Iphrojekthi ye-Raspberry Pi Inguqulo ethuthukisiwe yebhodi le-Raspberry Pi 4 eliza ne-8GB ye-RAM. Izindleko zenketho yebhodi entsha $75. Ukuze uqhathanise, amabhodi ane-2 kanye ne-4 GB ye-RAM athengisa nge-$35 ne-$55, ngokulandelana.
I-chip ye-BCM2711 esetshenziswe ebhodini ikuvumela ukuthi ubhekane nenkumbulo efika ku-16 GB, kodwa lapho ibhodi lakhiwa ngonyaka odlule, ayengekho ama-chips e-LPDDR4 SDRAM afanelekile athengiswayo. Manje uMicron usekhiphe ama-chips angu-8 GB adingekayo, okusekelwe kuwo inguqulo entsha ye-Raspberry Pi 4. Ukulethwa kwe-chip ye-8 GB LPDDR4 SDRAM ye-SDRAM edinga amandla amaningi kuphinde kwadinga ukuthuthukiswa kancane kwamasekhethi amandla kanye nokunyakaza. isiguquli se-pulse ukusuka endaweni eseduze nezixhumi ze-USB 2.0 ukuya endaweni eseduze ne-USB-C.
Masikhumbule ukuthi ibhodi le-Raspberry Pi 4 lifakwe i-SoC BCM2711 futhi lihlanganisa ama-cores amane we-64-bit ARMv8 Cortex-A72 asebenza ku-1.5GHz kanye nesisheshisi sezithombe ze-VideoCore VI esisekela i-OpenGL ES 3.0 futhi ekwazi ukuqopha ikhwalithi yevidiyo ye-H.265 engu-4Kp60 (noma i-4Kp30 yamamonitha amabili). Ibhodi ifakwe inkumbulo ye-LPDDR4, isilawuli se-PCI Express, i-Gigabit Ethernet, izimbobo ezimbili ze-USB 3.0 (kanye nezimbobo ezimbili ze-USB 2.0), izimbobo ezimbili ze-Micro HDMI (4K), i-GPIO yamaphini angu-40, i-DSI (uxhumano lwesikrini sokuthinta), i-CSI (ikhamera uxhumano) ne-chip yokuxhumana engenantambo esekela izinga le-802.11ac, esebenza kumafrikhwensi angu-2.4GHz kanye no-5GHz kanye ne-Bluetooth 5.0. Amandla anganikezwa ngembobo ye-USB-C (ngaphambilini eyayiyi-USB micro-B), nge-GPIO noma ngemojula ye-PoE HAT (Amandla phezu kwe-Ethernet) ozikhethela yona. Ezivivinyweni zokusebenza, i-Raspberry Pi 4 idlula i-Raspberry Pi 3B+ izikhathi ezingu-2-4, kanye ne-Raspberry Pi 1 izikhathi ezingu-40.
