Raspberry Pi Project Iyo yepamberi vhezheni yeRaspberry Pi 4 board inouya ne8GB ye RAM. Mutengo weiyo bhodhi sarudzo $75. Kuenzanisa, mabhodhi ane 2 uye 4 GB ye RAM anotengesa $ 35 uye $ 55, zvichiteerana.
Iyo BCM2711 chip inoshandiswa mubhodhi inokubvumira kuti utaure kusvika ku16 GB yendangariro, asi pakagadzirwa bhodhi gore rapfuura, pakanga pasina akakodzera LPDDR4 SDRAM machipisi ari kutengeswa. Iye zvino Micron aburitsa anodiwa 8 GB machipisi, pahwaro hwacho pakavakirwa shanduro itsva yeRaspberry Pi 4. Kuendeswa kwe8 GB LPDDR4 SDRAM chip chip kwaidawo kukwidziridzwa kudiki kwemaseketi emagetsi uye kufamba. iyo pulse converter kubva munzvimbo iri padyo ne USB 2.0 yekubatanidza kunzvimbo iri padyo ne USB-C.
Ngatiyeukei kuti Raspberry Pi 4 board ine SoC BCM2711 uye inosanganisira ina 64-bit ARMv8 Cortex-A72 cores inoshanda pa1.5GHz uye VideoCore VI graphics accelerator inotsigira OpenGL ES 3.0 uye inokwanisa kudhikodha H.265 vhidhiyo yemhando 4Kp60 (kana 4Kp30 yevatariri vaviri). Bhodhi racho rine LPDDR4 memory, PCI Express controller, Gigabit Ethernet, maviri USB 3.0 ports (pamwe ne USB 2.0 ports), maviri Micro HDMI (4K) ports, 40-pini GPIO, DSI (touch screen connection), CSI (kamera. kubatanidza) uye isina waya yekutaurirana chip inotsigira iyo 802.11ac standard, inoshanda pa2.4GHz uye 5GHz frequency uye Bluetooth 5.0. Simba rinogona kupihwa kuburikidza ne USB-C chiteshi (yaimbove USB micro-B), kuburikidza neGPIO kana kuburikidza neinosarudzika PoE HAT (Simba pamusoro peEthernet) module. Mukuedzwa kwekuita, Raspberry Pi 4 inodarika Raspberry Pi 3B+ ne2-4 nguva, uye Raspberry Pi 1 ne40 nguva.
