I-Raspberry Pi 4B: I-microcomputer encinci kwaye inamandla

Inkcazelo emfutshane:

Ingcaciso yeMveliso
Yi-motherboard ye-microcomputer esekwe kwi-ARM, isebenzisa ikhadi le-SD/MicroSD njengememori yehard disk. Kukho i-1/2/4 ujongano lwe-USB kunye ne-10/100 ye-Ethernet ujongano olujikeleze i-motherboard yekhadi (uhlobo A alunayo i-port yenethiwekhi), enokuthi idityaniswe I-Keyboard, i-mouse kunye nentambo yenethiwekhi, kunye nojongano lwemveliso ye-TV ye Iimpawu ze-analog yevidiyo kunye ne-HDMI i-high-definition video output interface. La malungu angentla adityaniswe kwi-motherboard enkulu kancinane kunekhadi letyala. Inayo yonke imisebenzi esisiseko yePC kwaye ifuna ukuqhagamshelwa kwiTV kuphela. kunye nebhodi yezitshixo, ungenza imisebenzi emininzi efana nespredishithi, ukusetyenzwa kwamagama, ukudlala imidlalo, ukudlala iividiyo ezinengcaciso ephezulu, nokunye. Imodeli yeRaspberry Pi B ibonelela kuphela ngebhodi yekhompyuter, akukho mbane wememori, ikhibhodi, i-chassis okanye unxibelelwano.

Iimpawu eziphambili zeRaspberry Pi 4B:
Isantya sokuqhubekeka esikhawulezayo:
1. I-Broadcom 2711 yamva nje ye-quad-core Cortex A72 (ARM V8-A) i-64-bit SoC iprosesa evalwe kwi-1.5GHz iphucula ukusetyenziswa kwamandla; kunye ne-thermals kwi-Pi 4 + B ithetha ukuba i-CPU kwi-BCM2837 SoC ngoku inokuthi iqhube kwi-1.5 GHz Yimpucuko ye-20% ngaphezu kwemodeli yangaphambili ye-Pi 3, ebaleka kwi-1.2GHz.
2. Ukusebenza kwevidiyo kwi-Pi 4 B kuphuculwe ngenkxaso ye-monitor ephindwe kabini kwizigqibo ukuya kwi-4K ngokusebenzisa iperi yezibuko; i-hardware yevidiyo i-decoding ukuya kwi-4Kp60, inkxaso ye-H 265 decoding (4kp 60); I-H.264 kunye ne-MPEG-4 decoding (1080p60).

I-wireless ekhawulezayo:
1. Xa kuthelekiswa nomzekelo wePi 3 yangaphambili, utshintsho oluphawulekayo kwi-Pi 4 B kukubandakanywa kwentsha, ngokukhawuleza; I-chip ye-wireless chip exhasa i-802.11 b/g/n/ac LAN engenazingcingo.
2. I-Dual-band 2.4GHz kunye ne-5GHz i-LAN engenazintambo isekela uqhagamshelwano olukhawulezayo lwenethiwekhi kunye nokuphazamiseka okuncinci, kunye neteknoloji entsha ye-antenna ye-PCB isekela ulwamkelo olungcono.
3. I-5.0 yamva nje ikuvumela ukuba usebenzise ikhibhodi engenazingcingo / i-trackpad enoluhlu oluninzi kunangaphambili, ngaphandle kwee-dongles ezongezelelweyo; igcina izinto zicocekile.

Uqhagamshelo lwe-Ethernet eyongeziweyo:
1. I-Pi 4 B inothungelwano lweengcingo olukhawuleza kakhulu, olunobuchwepheshe be-USB 3.0; enkosi kwi-chip ephuculweyo ye-USB/LAN; kufuneka ubone isantya ukuya kumaxesha ali-10 ngokukhawuleza kunemifuziselo yePi yangaphambili.
2. Intloko yeGPIO ihlala injalo, izikhonkwane ezingama-40; umva ngokupheleleyo iyahambelana neebhodi zangaphambili, njengeemodeli ezintathu zokuqala zePi. Nangona kunjalo; kufuneka kuqatshelwe ukuba iiplagi ze-PoE ezintsha zinokudibana namacandelo angaphantsi kwee-caps ezithile; ezifana neminqwazi yomnyama.
