Mahaifiyar mahaifa ce ta microcomputer bisa ARM, ta amfani da katin SD/MicroSD azaman faifan ƙwaƙwalwar ajiya. Akwai 1/2/4 USB musaya da kuma 10/100 Ethernet dubawa a kusa da katin motherboard (nau'in A ba shi da tashar tashar jiragen ruwa), wanda za a iya haɗa Keyboard, linzamin kwamfuta da kuma cibiyar sadarwa na USB, kazalika da TV fitarwa dubawa ga. siginar analog na bidiyo da babban ma'anar fitarwa na bidiyo na HDMI. Abubuwan da ke sama duk an haɗa su akan motherboard wanda ya ɗan fi girma fiye da katin kiredit. Yana da duk mahimman ayyukan PC kuma kawai yana buƙatar haɗawa da TV. da madannai, kuna iya yin ayyuka da yawa kamar maƙunsar rubutu, sarrafa kalmomi, kunna wasanni, kunna bidiyo mai ma'ana, da ƙari. Samfurin Rasberi Pi B yana ba da allon kwamfuta kawai, babu wutar lantarki, madannai, chassis ko haɗi.

Mabuɗin fasali na Rasberi Pi 4B:
Saurin sarrafawa:
1. Sabon Broadcom 2711 quad-core Cortex A72 (ARM V8-A) 64-bit SoC processor wanda aka rufe a 1.5GHz yana inganta amfani da wutar lantarki; da thermals akan Pi 4+B yana nufin cewa CPU akan BCM2837 SoC na iya aiki yanzu a 1.5 GHz Wannan shine haɓaka 20% akan ƙirar Pi 3 da ta gabata, wacce ke gudana a 1.2GHz.
2. Ayyukan bidiyo akan Pi 4 B an haɓaka su tare da tallafin duba dual a ƙuduri har zuwa 4K ta hanyar tashar jiragen ruwa guda biyu; Ƙididdigar bidiyo na hardware har zuwa 4Kp60, goyon baya don ƙaddamarwa H 265 (4kp 60); H.264 da MPEG-4 dikodi (1080p60).

Mara waya mafi sauri:
1. Idan aka kwatanta da samfurin Pi 3 na baya, babban canji a cikin Pi 4 B shine haɗa sabon, sauri; guntu mara waya ta dual-band wanda ke goyan bayan 802.11 b/g/n/ac mara waya ta LAN.
2. Dual-band 2.4GHz da 5GHz LAN mara igiyar waya tana goyan bayan haɗin yanar gizo mai sauri tare da ƙarancin tsangwama, kuma sabuwar fasahar eriya ta PCB tana tallafawa mafi kyawun liyafar.
3. Sabon 5.0 yana ba ku damar amfani da madannai / waƙa mara waya tare da ƙarin kewayo fiye da da, ba tare da ƙarin dongles ba; yana gyara abubuwa.

Ingantaccen haɗin Ethernet:
1. Pi 4 B yana da mahimman hanyoyin sadarwar waya da sauri, tare da fasahar USB 3.0; godiya ga ingantaccen guntu na USB / LAN; yakamata ku ga saurin gudu har sau 10 fiye da samfuran Pi na baya.
2. Shugaban GPIO ya kasance iri ɗaya, 40 fil; cikakken baya mai jituwa tare da uwayen uwa na baya, kamar nau'ikan Pi guda uku na farko. Duk da haka; ya kamata a lura cewa sababbin matosai na PoE na iya shiga cikin hulɗa tare da sassan da ke ƙarƙashin wasu iyakoki; irin su hular bakan gizo.
