Ọ bụ microcomputer motherboard dabere na ARM, na-eji kaadị SD/MicroSD dị ka diski ike ebe nchekwa. E nwere 1/2/4 USB interfaces na 10/100 Ethernet interface gburugburu kaadị motherboard (ụdị A enweghị a netwọk ọdụ ụgbọ mmiri), nke nwere ike jikọọ Keyboard, òké na netwọk USB, yana a TV mmepụta interface maka. akara ngosi analọgụ vidiyo na interface mmepụta vidiyo dị elu HDMI. Ngwa ndị a dị n'elu na-ejikọta ya na motherboard nke dị ntakịrị karịa kaadị kredit. Ọ nwere ọrụ niile bụ isi nke PC ma ọ dị mkpa ijikọ na TV. na ahụigodo, ị nwere ike ịrụ ọtụtụ ọrụ dị ka mpempe akwụkwọ, nhazi okwu, igwu egwuregwu, ịkpọ vidiyo nwere nkọwa dị elu, na ndị ọzọ. Ụdị Raspberry Pi B na-enye naanị bọọdụ kọmputa, enweghị ike nchekwa, ahụigodo, chassis ma ọ bụ njikọ.

Akụkụ bụ isi nke Raspberry Pi 4B:
Ọsọ nhazi ngwa ngwa:
1. Ihe ọhụrụ Broadcom 2711 quad-core Cortex A72 (ARM V8-A) 64-bit SoC processor na-emechi na 1.5GHz na-eme ka ike oriri dịkwuo mma; na thermal na Pi 4+B pụtara na CPU na BCM2837 SoC nwere ike na-agba ọsọ na 1.5 GHz Nke ahụ bụ nkwalite 20% karịa ụdị Pi 3 gara aga, nke na-agba na 1.2GHz.
2. A kwalitere arụmọrụ vidiyo na Pi 4 B site na nkwado nyocha abụọ na mkpebi ruo 4K site na ọdụ ụgbọ mmiri abụọ; Ndozi vidiyo ngwaike ruo 4Kp60, nkwado maka ngbanwe H 265 (4kp 60); H.264 na MPEG-4 ngbanwe (1080p60).

Ikuku ngwa ngwa:
1. Tụnyere ụdị Pi 3 gara aga, mgbanwe dị ịrịba ama na Pi 4 B bụ ntinye nke ọhụrụ, ngwa ngwa; mgbawa ikuku dual-band na-akwado 802.11 b/g/n/ac wireless LAN.
2. Dual-band 2.4GHz na 5GHz wireless LAN na-akwado njikọ netwọk ngwa ngwa na obere nnyonye anya, yana teknụzụ antenna PCB ọhụrụ na-akwado nnabata ka mma.
3. 5.0 kacha ọhụrụ na-enye gị ohere iji keyboard / trackpad ikuku nwere oke karịa ka ọ dị na mbụ, na-enweghị extra dongles; na-eme ka ihe dị ọcha.

Njikọ Ethernet emelitere:
1. Pi 4 B nwere ịkparịta ụka n'igwe ngwa ngwa ngwa ngwa, yana teknụzụ USB 3.0; ekele maka mgbawa USB/LAN kwalitere; ị ga-ahụ ọsọ ọsọ ruo ugboro 10 ngwa ngwa karịa ụdị Pi gara aga.
2. Ihe nkụnye eji isi mee GPIO ka dị otu, 40 atụdo; dakọtara kpamkpam na motherboards gara aga, dị ka ụdị atọ mbụ nke Pi. Otú ọ dị; ekwesiri iburu n'uche na plọg PoE ọhụrụ nwere ike ịbanye na ihe ndị dị n'okpuru akụkụ ụfọdụ; dị ka okpu egwurugwu.
