Raspberry Pi Project Ụdị bọọdụ Raspberry Pi 4 dị elu nke na-abịa na 8GB nke RAM. Ọnụ nke nhọrọ bọọdụ ọhụrụ $75. Maka ntụnyere, bọọdụ nwere 2 na 4 GB nke RAM na-ere maka $35 na $55, n'otu n'otu.
Ihe mgbawa BCM2711 a na-eji na bọọdụ ahụ na-enye gị ohere ịza ihe ruru 16 GB nke ebe nchekwa, mana mgbe emepụtara bọọdụ ahụ n'afọ gara aga, enweghị ibe LPDDR4 SDRAM dabara adaba na ere. Ugbu a Micron ewepụtala ibe 8 GB dị mkpa, na ndabere nke e wuru ụdị ọhụrụ nke Raspberry Pi 4. Nnyefe nke mgbawa 8 GB LPDDR4 SDRAM na-agba ume chọkwara obere nkwalite nke sekit ike na ịkwaga. ihe ntụgharị pulse sitere na mpaghara dị n'akụkụ njikọ USB 2.0 na mpaghara n'akụkụ USB-C.
Ka anyị cheta na osisi Raspberry Pi 4 nwere SoC BCM2711 ma gụnye 64-bit ARMv8 Cortex-A72 cores na-arụ ọrụ na 1.5GHz na VideoCore VI graphics accelerator na-akwado OpenGL ES 3.0 ma nwee ike decoding H.265 video quality 4Kp60 (ma ọ bụ 4Kp30 maka nlekota abụọ). Ejiri ebe nchekwa LPDDR4, PCI Express njikwa, Gigabit Ethernet, ọdụ ụgbọ mmiri USB 3.0 abụọ (gbakwunyere ọdụ ụgbọ mmiri USB 2.0 abụọ), ọdụ ụgbọ mmiri Micro HDMI (4K), GPIO 40-pin, DSI (njikọ ihuenyo mmetụ), CSI (igwefoto). njikọ) na mgbawa nkwukọrịta ikuku na-akwado ọkọlọtọ 802.11ac, na-arụ ọrụ na ugboro 2.4GHz na 5GHz yana Bluetooth 5.0. Enwere ike ịnye ike site na ọdụ ụgbọ USB-C (nke bụbu USB micro-B), site na GPIO ma ọ bụ site na modul PoE HAT (Power over Ethernet) nhọrọ. N'ule arụmọrụ, Raspberry Pi 4 pụtara Raspberry Pi 3B+ ugboro 2-4, yana Raspberry Pi 1 ugboro 40.
