IRaspberry Pi Foundation isimemezele ukutholakala kwefayela le- inguqulo yesine yekhompyutha ephaketheni elincane, i-Raspberry. I- Ukusajingijolo Pi 4 gcina ukubukeka okufanayo kanye nentengo yokuqala efanayo neyokuqala kwayo ($ 35).
Isisekelo sisasho njalo ukuthi, “okokuqala ngqa, senze ushintsho olubalulekile ngesimo sayo sokuzivumelanisa nezici ezintsha. ' Njengoba le nguqulo entsha ithuthukisa ukucaciswa kuzo zonke izindawo.
I-Raspberry Pi 4 iyatholakala kusukela namuhla nge-1GB, 2GB noma i-4GB ye-RAM ngentengo ku- $ 35, $ 45 naku- $ 55, ngokulandelana.
Kuzobiza u- $ 120 e-United States, ngakho-ke kwamanye amazwe okuhlukile kungaphakama kancane ngezizathu zokuthumela.
Izici ze-Raspberry Pi 4
Kule nguqulo entsha ye-Raspberry Pi 4 kuze kufike ku-4GB RAM manje enikelwayo (izikhathi ezine isilinganiso sanoma iyiphi iPi ngaphambi kwayo), iprosesa esheshayo ne-GPU, i-Ethernet esheshayo, i-dual-band Wi-Fi, imiphumela ephindwe kabili ye-HDMI, namachweba amabili e-USB 3.
- Ukunikezwa kwamandla: sisuke ku-USB micro-B saya ku-USB-C yesixhumi sethu samandla. Lokhu kusekela i-500 mA eyengeziwe yamandla, iqinisekisa inani eliphelele le-1.2A yamadivayisi we-USB esezansi, noma ngabe inomthwalo omkhulu weprosesa.
- Ividiyo: Ukuhlanganisa okukhiphayo okubonisa okumbili esikhaleni sebhodi esivele sikhona, Ngishintshe isixhumi sohlobo lwe-HDMI (esijwayelekile) ngezixhumi ezimbili zohlobo lwe-HDMI D (micro), lokhu kuxhumana kunokusekelwa kwe-4K kukho konke okuphumayo.
- I-Ethernet ne-USB: okokufaka kwekhebula le-inthanethi kuhanjiswe kwesokudla ngaphezulu kusuka ebhodini, kusukela kwesokudla, kwenza umzila ube lula kakhulu.
Ngenkathi isixhumi se-4-pin Power-over-Ethernet (PoE) sihlala endaweni eyodwa, sivumela i-Raspberry Pi 4 ukuthi iqhubeke nokuxhasa i-PoE HAT.
Isilawuli esikhulu se-SoC Ethernet sixhunywe kwi-Broadcom PHY yangaphandle ngesixhumanisi se-RGMII esizinikele, esihlinzeka ngokusebenza okugcwele.
I-USB inikezwa ngesilawuli se-VLI sangaphandle, esixhunywe kulayini owodwa we-PCI Express Gen 2 futhi sihlinzeka nge-4 Gbps yomkhawulokudonsa ophelele, owabiwe phakathi kwamachweba amane.
Kuzo zonke ezinye izici, ukuhlelwa kwezixhumi nezimbobo ezihlanganayo kuhlala kunjalo, kuqinisekisa ukuhambisana nama-HAT akhona nezinye izesekeli.
I-Raspberry Pi 4 vs Raspberry Pi 3 Ukuqhathanisa
- I-Broadcom 1,5 GHz quad-core processor, uma kuqhathaniswa nemodeli yangaphambilini ye-1,4 GHz.
- I-500 MHz VideoCore VI GPU, isuka ku-400 MHz ngaphambilini.
- Imbobo ye-USB Type-C yamandla, esikhundleni se-USB encane.
- Amachweba amabili e-Micro HDMI akwazi ukunika amandla ama-monitor angama-4K angama-30fps noma i-monitor eyodwa ye-4K kuma-60fps ngesibonisi se-1080p.
- Izimbobo ezimbili ze-USB 3 namachweba amabili e-USB 2, uma kuqhathaniswa namachweba amane e-USB 2.
- Imbobo ye-Gigabit Ethernet engasenqunyelwe i-interface ye-USB.
- I-Bluetooth 5.0 esikhundleni se-4.1.
- I-Dual-band 802.11ac Wi-Fi.
- Ikhadi lokugcina le-microSD elinesilinganiso sokudlulisa esiphezulu sama-50 Mbps, esikhundleni sama-25 Mbps.
- Isixhumi esisodwa se-GPIO esingu-40 esisekela ezinye izixhumi ezintathu; I2C, SPI ne-UART.
Ngabe iRaspbian ilungele i-Raspberry 4?
Njengoba sesivele sazi okuncane ngezakhi ze-Raspberry 4 entsha, abaningi bazozibuza futhi iRaspbian isilungele.
Ukuphendula kuso, abafana abavela eRaspberry Pi Foundation, bazoletha uhlobo olusha lweRaspbian olususelwa kunguqulo elandelayo yeDebian 10 Buster.
Lokhu kuletha ukuthuthuka okuningi kwezobuchwepheshe ngemuva, isikhombimsebenzisi somuntu wesimanje kakhulu, nezinhlelo zokusebenza ezibuyekeziwe, kufaka phakathi isiphequluli sewebhu seChromium 74, nokunye okuningi.
Lezi zibuyekezo zisho ukuthi i-Raspberry Pi 4 ingasetshenziswa njengokufaka esikhundleni se-PC yedeskithophu yesabelomali uma ukhetha imodeli yayo ebiza kakhulu ye-4GB.
Ngokwesilinganiso, i-hardware iyakwazi ukuphatha imisebenzi yakho yansuku zonke, njengokuphequlula iwebhu kuze kube namathebhu angama-15 we-Chromium, ukuhlela isithombe okulula nge-GIMP nomsebenzi wedokhumenti nowesipredishithi ne-Libre Office.
