I-Raspberry Pi 4 Model B: izici ezintsha

I-Raspberry Pi inethoyizi elisha elithengiswayo. Imayelana ne- imodeli entsha Raspberry Pi 4 Model B okucishe kwamangala, ngoba lokhu kwethulwa bekungalindelekile. Kubukeka sengathi izindaba zizoza ngonyaka we-2020, kepha sezithuthukile. Leli bhodi le-SBC (i-Single Board Computer) liphumelele kakhulu hhayi ngengozi. Ngamanani azungeze i- € 30 unekhompyutha elula yokwenza amaphrojekthi amaningi.

Lokho kuguqule iRaspi yaba yi uqweqwe lwempumelelo phakathi kwabenzi abathanda i-DIY nasemkhakheni wezemfundo, ngoba ngenxa yemibhalo yayo emihle nenani lezifundo ezikhona, sekuyithuluzi elihle lokufunda ngentengo engabizi kakhulu yezikole nezikhungo zemfundo. Ngemuva kwezinyanga singatholi sibuyekezo, manje sesinayo le Rapsberry Pi 4. entsha ngabe ufuna ukwazi ukuthi yini entsha?

I-Raspberry Pi 4 Model B entsha ine- ihadiwe enamandla kakhulu nge- € 35. Kuyo, ungasebenzisa inamba enkulu yezinhlelo zokusebenza noma ukwabiwa ongasebenza ngakho ngokuya ngezidingo zakho futhi wenze amaphrojekthi amaningi ngenxa yezengezo ezisemakethe kanye nama-GPIO ayo angama-40. Uma ufuna ukwazi ngokuningiliziwe i-hardware nezimpawu zayo zobuchwepheshe yilezi:

• I-Broadcom BCM2711 SoC, kepha yize kujwayele ukuthi lawa machips ahlanganise ne-RAM, yize kulokhu kungenjalo. Okubandakanyayo i-GPU enamandla kakhulu esekela i-OpenGL ES 3.0, ukwesekwa kwemultimedia H.265 ye-4K 60 FPS, H.264 ye-1080p60 ne-1080p30 fps. I-CPU manje seyi-quad-core ARM Cortex-A72 ne-1.5 Ghz.
• La I-RAM ifakwe kwi-chip ehlukile, nethuba lokukhetha phakathi kuka-1, 2 no-4GB. Ukushiya i-RAM ngaphandle, kulula ukwenza ibhodi elifanayo bese ufaka esikhundleni se-RAM chip ukunikela ngokuhlukahluka okuningana.
• Ngokuqondene ne ukuxhumana, nayo ithuthukisiwe. Ine-USB-C yamandla, amachweba ama-2 micro HDMI, amachweba ama-2 USB 2.0 namanye amachweba ama-2 USB 3.0, ngaphezu kwe-Ethernet neJack ngomsindo. Vele kunjalo, inesifundi sekhadi le-Micro SD, i-GPIO, nokunye ukuxhumana kwamagajethi njengemodyuli yekhamera, njll.
