U-Eben Upton, umsunguli we-Raspberry Pi wembulwe muva okusha I-Raspberry Pi Zero 2W Iza nephrosesa engu-1GHZ okuthi, ngokomkhiqizi, inikeze ukusebenza okuphindwe ka-5 komthwalo owenziwe ngethreaded eminingi kune-Raspberry Pi Zero ka-2015.
I-Raspberry Pi Zero 2W entsha futhi iletha ama-Arm cores ehliswe kancane ukuya ku-1GHz, i-512MB ye-LPDDR2 SDRAM ehlanganiswe kwikhabhinethi eyodwa yokonga isikhala ngama- $ 15.
Kulabo abangayazi i-Raspberry Pi, sicela wazi ukuthi lena ikhompyutha yebhodi yephrosesa ye-ARM elingana nekhadi lesikweletu eklanywe ngosolwazi bomnyango we-Computer Science eNyuvesi yaseCambridge njengengxenye ye-Raspberry Pi Foundation.
Yakhelwe ukwenza intando yeningi amakhompuyutha okufinyelela nokudalwa kwedijithali. I-Raspberry Pi ivumela ukukhishwa kwezinhlobonhlobo eziningana zesistimu yokusebenza yamahhala ye-GNU / Linux, ikakhulukazi i-Debian, nesofthiwe ehambisanayo.
Mayelana ne-Raspberry Pi Zero 2W entsha
Intengo ka-$15, i-Raspberry Pi Zero 2W isebenzisa i-chip efanayo ye-Broadcom BCM2710A1 SoC kunenguqulo yokukhishwa ye-Raspberry Pi 3. Ukwenyuka okuqondile kokusebenza ngaphezu kwe-Zero kuyahlukahluka ngomthwalo wokusebenza, kodwa ku-sysbench enezintambo eziningi, ishesha cishe ngokuphindwe kahlanu.
Mayelana nezici ye-Raspberry Pi Zero 2W imi kanje:
- Imbobo encane ye-HDMI
- 512MB LPDDR2 SDRAM
- Isixhumi sekhamera ye-CSI-2
- 1 × isixhumi esibonakalayo se-USB 2.0 esine-OTG
- Imidwebo ye-OpenGL ES 1.1, 2.0
- I-HAT yamaphini angu-40 ithobela i-I / O
- Ikhadi le-MicroSD slot
- 2,4 GHz WiFi 802.11 b / g / n, Bluetooth 4.2, BLE
- H.264, MPEG-4 (1080p30) ukubhala ikhodi; H.264 (1080p30) umbhalo wekhodi
- I-Broadcom BCM2710A1, 64-bit Quad Core SoC (53 GHz Arm Cortex-A1)
- Amaphoyinti e-solder wevidiyo eyinhlanganisela nephinikhodi yokusetha kabusha.
Unjiniyela we-Raspberry Pi u-Simon Martin, owaklama i-Zero 2W kanye nebhokisi le-RP3A0 elinika amandla, ukwazile ukuminyanisa konke lokho kusebenza okwengeziwe ku-Zero form factor yasekuqaleni.
Isithiyo esikhulu sokudala i-Raspberry Pi Zero enekhono kakhulu bekulokhu kuyisici sefomu- Ngebhodi elincane kanye nokubekwa kwengxenye yohlangothi olulodwa, asikho isikhala esiphathekayo sokufaka kokubili uhlelo oluyinhloko ku-chip (SoC) kanye ne-SDRAM ehlukile.
Njenge-Raspberry Pi 1, i-Raspberry Pi Zero ne-Zero W zisekelwe ku-Broadcom BCM2835 SoC. Lesi sakamuva sigwema inkinga ngokusebenzisa ubuchwepheshe be-PoP (iphakethe phezu kwephakethe), lapho ibhokisi le-SDRAM lihlala khona ngqo ngaphezu kwe-SoC.
I-PoP iyisixazululo esihle uma i-silicon chip ye-SoC incane ngokwanele ukuthi ingangena emgodini phakathi kwekesi eliphezulu le-SDRAM. Ngeshwa, lapho i-Broadcom ingeza i-Quad Cortex-A7 (ukwakha i-BCM2836), kwase kuba i-Quad Cortex-A53 (ukwakha i-BCM2837), i-chip yadlula emgodini we-PoP.
I-Thermal iyinselele uma upakisha ukusebenza okwengeziwe kuphakheji elincane - ukushisa okukhiqizwa iphrosesa esheshayo kushabalaliswa kanjani? Njengeminye imikhiqizo yakamuva ye-Raspberry Pi, i-Zero 2W isebenzisa izendlalelo zethusi zangaphakathi eziwugqinsi ukuze isuse ukushisa kuphrosesa. Uma unoziro W kanye noZiro 2 W ezandleni zakho, ungawuzwa ngempela umehluko ngesisindo.
Kuze kube manje, ukuthengisa kuqale kuphela e-UK, e-European Union, e-US, eCanada naseHong Kong; Ukulethwa kwamanye amazwe kuzovulwa uma imojula engenantambo isiqinisekisiwe. Izindleko zeRaspberry Pi Zero 2 W zingama- $ 15 (uma kuqhathaniswa, izindleko zebhodi le-Raspberry Pi Zero W zingama- $ 10 kanti i-Raspberry Pi Zero ingu-$ 5, ukukhiqizwa kwamabhodi ashibhile kuzoqhubeka) .
Uma ungathanda ukwazi okwengeziwe ngayo, ungabheka ifayela le- imininingwane kusixhumanisi esilandelayo.
Ekugcineni, tKuyafaneleka futhi ukugqamisa ukuthuthukiswa kwe-Raspberry Pi kumenyezelwe una ugesi omusha osemthethweni we-USB ozohambisana ne-Zero 2 W.
Kubukeka kufana kakhulu nogesi we-Raspberry Pi 4, kodwa ngesixhumi se-USB micro-B esikhundleni sesixhumi se-USB. C, futhi nenani eliphakeme lehliswe kancane libe ngu-2.5A. Iwusizo kakhulu uma ufuna ukunika amandla i-Raspberry Pi 3B noma i-3B +.
Ukunikezwa kwamandla kuyatholakala ngezinhlobo ezilandelayo zamapulaki: I-United States ne-Canada (uhlobo A); IYurophu (uhlobo C); I-India (uhlobo D); I-United Kingdom (uhlobo G); kanye ne-Australia, i-New Zealand ne-China (uhlobo I).
