Raspberry Pi 4B

Inkcazelo emfutshane:

I-Raspberry Pi 4B yongezwa entsha kwi-Raspberry PI yosapho lweekhompyuter. Isantya seprosesa siphuculwe kakhulu xa kuthelekiswa nesizukulwana sangaphambili iRaspberry Pi 3B +. Inemultimedia etyebileyo, inkumbulo eninzi kunye noqhagamshelo olungcono. Kubasebenzisi bokugqibela, iRaspberry Pi 4B ibonelela ngokusebenza kwedesktop ngokuthelekiswa neenkqubo zokungena kwinqanaba le-x86PC.

I-Raspberry Pi 4B ine-64-bit ye-quad-core processor eqhuba kwi-1.5Ghz; Ukubonisa kabini ngesisombululo se-4K ukuya kuthi ga kwi-60fps ukuhlaziya; Ifumaneka kwiinketho ezintathu zememori: 2GB/4GB/8GB; Kwibhodi ye-2.4 / 5.0 Ghz i-WiFi engenazintambo ezimbini kunye ne-5.0 BLE amandla aphantsi eBluetooth; I-1 gigabit Ethernet port; 2 USB3.0 izibuko; 2 USB 2.0 izibuko; 1 5V3A izibuko lamandla.

I-Raspberry Pi 4 Model B (i-Raspberry Pi 4 i-Model B) isizukulwana sesine se-Raspberry PI yentsapho, i-microcomputer esebenza kakuhle, enexabiso eliphantsi. Iza ne-1.5GHz 64-bit quad-core ARM Cortex-A72 CPU (i-Broadcom BCM2711 chip) eyongeza kakhulu amandla okusebenza kunye nokusebenza kwemisebenzi emininzi. I-Raspberry PI 4B ixhasa ukuya kuthi ga kwi-8GB ye-LPDDR4 RAM, ine-USB 3.0 port yokudlulisa idatha ngokukhawuleza kwaye, ngokokuqala ngqa, yazisa i-USB Type-C interface yamandla yokutshaja ngokukhawuleza kunye namandla.

Imodeli ikwabonisa i-Micro HDMI interfaces ezimbini ezinokuthi ngaxeshanye zikhuphe ividiyo ye-4K yesisombululo kwiimonitha ezimbini, iyenze ilungele indawo yokusebenza esebenzayo okanye amaziko emultimedia. Uqhagamshelo oludityanisiweyo olungenazingcingo lubandakanya i-2.4/5GHz dual-band Wi-Fi kunye neBluetooth 5.0/BLE, iqinisekisa uthungelwano oluguquguqukayo kunye noqhagamshelwano lwesixhobo. Ukongeza, i-Raspberry PI 4B igcina i-GPIO pin, ivumela abasebenzisi ukuba badibanise iintlobo ezahlukeneyo ze-sensor kunye ne-actuators zophuhliso olwandisiweyo, okwenza kube yinto efanelekileyo yokufunda inkqubo, iiprojekthi ze-iot, iirobhothi kunye neentlobo ezahlukeneyo zokudala izicelo ze-DIY.
