Iprojekthi yeRaspberry Pi Inguqulelo ephucukileyo yebhodi yeRaspberry Pi 4 eza ne-8GB ye-RAM. Iindleko zokhetho lwebhodi entsha $75. Ukuthelekisa, iibhodi ezine-2 kunye ne-4 GB ye-RAM zithengisa i-$ 35 kunye ne-$ 55, ngokulandelanayo.
I-chip ye-BCM2711 esetyenziswe ebhodini inokujongana ne-16 GB yememori, kodwa xa ibhodi yaphuhliswa kunyaka odlulileyo, ii-chips ze-LPDDR4 SDRAM ezifanelekileyo azizange zithengiswe. Ngoku iMicron ikhuphe iitshiphusi eziyimfuneko ze-8 GB, ngesiseko sayo inguqulelo entsha yeRaspberry Pi 4. Ukuhanjiswa kwe-chip ye-8 GB LPDDR4 SDRAM chip nayo ifuna ukuphuculwa okuncinci kweesekethe zamandla kunye nokuhamba. isiguquli se-pulse ukusuka kwindawo esecaleni kwe-USB 2.0 izihlanganisi ukuya kwindawo esecaleni kwe-USB-C.
Masikhumbule ukuba ibhodi yeRaspberry Pi 4 ixhotyiswe nge-SoC BCM2711 kwaye ibandakanya ii-cores ezine ze-64-bit ARMv8 Cortex-A72 ezisebenza kwi-1.5GHz kunye ne-VideoCore VI ye-accelerator yemizobo exhasa i-OpenGL ES 3.0 kwaye iyakwazi ukucacisa umgangatho wevidiyo ye-H.265 4Kp60 (okanye 4Kp30 yeemonitha ezimbini). Ibhodi ixhotyiswe ngememori ye-LPDDR4, isilawuli se-PCI Express, i-Gigabit Ethernet, izibuko ezimbini ze-USB 3.0 (kunye nezibuko ezimbini ze-USB 2.0), izibuko ezimbini ze-Micro HDMI (4K), i-40-pin GPIO, i-DSI (uxhulumaniso lwesikrini sokuthinta), i-CSI (ikhamera uqhagamshelo) kunye netshiphu yonxibelelwano engenazingcingo exhasa umgangatho we-802.11ac, osebenza kwi-2.4GHz kunye ne-5GHz frequencies kunye ne-Bluetooth 5.0. Amandla anokunikezelwa nge-USB-C port (ngaphambili USB micro-B), nge-GPIO okanye nge-PoE HAT ekhethiweyo (Amandla phezu kwe-Ethernet) imodyuli. Kwiimvavanyo zokusebenza, iRaspberry Pi 4 idlula iRaspberry Pi 3B + ngamaxesha angama-2-4, kunye neRaspberry Pi 1 ngamaxesha angama-40.
