Eben Upton, aasaasaha Raspberry Pi ayaa daaha laga qaaday dhawaan cusub Raspberry Pi Zero 2W Waxay la socotaa processor-ka 1GHZ kaas oo, marka loo eego soo-saaraha, bixiya 5 jeer wax qabad badan oo loogu talagalay culeysyada shaqada ee badan ee 2015 Raspberry Pi Zero.
Raspberry Pi Zero 2W-ka cusub wuxuu kaloo keenayaa koofiyadaha gacanta oo xoogaa hoos u dhacay ilaa 1GHz, 512MB ee LPDDR2 SDRAM oo lagu xiray hal golaha meel-badbaadinta $15.
Kuwa aan aqoon u lahayn Raspberry Pi, fadlan ogow in kani yahay kombuyuutar guddi keliya oo ARM ah oo kaadhka deynta ah oo ay naqshadeeyeen macalimiin ka socda waaxda Sayniska Kombiyuutarka ee Jaamacadda Cambridge oo qayb ka ah Raspberry Pi Foundation.
Waxaa loo abuuray in lagu dimoqraadiyeeyo gelitaanka kombiyuutarada iyo abuurista dhijitaalka ah. Raspberry Pi wuxuu u oggolaanayaa fulinta dhowr nooc oo ah nidaamka hawlgalka GNU / Linux ee bilaashka ah, gaar ahaan Debian, iyo softiweer ku habboon.
Ku saabsan Raspberry Pi Zero 2W cusub
Waxaa lagu qiimeeyay $15, Raspberry Pi Zero 2W waxay isticmaashaa isla Broadcom BCM2710A1 SoC chip Marka loo eego nooca la sii daayo ee Raspberry Pi 3. Kordhinta waxqabadka saxda ah ee eberku way ku kala duwan tahay culeysyada shaqada, laakiin sysbench-ka badan ee dunta leh, waxay ku dhowdahay sida saxda ah shan jeer.
Ku saabsan astaamaha Raspberry Pi Zero 2W waa sida soo socota:
- Mini HDMI dekedda
- 512MB LPDDR2 SDRAM
- CSI-2 isku xiraha kamarada
- 1 × USB 2.0 interface oo leh OTG
- Garaafyada OpenGL ES 1.1, 2.0
- 40-pin koofiyada u hoggaansan I / O
- Afyare kaadhka MicroSD
- 2,4 GHz WiFi 802.11 b / g / n, Bluetooth 4.2, BLE
- H.264, MPEG-4 (1080p30) dejinta; H.264 (1080p30) codaynta
- Broadcom BCM2710A1, 64-bit Quad Core SoC (53 GHz Arm Cortex-A1)
- Dhibcaha alxanka fiidiyooga oo isku dhafan oo dib u deji pin
Injineerka Raspberry Pi Simon Martin, oo naqshadeeyay Zero 2W iyo sanduuqa RP3A0 ee awood u leh, ayaa ku guulaystay inuu ku tuujiyo dhammaan waxqabadkaas dheeraadka ah ee qaabka asalka ah ee Zero.
Caqabadda ugu weyn ee abuuritaanka Raspberry Pi Zero oo karti badan ayaa had iyo jeer ahayd qodobka- Iyada oo loox yar iyo meelaynta ka kooban hal dhinac ah, ma jirto meel bannaan oo jirka ah si ay u dejiyaan labada nidaamka muhiimka ah ee chip (SoC) iyo SDRAM discrete.
Sida Raspberry Pi 1, Raspberry Pi Zero iyo Zero W waxay ku saleysan yihiin Broadcom BCM2835 SoC. Midda dambe waxay ka fogaataa dhibaatada iyadoo la isticmaalayo tignoolajiyada PoP (baakidh ka badan baakidh), kaas oo sanduuqa SDRAM uu si toos ah uga sarreeyo SoC-ga.
PoP waa xal xarrago leh haddii qalabka silikoonka ee SoC uu yar yahay oo ku habboon daloolka u dhexeeya kiiska ugu sarreeya ee SDRAM. Nasiib darro, markii Broadcom ay ku dartay Quad Cortex-A7 (si loo abuuro BCM2836), ka dibna Quad Cortex-A53 (si loo abuuro BCM2837), chip wuxuu dhex maray godka PoP.
Kuleylku waa caqabad marka wax qabad badan lagu xirayo xirmo yar - sidee buu u firdhiyaa kulaylka uu dhaliyo processor-ka degdega ah? Sida alaabada kale ee Raspberry Pi ee dhawaanahan, Zero 2W waxay isticmaashaa lakabyo naxaas ah oo qaro weyn si ay uga saarto kulaylka processor-ka. Haddii aad gacmahaaga ku haysato eber W iyo eber 2 W, waxaad runtii dareemi kartaa farqiga miisaanka.
Ilaa hadda, iibku wuxuu ka bilaabmay UK, Midowga Yurub, US, Canada iyo Hong Kong; Gaadhida wadamada kale waxa la furi doonaa marka moduleka bilaa-waayirka la shahaado. Qiimaha Raspberry Pi Zero 2 W waa $ 15 (marka la barbardhigo, qiimaha guddiga Raspberry Pi Zero W waa $ 10 iyo Raspberry Pi Zero waa $ 5, soosaarka looxyada jaban ayaa sii socon doona).
Haddii aad xiisaynayso inaad wax badan ka ogaato, waad hubin kartaa faahfaahinta xiriirka soo socda.
Ugu dambeyntii, tWaxa kale oo ay mudan tahay in la muujiyo horumarka Raspberry Pi sidoo kale lagu dhawaaqay una Awood cusub oo USB ah oo rasmi ah oo la socota Zero 2 W.
Waxay u egtahay wax badan sida Raspberry Pi 4, laakiin leh xiriiriyaha micro-B ee USB halkii xiriiriyaha USB. C, iyo iyadoo hadda ugu sarreysa wax yar laga dhigay 2.5A. Aad bay faa'iido u leedahay haddii aad rabto inaad awood u yeelato Raspberry Pi 3B ama 3B +.
Korontada waxaa lagu heli karaa noocyada soo socda ee furayaasha: Mareykanka iyo Kanada (nooca A); Yurub (nooca C); Hindiya (nooca D); Boqortooyada Ingiriiska (nooca G); iyo Australia, New Zealand iyo Shiinaha (nooca I).
