I-Raspberry Pi 4 Model B 
Kuphelileview
I-Raspberry Pi 4 Model B ingumkhiqizo wakamuva kuhlu oludumile lwe-Raspberry Pi lwamakhompyutha. Inikeza ukwanda kokwephuka komhlaba ngejubane leprosesa, ukusebenza kwe-multimedia, inkumbulo nokuxhuma kuqhathaniswa ne-Raspberry Pi 3 Model B + yesizukulwane sangaphambilini, ngenkathi kugcinwa ukuhambisana okubuyela emuva nokusetshenziswa kwamandla okufanayo. Kumsebenzisi wokugcina, i-Raspberry Pi 4 Model B inikeza ukusebenza kwedeskithophu okuqhathaniswa nezinhlelo zokungena ezingeni le-x86 PC.
Izici ezibalulekile zalo mkhiqizo zifaka phakathi iprosesa esebenza kakhulu ye-64-bit quad-core processor, ukwesekwa okubonisa okumbili kuzinqumo kuze kufike ku-4K ngezibuko le-micro-HDMI, i-hardware video decode efinyelela ku-4Kp60, kuze kufike ku-8GB ye-RAM, kabili -band 2.4 / 5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (nge-add-on ehlukile ye-PoE HAT).
I-LAN engenantambo engenantambo ne-Bluetooth kunesitifiketi sokuhambisana, okuvumela ibhodi ukuthi lenzelwe imikhiqizo ekugcineni ngokuhlolwa kokuncishiswa okunciphise kakhulu, kuthuthukisa izindleko nesikhathi sokumaketha.

I-5V DC ngeheda ye-GPIO (ubuncane be-3A1)
Amandla ngaphezu kwe-Ethernet (PoE) “anikwe amandla (adinga i-PoE HAT ehlukile)
Imvelo:
Ukushisa okusebenzayo 0-50ºC
Ukuthobela:
Ukuthola uhlu olugcwele lokuvunyelwa komkhiqizo wendawo nowesifunda, sicela uvakashele https://www.raspberrypi.org/documentation/hardware/raspberrypi/conformity.md
Isikhathi sokukhiqiza:
I-Raspberry Pi 4 Model B izohlala ikhiqizwa kuze kube okungenani ngoJanuwari 2026.
Imininingwane Engokwenyama
IZIXWAYISO
- Lo mkhiqizo kufanele uxhumeke kuphela kunikezelo lwangaphandle lwamandla olukalwe ku-5V / 3A DC noma ku-5.1V / 3A DC ubuncane1. Noma yikuphi ukunikezwa kwamandla kwangaphandle okusetshenziswe ne-Raspberry Pi 4 Model B kuzothobela imithethonqubo efanele kanye namazinga asebenzayo ezweni lokusetshenziswa okuhlosiwe.
- Lo mkhiqizo kufanele usebenze endaweni enomoya omuhle futhi, uma usetshenziswa ngaphakathi kwecala, icala akufanele limbozwe.
- Lo mkhiqizo kufanele ubekwe endaweni ezinzile, eyisicaba, engaqhubi lapho kusetshenziswa futhi akufanele kuthintwe izinto ezihamba kahle.
- Ukuxhumeka kwamadivayisi angahambelani noxhumano lwe-GPIO kungathinta ukuhambisana futhi kuholele ekulimaleni kweyunithi futhi kungasebenzi iwaranti.
- Yonke imingcele esetshenzisiwe ngalo mkhiqizo kufanele ihambisane nezindinganiso ezifanele zezwe elisetshenziswayo futhi imakwe ngokufanele ukuqinisekisa ukuthi izidingo zokuphepha nokusebenza ziyahlangabezana. Lezi zihloko zifaka kepha azikhawulelwanga kumakhibhodi, ama-monitors namagundane lapho zisetshenziswa ngokuhlanganyela ne-Raspberry Pi.
- Lapho okuxhunywe khona imingcele engafaki ikhebula noma isixhumi, ikhebula noma isixhumi kufanele sinikeze ukwahlukanisa nokusebenza okwanele ukuze kuhlangatshezwane nezidingo ezifanele zokusebenza nezokuphepha.
IZIYALELO ZOKUPHEPHA
Ukugwema ukungasebenzi kahle noma ukulimala kwalo mkhiqizo sicela uqaphele okulandelayo:
- Ungadaluli amanzi, umswakama noma indawo endaweni eguqukayo ngenkathi isebenza.
- Ungayivezi ekushiseni kunoma yimuphi umthombo; I-Raspberry Pi 4 Model B yenzelwe ukusebenza okuthembekile emazingeni okushisa ajwayelekile egumbi.
- Qaphela ngenkathi uphatha ukugwema ukulimala komshini noma kagesi ebhodini lesifunda eliphrintiwe nezixhumi.
- Gwema ukuphatha ibhodi lesifunda eliphrintiwe ngenkathi linikwa amandla futhi liphatha kuphela emaphethelweni ukunciphisa ubungozi bokulimala kokukhishwa kwe-electrostatic.
Kungahle kusetshenziswe isisetshenziswa esihle segesi esingu-2.5A uma ama-peripherals e-USB asezansi angaphansi kwe-500mA isiyonke.
