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 ma e jiri ya tụnyere ọgbọ gara aga
Raspberry Pi 3 Model B+, ka ọ na-ejigide ndakọrịta azụ yana oriri ike yiri ya. Maka onye ọrụ njedebe, Raspberry Pi 4 Model B na-enye arụmọrụ desktọpụ tụnyere sistemụ x86 PC ntinye ọkwa.
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.
