I-Raspberry Pi 4 Model B ingumkhiqizo wakamuva ohlwini lwamakhompyutha oludumile lwe-Raspberry Pi. Inikeza ukukhuphuka okudabukisayo kwejubane lephrosesa, ukusebenza kwe-multimedia, inkumbulo, nokuxhumana uma kuqhathaniswa nesizukulwane sangaphambilini.
I-Raspberry Pi 3 Model B+, kuyilapho igcina ukuhambisana okuya emuva kanye nokusetshenziswa kwamandla okufanayo. Kumsebenzisi wokugcina, i-Raspberry Pi 4 Model B inikeza ukusebenza kwedeskithophu okuqhathaniswa nezinhlelo ze-PC zezinga lokungena ze-x86.
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.
Ukucaciswa

| I-GPIO: | Unhlokweni ojwayelekile we-40-pin GPIO (ubuyela emuva emuva ngokugcwele-uyahambisana namabhodi angaphambilini) |
| Ividiyo Nomsindo: | 2 × izimbobo ze-HDMI ezincane (kufika ku-4Kp60 asekelwe) Imbobo yokubonisa engu-2 ye-MIPI DSI Imbobo yekhamera engu-2 ye-MIPI CSI Umsindo we-4-pole stereo audio and composite video port |
| Imidiya exubile: | H.265 (4Kp60 khipha ikhodi); H.264 (1080p60 khipha ikhodi, 1080p30 encode); I-OpenGL ES, ihluzo ze-3.0 |
| Ukusekelwa kwekhadi le-SD: | I-Micro SD card slot yokulayisha uhlelo lokusebenza nokugcinwa kwedatha |
| Amandla okokufaka: | I-5V DC ngesixhumi se-USB-C (ubuncane be-3A 1 ) 5V DC nge-GPIO unhlokweni (ubuncane be-3A1) Amandla phezu kwe-Ethernet (PoE)–inikwe amandla (idinga i-PoE HAT ehlukene) |
| Imvelo: | Izinga lokushisa lokusebenza 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 kumandla angaphandle alinganiselwe ku-5V/3A DC noma 5.1V/3A DC ubuncane Noma ikuphi ukuphakelwa kwamandla kwangaphandle okusetshenziswa ne-Raspberry Pi 4 Model B kuzohambisana nemithethonqubo efanele futhi amazinga ayasebenza ezweni okuhloswe ngalo. sebenzisa.
- 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 lesekethe eliphrintiwe ngenkathi linikwe amandla futhi libamba kuphela emaphethelweni ukuze unciphise ubungozi bokulimala kokukhishwa kwe-electrostatic.
Kungahle kusetshenziswe isisetshenziswa esihle segesi esingu-2.5A uma ama-peripherals e-USB asezansi angaphansi kwe-500mA isiyonke.
