Rasipiberi Pi 4 Model B ndiye chida chaposachedwa kwambiri pamakompyuta ambiri a Raspberry Pi. Imawonjezera kuthamanga kwa purosesa, magwiridwe antchito a multimedia, kukumbukira, ndi kulumikizana poyerekeza ndi m'badwo wakale.
Raspberry Pi 3 Model B+, ndikusunga kuyanjana chakumbuyo komanso kugwiritsa ntchito mphamvu zofananira. Kwa wogwiritsa ntchito kumapeto, Raspberry Pi 4 Model B imapereka magwiridwe antchito apakompyuta ofanana ndi machitidwe a PC a x86.
Zida zazikuluzikulu za izi ndizophatikizira pulogalamu yayikulu kwambiri ya 64-bit quad-core processor, mawonetsedwe awiri pazosankha mpaka 4K kudzera pama doko a Micro-HDMI, makanema azida za hardware mpaka 4Kp60, mpaka 8GB ya RAM, iwiri -bandani 2.4 / 5.0 GHz opanda zingwe LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, ndi kutha kwa PoE (kudzera pa owonjezera a PoE HAT).
Ma LAN-band opanda zingwe ndi Bluetooth ali ndi chizindikiritso chofananira, cholola kuti bungweli likhale lopangidwa ndi zotsalira zomwe zimachepetsa kwambiri kuyesa kutsatira, kukonza mtengo komanso nthawi yogulitsa.

MACHENJEZO
Chogulitsachi chikuyenera kulumikizidwa ndi magetsi akunja omwe adavotera 5V/3A DC kapena 5.1V/3A DC Mphamvu iliyonse yakunja yomwe imagwiritsidwa ntchito ndi Raspberry Pi 4 Model B iyenera kutsatira malamulo ndi miyezo yomwe ikugwiritsidwa ntchito m'dziko lomwe akufuna. ntchito.
- Chogulitsachi chiyenera kuyendetsedwa m'malo opumira mpweya wabwino, ndipo ngati chikagwiritsidwa ntchito mkati mwa mulandu, mlanduwo suyenera kuphimbidwa.
- Chogulitsachi chiyenera kuyikidwa pamalo okhazikika, osalala, osakhazikika pomwe akugwiritsidwa ntchito ndipo sayenera kulumikizidwa ndi zinthu zoyendetsa.
- Kulumikizana kwa zida zosagwirizana ndi kulumikizana kwa GPIO kumatha kukhudza kutsatira ndikubweretsa kuwonongeka kwa chipangizocho ndikusokoneza chitsimikizo.
- Zida zonse zomwe zimagwiritsidwa ntchito ndi mankhwalawa ziyenera kutsatira miyezo yoyenera kudziko lomwe agwiritse ntchito ndikuzindikiritsidwa moyenerera kuti zitsimikizidwe kuti chitetezo ndi magwiridwe antchito zikwaniritsidwa. Zolemba izi zimaphatikizira koma sizimangokhala pamakibodi, oyang'anira ndi mbewa zikagwiritsidwa ntchito limodzi ndi Raspberry Pi.
- Pomwe zolumikizira zolumikizidwa zomwe siziphatikiza chingwe kapena cholumikizira, chingwe kapena cholumikizira chiyenera kupereka kutchinjiriza kokwanira ndi magwiridwe antchito kuti magwiridwe antchito ndi chitetezo chikwaniritsidwe.
MALANGIZO ACHITETEZO
Pofuna kupewa kuwonongeka kapena kuwonongeka kwa malonda chonde onani izi:
- Musawonetsere madzi, chinyezi kapena malo oyenda bwino mukamagwira ntchito.
- Musachiwonetsere kutentha kuchokera kulikonse; Rasipiberi Pi 4 Model B yapangidwa kuti igwire bwino ntchito kutentha kwapakati pazipinda.
- Samalani mukamayesetsa kupewa kuwonongeka kwa makina kapena magetsi ku bolodi yoyang'anira ndi zolumikizira.
- Pewani kugwira bolodi yosindikizidwa pomwe ili ndi mphamvu ndikungogwira m'mphepete kuti muchepetse kuwonongeka kwa electrostatic discharge.
Mphamvu yamagetsi yabwino ya 2.5A ingagwiritsidwe ntchito ngati zotumphukira za USB zotsika zimatsika ndi 500mA yonse.
