I-Raspberry Pi yayiyinguqu kwiikhompyutha ezibiza ixabiso eliphantsi. Unokuba ne-SBC ejikeleze i-30 euros enamandla amakhulu. Abenzi kunye necandelo lezemfundo lelona lezona zibini zixhamle kakhulu. Zininzi iiprojekthi ze-DIY zokwenza nenye yeebhodi ezingabizi kakhulu, kwaye ungafunda okuninzi kubo, njengokusebenza kweekhompyuter ngokwenza iklasta yeRaspis ...
Ewe ngoku iRaspberry Pi Foundation iye yahlaziya izixhobo zayo. Nazi ibhodi entsha ngaphandle, iRaspberry Pi 4. Le SBC (iKhompyuter yeBhodi eNye) ichume emva kwempumelelo yeRaspi, kwaye uninzi lwabanye abavelisi basebenzise ithuba lokuzenzela iibhodi ezifanayo nezokuqala okanye notshintsho oluthile, ukusebenza ngcono, ukusebenza okutsha, njl. I-Raspberry Original Pi isengukumkanikazi.
Malunga $ 35 okanye i- € 35, uthanda thenga iRaspberry Pi 4 Model B entsha. Kungenzeka ukuba ezinye iimodeli ezivela kwezinye ziya kuvela kungekudala, njengoko kwenzekile nakwabo bangaphambili. Ngoku unesokethi ye-USB-C yamandla, 2x amazibuko amancinci e-HDMI ngenkxaso yeemonitha ezimbini ze-4K okanye imiboniso, i-2x i-USB 2.0 kunye ne-2x ye-USB 3.0, kunye nezibuko le-Ethernet. Ezinye izinto ezinje nge-40 GPIO zigcinelwe iiprojekthi zakho.
Ewe Imemori ye-RAM, Ngoku unokukhetha phakathi kwamandla ahlukeneyo nge-1, 2 kunye ne-4 GB. Inkqubo yokulungisa iye yathathelwa indawo yenye enamandla ngakumbi. Kunqabile ukuba bakhethe ukususa i-RAM kwi-SoC ... ukunika ithuba lokukhetha phakathi kwezinto ezininzi ngelixa begcina i-SoC SPEC efanayo, kodwa inyani kukuba licebo elihle ukwanelisa iimfuno ezahlukeneyo ze abasebenzisi.
I-chip chip ngoku I-Broadcom BCM2711 ene-ARM Cortex-A72 CPU kwi-1.5 Ghz kunye neekhoresi ezine ukwenza. Ikwadibanisa i-GPU enamandla ngakumbi, ixhasa i-4K kwaye ithembisa ngenkxaso ye-H.265 multimedia ye-4K60p, H.264 1080p60 kunye ne-1080p30, ehambelana ne-OpenGL ES 3.0 yemizobo ye-API. Ke unokulindela ukusebenza ngakumbi kunye nokukhawuleza ukuqhuba inani elikhulu leenkqubo zokusebenza ezikhoyo kunye nolwabiwo.
