho olungileyo wombane we-2.5A unokusetyenziselwa ukuba izixhobo ezisezantsi ze-USB zisebenzisa ngaphantsi kwe-500mA iyonke.
