Mashruuca Raspberry Pi Nooc horumarsan oo ah guddiga Raspberry Pi 4 oo la socda 8GB ee RAM. Qiimaha doorashada guddiga cusub $75. Marka la barbardhigo, looxyada leh 2 iyo 4 GB ee RAM waxay iibiyaan $35 iyo $55, siday u kala horreeyaan.
Chip-ka BCM2711 ee looxa loo isticmaalo waxa uu wax ka qaban karaa ilaa 16 GB oo xusuusta ah, laakiin markii guddiga la sameeyay sannadkii hore, chips-ka LPDDR4 SDRAM ee ku habboon looma helin iib. Hadda Micron waxay soo saartay 8 GB chips lagama maarmaanka u ah, taas oo ku saleysan nooca cusub ee Raspberry Pi 4. Soo gudbinta tamar aad u xoog badan oo 8 GB LPDDR4 SDRAM ah ayaa sidoo kale u baahday wax yar hagaajinta wareegyada korantada iyo dhaqaaqa beddelka garaaca wadnaha ee aagga ku xiga isku xirka USB 2.0 ee aagga ku xiga USB-C.
Aynu xasuusanno in guddiga Raspberry Pi 4 ay ku qalabaysan yihiin SoC BCM2711 oo ay ku jiraan afar 64-bit ARMv8 Cortex-A72 cores oo ka shaqeeya 1.5GHz iyo VideoCore VI garaafyada xawaaraha taageeraya OpenGL ES 3.0 oo awood u leh inuu dejiyo H.265 tayada muuqaalka 4Kp60 (ama 4Kp30 ee laba kormeerayaal). Guddidu waxay ku qalabaysan tahay xusuusta LPDDR4, kontoroolka PCI Express, Gigabit Ethernet, laba dekedood oo USB 3.0 ah (oo lagu daray laba dekedood oo USB 2.0 ah), laba dekedaha Micro HDMI (4K), 40-pin GPIO, DSI (xidhiidhka shaashadda taabashada), CSI (camera) isku xirka) iyo chip isgaarsiinta wireless taageeraya heerka 802.11ac, ka shaqeeya 2.4GHz iyo 5GHz soo noqnoqda iyo Bluetooth 5.0. Awoodda waxaa lagu bixin karaa iyada oo loo sii marayo dekedda USB-C (oo hore u ahayd USB micro-B), iyada oo loo sii marayo GPIO ama iyada oo loo marayo moduleka PoE HAT (Power over Ethernet). Imtixaannada waxqabadka, Raspberry Pi 4 ayaa ka sarreeya Raspberry Pi 3B+ 2-4 jeer, iyo Raspberry Pi 1 40 jeer.
