I-Raspberry Pi Zero 2W ifika kunye namaxesha angama-5 ngaphezulu kwamandla kunye ne-15 yeedola kuphela

Eben Upton, umseki weRaspberry Pi watyhilwa kutshanje entsha iRaspberry Pi Zero 2W Iza kunye neprosesa ye-1GHZ ethi, ngokutsho komenzi, inikezela ngokuphindwe ka-5 ukusebenza okungaphezulu kwemisebenzi emininzi kune-Raspberry Pi Zero esuka kwi-2015.

I-Raspberry Pi Zero 2W entsha izisa ii-Arm cores zithotywe kancinci ukuya kwi-1GHz, i-512MB ye-LPDDR2 SDRAM edityaniswe kwikhabhathi enye yokugcina indawo ye-15 yeedola.

Kwabo bangayazi iRaspberry Pi, nceda wazi ukuba le yikhadi letyala le-ARM yeprosesa yebhodi enye yekhompyuter eyenzelwe oonjingalwazi beSebe leSayensi yeKhompyutha kwiYunivesithi yaseCambridge njengenxalenye yeRaspberry Pi Foundation.

Yenzelwe ukwenza idemokhrasi ukufikelela kwiikhompyuter kunye nokudalwa kwedijithali. IRaspberry Pi ivumela ukwenziwa kwezinto ezininzi ezahlukeneyo zenkqubo yokusebenza ye-GNU / Linux, ngakumbi iDebian, kunye nesoftware ehambelanayo.

Malunga neRaspberry Pi Zero 2W entsha

Ixabiso nge-15 yeedola, iRaspberry Pi Zero 2W isebenzisa i-chip efanayo ye-Broadcom BCM2710A1 SoC kunokukhululwa kwenguqulo ye-Raspberry Pi 3. Ukunyuka kwentsebenzo ngokuthe ngqo kwi-Zero kuyahluka kunye nomthwalo wemisebenzi, kodwa kwi-sysbench enemisonto emininzi, iphantse ibe ngokuchanekileyo ngokuphindwe kahlanu ngokukhawuleza.

Malunga neempawu yeRaspberry Pi Zero 2W zezi zilandelayo:

  • Mini HDMI port
  • I-512 MB LPDDR2 SDRAM
  • CSI-2 isinxibelelanisi sekhamera
  • 1 × USB 2.0 ujongano kunye OTG
  • Imizobo ye-OpenGL ES 1.1, 2.0
  • I-40-pin HAT iyahambelana ne-I / O
  • Ikhadi le-MicroSD slot
  • 2,4 GHz WiFi 802.11 b / g / n, Bluetooth 4.2, BLE
  • H.264, MPEG-4 (1080p30) ukubhalwa kwekhowudi; H.264 (1080p30) ukufakwa kweekhowudi
  • Broadcom BCM2710A1, 64-bit Quad Core SoC (53 GHz Arm Cortex-A1)
  • Amanqaku e-solder yevidiyo ehlanganisiweyo kunye nephini lokuseta kwakhona.

Injineli yeRaspberry Pi uSimon Martin, owayila i-Zero 2W kunye nebhokisi ye-RP3A0 eyinika amandla, ukwazile ukucudisa yonke loo ntsebenzo eyongezelelweyo kwifom ye-Zero yokuqala.

Umqobo ophambili wokwenza iRaspberry Pi Zero ekwaziyo ngakumbi ibisoloko iyifom factor- Ngebhodi encinci kunye nokubekwa kwecandelo elinye, akukho ndawo ebonakalayo yokuhlalisa zombini inkqubo ephambili kwi-chip (SoC) kunye ne-SDRAM ecacileyo.

NjengeRaspberry Pi 1, iRaspberry Pi Zero kunye neZero W zisekelwe kwi-Broadcom BCM2835 SoC. Lo mva unqanda ingxaki ngokusebenzisa i-PoP (ipakethi phezu kwepakethi) iteknoloji, apho ibhokisi ye-SDRAM ihleli ngqo phezu kwe-SoC.

I-PoP sisisombululo esihle ukuba i-silicon chip kwi-SoC incinci ngokwaneleyo ukuba ingene kumgodi phakathi kwetyala eliphezulu le-SDRAM. Ngelishwa, xa i-Broadcom yongeza i-Quad Cortex-A7 (ukwenza i-BCM2836), emva koko i-Quad Cortex-A53 (ukwenza i-BCM2837), i-chip yadlula kwi-PoP cavity.

I-Thermal ingumceli mngeni xa upakisha ukusebenza okungaphezulu kwipakethe encinci - bunjani ubushushu obuveliswa yiprosesa ekhawulezayo yokuchithwa? Njengezinye iimveliso zeRaspberry Pi zamva nje, iZero 2W isebenzisa umaleko ongqindilili wobhedu wangaphakathi ukususa ubushushu kwiprosesa. Ukuba unoZero W kunye no-Zero 2 W ezandleni zakho, unokuwuva ngokwenene umahluko kubunzima.

Ukuza kuthi ga ngoku, ukuthengisa kuqale kuphela e-UK, kwi-European Union, e-US, eCanada naseHong Kong; ukuhanjiswa kwamanye amazwe kuya kuvulwa xa imodyuli engenazingcingo iqinisekisiwe. Iindleko zeRaspberry Pi Zero 2 W yi-$ 15 (ngokuthelekisa, iindleko zebhodi yeRaspberry Pi Zero W yi-$ 10 kunye neRaspberry Pi Zero yi-$ 5, ukuveliswa kweebhodi ezishibhile kuya kuqhubeka) .

Ukuba unomdla wokwazi ngakumbi ngayo, ungajonga iifayile ze- iinkcukacha kwikhonkco elilandelayo.

Okokugqibela, tKukwafanelekile ukugqamisa uphuhliso lweRaspberry Pi nayo yabhengezwa unayo unikezelo lwamandla olutsha lwe-USB olusemthethweni ukuba lukhaphe u-Zero 2 W.

Ijongeka kakhulu njengombane weRaspberry Pi 4, kodwa nge-USB micro-B isinxibelelanisi endaweni yesinxibelelanisi se-USB. C, kunye nencopho yangoku ithotywe kancinane ukuya kwi-2.5A. Iluncedo kakhulu ukuba ufuna ukunika amandla iRaspberry Pi 3B okanye 3B +.

Ukunikezelwa kombane kufumaneka ngeentlobo ezilandelayo zeeplagi: i-United States kunye neKhanada (uhlobo A); IYurophu (uhlobo C); I-Indiya (uhlobo D); eUnited Kingdom (uhlobo G); kunye neOstreliya, iNew Zealand neTshayina (uhlobo I).
