Raspberry Pi 4 Umzekelo B

I-Raspberry Pi inento entsha yokudlala. Imalunga nayo Imodeli entsha yeRaspberry Pi 4 Imodeli B othe waphantse wothuka, kuba olu phehlelelo belingalindelwanga. Kubonakala ngathi iindaba ziya kuza nge-2020, kodwa ziye zaqhubela phambili. Le bhodi ye-SBC (yeKhompyuter yeBhodi enye) iphumelele kakhulu kwaye ayenzekanga ngamabona-ndenzile. Ngexabiso elijikeleze i- € 30 unekhompyuter elula onokuqhuba ngayo uninzi lweeprojekthi.

Oko kuguqule iRaspi yaba I-plaque yempumelelo phakathi kwabenzi abathanda i-DIY nakwicandelo lezemfundo, ukusukela ngenxa yamaxwebhu ayo alungileyo kunye nenani lezifundo ezikhoyo, ibe sisixhobo esihle sokufunda ngexabiso elifikelelekayo kakhulu kwizikolo nakumaziko emfundo. Emva kweenyanga ngaphandle kokufumana uhlaziyo, ngoku sinayo le Rapsberry Pi 4. entsha Ngaba uyafuna ukwazi ukuba yintoni entsha?

Imodeli entsha yeRaspberry Pi 4 B inefayile ye- izixhobo ezinamandla ngakumbi ze- € 35. Kuyo uya kuba nakho ukuqhuba inani elikhulu leenkqubo ezisebenzayo okanye ulwabiwo oza kusebenza ngalo ngokweemfuno zakho kwaye wenze iiprojekthi ezininzi ngenxa yezongezo kwintengiso kunye nee-GPIO zayo ezingama-40. Ukuba ufuna ukwazi nzulu izixhobo zayo kunye neempawu zobuchwephesha zezi:

  • Isasazo BCM2711 SoC, Kodwa nangona ngesiqhelo ezi chips zidibanisa i-RAM, nangona kule meko ingafani naleyo. Oko kubandakanya i-GPU enamandla ngakumbi exhasa i-OpenGL ES 3.0, inkxaso ye-multimedia H.265 ye-4K 60 FPS, H.264 ye-1080p60 kunye ne-1080p30 fps. I-CPU ngoku iyi-quad-core ARM Cortex-A72 kunye ne-1.5 Ghz.
  • La I-RAM ifakwe kwichip eyahlukileyo, kunye nokukhetha ukukhetha phakathi kwe-1, 2 kunye ne-4GB. Ukushiya i-RAM ngaphandle, kulula ukwenza ibhodi enye kunye nokutshintsha kuphela i-chip ye-RAM ukubonelela ngeendlela ezahlukeneyo.
  • Ngokuphathelele uqhagamshelo, nayo iphuculwe. Ine-USB-C yamandla, 2 amazibuko amancinci e-HDMI, amazibuko ama-2 e-USB kunye nezinye izibuko ezi-2.0 ze-USB 2, ukongeza kwi-Ethernet kunye neJack yesandi. Ewe ikwanomfundi wekhadi le-SD encinci, i-GPIO, kunye nolunye unxibelelwano lwezixhobo ezinjengemodyuli yekhamera, njl.

    Ndisebenzise iRaspbian kwiPi 3b, eyona nkqubo isebenze kakhulu, kwaye yayihamba kancinci njengofudo njengoko i-1GB ye-RAM yayiyeyona bhotile iphambili.

    Ngokunyuka kweRam kusebenza nje njengepc encinci kunye neLinux.
