Raspberry Pi yaive chimurenga pamakomputa emutengo wakaderera. Iwe unogona kuve neSBC yeinosvika € 30 nemikana mikuru. Vagadziri uye chikamu chedzidzo ndivo vari vaviri vakanyanya kubatsirwa. Pane zvakawanda zve DIY zvirongwa zvekuita neimwe yemabhodhi akadhura, uye iwe unogona kudzidza zvakawanda kubva kwavari, senge mashandisiro emakomputa makuru nekugadzira iyo Raspis masango ...
Zvakanaka ikozvino Raspberry Pi Foundation yagadzirisa zvigadzirwa zvayo. Pane bhodhi idzva kunze, iyo Raspberry Pi 4. Iyi SBC (Imwe Bhodhi Komputa) yakabudirira mushure mekubudirira kweRaspi, uye vamwe vazhinji vagadziri vakatora mukana weiyo wave kugadzira mabhodhi avo akafanana neyekutanga kana neimwe shanduko, kuita kuri nani, mashandiro matsva, nezvimwe. Raspberry Original Pi achiri mambokadzi.
Pamusoro pe $ 35 kana € 35, unogona tenga iyo itsva Raspberry Pi 4 Muenzaniso B. Zvichida kuti mamwe emhando dzinotora dzichaonekwa zvakare munguva pfupi, sezvazvakaitika kune avo vakavatangira. Iwe ikozvino une USB-C socket yemagetsi, 2x micro HDMI chiteshi nerutsigiro rweviri 4K monitors kana maonesheni, 2x USB 2.0 uye 2x USB 3.0 zviteshi, zvakare chiteshi cheEthernet. Zvimwe zvinhu zvakaita se40 GPIO zvinochengeterwa mapurojekiti ako.
Kana zvakadaro RAM ndangariro, ikozvino unogona kusarudza pakati penzvimbo dzakasiyana ne1, 2 uye 4 GB. Iyo yekugadzirisa chip yakatsiviwa neimwe ine simba. Kashoma kuti ivo vasarudze kubvisa iyo RAM kubva kuSoC ... kupa mukana wekusarudza pakati penzvimbo dzinoverengeka nepo ichichengeta imwecheteyo SoC SPEC, asi chokwadi ndechekuti izano rakanaka kugutsa zvakasiyana zvinodikanwa zve vashandisi.
Iyo yepakati chip yave ikozvino Broadcom BCM2711 ine ARM Cortex-A72 CPU pa1.5 Ghz uye ina cores kugadzira. Inobatanidza zvakare ine simba GPU, ine rutsigiro rwe4K uye vanovimbisa kutsigira H.265 multimedia ye4K60p, H.264 1080p60 uye 1080p30, inowirirana neiyo OpenGL ES 3.0 mifananidzo API. Saka iwe unogona kutarisira kwakawanda kuita uye kugona kumhanyisa iyo hombe nhamba yekugovera uye masisitimu anoshanda aripo.
