Raspberry Pi 4B: Gitoya kandi ikomeye microcomputer Ishusho Yerekanwe

Raspberry Pi 4B: Microcomputer ntoya kandi ikomeye

Ibisobanuro bigufi:

ibisobanuro ku bicuruzwa
Nububiko bwa microcomputer bushingiye kuri ARM, ukoresheje ikarita ya SD / MicroSD nka disiki yibuka. Hano hari 1/2/4 USB interineti hamwe na 10/100 ya Ethernet ya interineti ikikije ikarita yububiko (ubwoko A ntabwo ifite icyambu), ishobora guhuzwa na Mwandikisho, imbeba numuyoboro wa neti, kimwe na interineti isohoka kuri TV. amashusho yerekana amashusho hamwe na HDMI ibisobanuro bihanitse byerekana amashusho. Ibice byavuzwe haruguru byose byahujwe kububiko bwa mama bunini cyane kuruta ikarita yinguzanyo. Ifite imirimo yose yibanze ya PC kandi igomba gusa guhuzwa na TV. na clavier, urashobora gukora imirimo myinshi nkurupapuro, gutunganya ijambo, gukina imikino, gukina amashusho asobanutse neza, nibindi byinshi. Moderi ya Raspberry Pi B itanga gusa ikibaho cya mudasobwa, nta mashanyarazi yibuka, clavier, chassis cyangwa amahuza.

Umuyoboro winsinga: True Gigabit Ethernet (icyambu gishobora kugerwaho
Ethernet poe: Ethernet ikoresheje HAT yinyongera

Ibyingenzi byingenzi bya Raspberry Pi 4B:
Umuvuduko wo gutunganya vuba:
1. Broadcom 2711 iheruka kwaduka Cortex A72 (ARM V8-A) 64-bit ya SoC itunganya amasaha 1.5GHz itezimbere gukoresha ingufu; hamwe nubushyuhe kuri Pi 4 + B bivuze ko CPU kuri BCM2837 SoC ishobora noneho gukora kuri 1.5 GHz Ibyo ni iterambere rya 20% ugereranije na moderi ya Pi 3 yabanjirije iyi, yakoraga kuri 1.2GHz.
2. Imikorere ya videwo kuri Pi 4 B yazamuwe hifashishijwe inkunga ya monitor ebyiri ku myanzuro igera kuri 4K ikoresheje ibyambu; videwo yerekana ibyuma bigera kuri 4Kp60, inkunga ya H 265 (4kp 60); H.264 na MPEG-4 decoding (1080p60).

Umuyoboro wihuse:
1. Ugereranije nicyitegererezo cyambere Pi 3, impinduka zikomeye muri Pi 4 B nugushiramo ibishya, byihuse; ibyuma bibiri-bidafite chip bifasha 802.11 b / g / n / ac LAN idafite umugozi.
2. Dual-band 2.4GHz na 5GHz idafite umugozi LAN ishyigikira imiyoboro yihuta yihuta itabangamiye, kandi tekinoroji nshya ya PCB antenna ishyigikira kwakira neza.
3. Iheruka 5.0 igufasha gukoresha clavier idafite umurongo / trackpad ifite intera irenze iyambere, nta dongles ziyongera; ituma ibintu bigenda neza.

Kongera umurongo wa Ethernet:
1. Pi 4 B ifite imiyoboro yihuta cyane, hamwe na USB 3.0; dukesha chip ya USB / LAN yazamuye; ugomba kubona umuvuduko wikubye inshuro 10 kurenza moderi zabanjirije Pi.
2. Umutwe wa GPIO ukomeza kuba umwe, pin 40; gusubira inyuma rwose bihuye nibibaho byababyeyi, nka moderi eshatu za mbere za Pi. Ariko; twakagombye kumenya ko amacomeka mashya ya PoE ashobora guhura nibice biri munsi yimitwe imwe; nk'umukororombya.
