Raspberry Pi 4 Model B bụ ngwaahịa kachasị ọhụrụ na kọmpụta Raspberry Pi ama ama. Ọ na-enye mmụba na-agbaji ala na ọsọ nhazi, arụmọrụ multimedia, ebe nchekwa, na njikọta tụnyere ọgbọ mbụ Raspberry Pi 3 Model B+, ebe ọ na-ejigide ndakọrịta azụ na oriri ike yiri ya. Maka onye ọrụ njedebe, Raspberry Pi 4 Model B na-enye arụmọrụ desktọpụ tụnyere sistemu PC x86 ọkwa ntinye.

Akụkụ bụ isi nke ngwaahịa a gụnyere 64-bit quad-core processor na-arụ ọrụ dị elu, nkwado ngosipụta abụọ na mkpebi ruo 4K site na ọdụ ụgbọ mmiri micro-HDMI, ngbanwe vidiyo ngwaike ruo 4Kp60, ruo 8GB nke RAM, dual -band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, na ike PoE (site na mgbakwunye PoE HAT dị iche).

Igwe ikuku LAN na Bluetooth nwere asambodo nnabata modular, na-enye ohere ka emebe bọọdụ ka ọ bụrụ ngwaahịa ngwụcha yana nnwale nnabata belata nke ukwuu, na-emezi ma ọnụ ahịa yana oge ịzụ ahịa.

Raspberry Pi 4 Model B ga-anọgide na mmepụta ruo opekata mpe Jenụwarị 2026.

Nkọwapụta anụ ahụ

Ịdọ aka ná ntị

Ekwesịrị ijikọ ngwaahịa a na ọkọnọ ike mpụga nke 5V/3A DC ma ọ bụ 5.1V/3A DC kacha nta1. Ọkụ ọkụ mpụga ọ bụla ejiri ya na Raspberry Pi 4 Model B ga-agbaso ụkpụrụ na ụkpụrụ dị mkpa dị na obodo e bu n'obi iji.
Ekwesịrị iji ngwaahịa a rụọ ọrụ na ebe ikuku na-ekpo ọkụ ma, ọ bụrụ na ejiri ya n'ime ikpe, ekwesighi ikpuchi ikpe ahụ.

Ekwesịrị idowe ngwaahịa a n'elu ebe kwụsiri ike, dị larịị, ebe anaghị arụ ọrụ nke a na-eji eme ihe na ihe ndị na-eduzi agaghị akpọtụrụ ya.
Njikọ nke ngwaọrụ na-adabaghị na njikọ GPIO nwere ike imetụta nrubeisi wee bute mmebi na unit ahụ ma mebie akwụkwọ ikike ahụ.

Akụkụ niile ejiri ngwaahịa a ga-agbaso ụkpụrụ ndị dị mkpa maka obodo ojiji yana akara ya ka ọ hụ na emezuru ihe achọrọ nchekwa na arụmọrụ. Edemede ndị a gụnyere mana ọnweghị oke na ahụigodo, ihe nleba anya na ụmụ oke mgbe ejiri ya na Raspberry Pi.
Ebe ejikọrọ mpụta nke na-agụnyeghị eriri ma ọ bụ njikọ, eriri ma ọ bụ njikọ ga-enye mkpuchi na arụ ọrụ zuru oke ka e wee mezuo ihe ndị dị mkpa na nchekwa chọrọ.

Ntuziaka nchekwa

Iji zere mmebi ma ọ bụ mebie ngwaahịa a, biko hụ ihe ndị a:

Ekpughela na mmiri, mmiri ma ọ bụ tinye n'elu ihe na-eduzi mgbe ị na-arụ ọrụ.

Ekpughela ya na okpomọkụ sitere na isi iyi ọ bụla; A haziri Raspberry Pi 4 Model B maka ịrụ ọrụ a pụrụ ịdabere na ya na okpomọkụ nke ime ụlọ.
Kpachapụ anya ka ị na-ejizi ka ịzenarị mmebi nke igwe ma ọ bụ eletrik na bọọdụ sekit na njikọ njikọ.
