Rasberi Pi Project Wani ci gaba na allon Raspberry Pi 4 wanda ya zo tare da 8GB na RAM. Farashin sabon zaɓin hukumar $75. Don kwatanta, allunan da ke da 2 da 4 GB na RAM suna sayar da $35 da $55, bi da bi.
Chip ɗin BCM2711 da aka yi amfani da shi a cikin allo yana ba ku damar yin magana har zuwa 16 GB na ƙwaƙwalwar ajiya, amma lokacin da aka haɓaka allon a bara, babu wani guntuwar LPDDR4 SDRAM masu dacewa akan siyarwa. Yanzu Micron ya fitar da kwakwalwan kwamfuta masu mahimmanci na 8 GB, wanda aka gina sabon sigar Raspberry Pi 4. Isar da guntu mai ƙarfi 8 GB LPDDR4 SDRAM mai ƙarfi shima yana buƙatar haɓaka kaɗan na da'irori na wutar lantarki da motsi. mai jujjuya bugun jini daga yankin kusa da masu haɗin USB 2.0 zuwa yankin kusa da USB-C.
Mu tuna cewa kwamitin Rasberi Pi 4 yana sanye da SoC BCM2711 kuma ya haɗa da 64-bit ARMv8 Cortex-A72 cores da ke aiki a 1.5GHz da VideoCore VI graphics accelerator wanda ke goyan bayan OpenGL ES 3.0 kuma yana da ikon ƙaddamar da ingancin bidiyo na H.265 4Kp60 (ko 4Kp30 don masu saka idanu biyu). Jirgin yana sanye da ƙwaƙwalwar LPDDR4, mai sarrafa PCI Express, Gigabit Ethernet, tashoshin USB 3.0 guda biyu (da tashoshin USB na 2.0 guda biyu), tashoshin Micro HDMI (4K), GPIO 40-pin, DSI (haɗin allo), CSI (kyamara). haɗi) da guntu sadarwar sadarwa mara waya mai goyan bayan ma'aunin 802.11ac, yana aiki a mitoci 2.4GHz da 5GHz da Bluetooth 5.0. Ana iya ba da wutar lantarki ta tashar USB-C (a da USB micro-B), ta GPIO ko ta hanyar zaɓin PoE HAT (Power over Ethernet). A cikin gwaje-gwajen aiki, Rasberi Pi 4 ya fi Rasberi Pi 3B+ da sau 2-4, kuma Rasberi Pi 1 ta sau 40.
