I-Raspberry Pi Foundation ibhengeze ubukho be Inguqulelo yesine yekhompyuter encinci, iRaspberry. Inkqubo ye- Raspberry Pi 4 gcina inkangeleko efanayo kunye nexabiso lokuqala elifanayo njengangaphambili ($ 35).
Isiseko sisatsho njalo, "okokuqala, senze utshintsho olubalulekileyo ukumila kwayo ukuze ikwazi ukumelana neempawu ezintsha. ' Kuba le nguqulo intsha iphucula imigaqo kuzo zonke iindawo.
I-Raspberry Pi 4 iyafumaneka ukuqala namhlanje nge-1GB, 2GB okanye 4GB ye-RAM Ixabiso le- $ 35, $ 45 kunye ne-55, ngokulandelelana.
Iya kuxabisa i-120 yeedola e-United States, ke kwamanye amazwe umahluko unokuba ngaphezulu kancinci ngenxa yezizathu zokuhambisa.
I-Raspberry Pi 4 Iimpawu
Kule nguqulo intsha yeRaspberry Pi 4 ukuya kuthi ga kwi-4GB ye-RAM ngoku enikelwayo (amaxesha amane inqanaba layo nayiphi na iPi ngaphambi kwayo), iprosesa ekhawulezayo kunye ne-GPU, i-Ethernet ekhawulezayo, i-band-band ye-Wi-Fi, iziphumo eziphindwe kabini ze-HDMI, kunye namazibuko amabini e-USB 3.
- Ukunikezelwa kwamandla: sasuka kwi-USB micro-B saya kwi-USB-C Isinxibelelanisi samandla ethu. Oku kuxhasa i-500 mA eyongezelelweyo yamandla, iqinisekisa amandla apheleleyo e-1.2A kwizixhobo ezisezantsi ze-USB, nokuba zinomthwalo omkhulu weprosesa.
- yokuzonwabisa: Ukudibanisa imveliso yokubonisa kwindawo ekhoyo yebhodi, Ndilutshintshe udidi lwe-HDMI isinxibelelanisi (esiqhelekileyo) ngesidibanisi sohlobo lwe-HDMI ezimbini (ezincinci), olu nxibelelwano lunenkxaso ye-4K kuzo zombini iziphumo.
- I-Ethernet kunye ne-USB: igalelo lentambo ye-intanethi lihanjisiwe laya ngasekunene ukusuka ebhodini, ukuqala ngasekunene, ukwenza lula ukuhamba.
Ngelixa isinxibelelanisi se-4-pin Power-over-Ethernet (PoE) sihlala kwindawo enye, sivumela iRaspberry Pi 4 ukuba iqhubeke nokuxhasa i-PoE HAT.
Umlawuli ophambili we-SoC we-Ethernet uqhagamshelwe kwi-Broadcom PHY yangaphandle ngekhonkco le-RGMII, ebonelela ngokusebenza ngokupheleleyo.
I-USB ibonelelwa ngomlawuli we-VLI wangaphandle, oxhunywe kwindlela enye ye-PCI Express Gen 2 kunye nokubonelela nge-4 Gbps ye-bandwidth iyonke, ekwabelwana ngayo phakathi kwamazibuko amane.
Kuzo zonke ezinye izinto, ulungelelwaniso lwezihlanganisi kunye nemingxunya yokunyuka ihlala ifana, kuqinisekisa ukuhambelana neeHAT ezikhoyo kunye nezinye izixhobo.
I-Raspberry Pi 4 vs Raspberry Pi 3 Thelekisa
- Iprosesa ye-Broadcom 1,5 GHz quad-core, xa kuthelekiswa nemodeli yangaphambili ye-1,4 GHz.
- I-500 MHz yeVidiyo yeCore VI GPU, inyuka isuka kwi-400 MHz ngaphambili.
- Uhlobo lwe-C yohlobo C lwe-C yamandla, endaweni ye-USB encinci.
- Amazibuko amabini e-Micro HDMI anokukwazi ukubeka esweni ii-4K ezimbini kwi-30fps okanye esweni i-4K eyodwa kwi-60fps ngomboniso we-1080p.
- Amazibuko amabini e-USB 3 kunye namazibuko amabini e-USB 2, xa kuthelekiswa namazibuko amane e-USB 2.
- Izibuko leGigabit Ethernet elingasasebenziyo kumboniso we-USB.
- I-Bluetooth 5.0 endaweni ye-4.1.
- Ibhendi emibini 802.11ac iWi-Fi.
- Ikhadi lokugcina le-MicroSD elinobungakanani bokudlulisa ubuninzi be-50 Mbps, endaweni ye-25 Mbps.
- Isinxibelelanisi esinye se-40-pin GPIO esixhasa ezinye iindlela ezintathu; I2C, SPI kunye neUART.
Ngaba iRaspbian ilungele iRaspberry 4?
Sele sazi okuncinci malunga nezinto zeRaspberry 4 entsha, abaninzi bayazibuza kwaye iRaspbian ikulungele.
Ukuphendula kuyo, abafana abavela kwiRaspberry Pi Foundation, baya kuzisa ingxelo entsha yeRaspbian esekwe kwinguqu elandelayo yeDebian 10 Buster.
Oku kuzisa ukuphuculwa kobuchwephesha ngasemva, ujongano lomsebenzisi oluhlaziyiweyo, kunye nezicelo ezihlaziyiweyo, kubandakanya isikhangeli sewebhu seChromium 74, nokunye okuninzi.
Olu hlaziyo luthetha ukuba i-Raspberry Pi 4 inokusetyenziselwa ukubuyisela indawo kwi-PC yedesktop xa ukhetha imodeli yayo ebiza kakhulu ye-4GB.
Ngokomgangatho, ihardware iyakwazi ukuphatha uninzi lwemisebenzi yakho yemihla ngemihla, njengokukhangela kwiwebhu ukuya kuthi ga kwiithebhu ezili-15 zeChromium, ukuhlela ukukhanya kwemifanekiso kunye ne-GIMP kunye noxwebhu kunye nomsebenzi wespredishithi ngeOfisi yeLibre.
