Klju\u010dna razlika nove razli\u010dice Raspberry Pi Zero je prehod na uporabo SoC Broadcom BCM2710A1, ki je podoben tistemu, ki se uporablja v plo\u0161\u010dah Raspberry Pi 3 (v prej\u0161nji generaciji plo\u0161\u010d Zero se je uporabljal SoC Broadcom BCM2835, kot v prvem Raspberry Pi). V nasprotju z Raspberry Pi 3 je bila za zmanj\u0161anje porabe energije frekvenca procesorja zni\u017eana z 1,4 GHz na 1 GHz. Sode\u010d po ve\u010dpredstavni\u010dni testi sysbench je nadgradnja SoC omogo\u010dila petkratno pove\u010danje zmogljivosti plo\u0161\u010de (v novem SoC se uporablja \u0161tirijedrni 64-bitni CPU Arm Cortex-A53 namesto enojedrnega 32-bitnega ARM11 ARM1176JZF-S). <\/p>\n

Kot v prej\u0161nji razli\u010dici ponuja Raspberry Pi Zero 2 W 512 MB RAM-a, priklju\u010dek Mini-HDMI, dva priklju\u010dka Micro-USB (USB 2.0 z OTG in priklju\u010dek za napajanje), slot microSD, 40-pinski GPIO priklju\u010dek (ni spajkan), izhode za kompozitni video in kamero (CSI-2). Plo\u0161\u010da je opremljena z brez\u017ei\u010dnim \u010dipom, ki podpira Wi-Fi 802.11 b\/g\/n (2,4 GHz), Bluetooth 4.2 in Bluetooth Low Energy (BLE). Za pridobitev certifikata FCC in za\u0161\u010dito pred zunanjimi motnjami je brez\u017ei\u010dni \u010dip v novi plo\u0161\u010di za\u0161\u010diten z kovinskim ohi\u0161jem. <\/p>\n

Integrirani GPU v SoC podpira OpenGL ES 1.1 in 2.0 ter nudi sredstva za pospe\u0161evanje dekodiranja videa v formatih H.264 in MPEG-4 z kakovostjo 1080p30, ter kodiranja v formatu H.264, kar \u0161iri podro\u010dje uporabe plo\u0161\u010de v razli\u010dnih multimedijskih napravah in sistemih za pametne domove. Na \u017ealost je koli\u010dina RAM-a omejena na 512 MB in je ne moremo pove\u010dati zaradi fizi\u010dnih omejitev velikosti plo\u0161\u010de. Za dobavo 1 GB RAM-a bi bilo potrebno uporabiti zahtevnej\u0161o ve\u010dplastno konstrukcijo, ki je zaenkrat \u0161e ni mogo\u010de implementirati.

Glavna te\u017eava pri oblikovanju plo\u0161\u010de Raspberry Pi Zero 2 W je bila re\u0161itev vpra\u0161anja postavitve pomnilnika LPDDR2 SDRAM. V prvi generaciji plo\u0161\u010de je bil pomnilnik name\u0161\u010den v dodatnem sloju nad \u010dipom SoC, izveden z uporabo tehnologije PoP (package-on-package), vendar v novih \u010dipih Broadcom tak\u0161ne re\u0161itve ni bilo mogo\u010de uvesti zaradi pove\u010danja velikosti SoC. Za re\u0161itev te te\u017eave je bilo skupaj s podjetjem Broadcom razvito posebno razli\u010dico \u010dipa, v katerem je bil pomnilnik integriran v SoC.

\u0160e en izziv je predstavljalo pove\u010dano toplotno oddajanje zaradi uporabe mo\u010dnej\u0161ega procesorja. Problem je bil re\u0161en z dodajanjem debelih bakrovih slojev na plo\u0161\u010do za odvod in razpr\u0161evanje toplote od procesorja. Te\u017ea plo\u0161\u010de se je zaradi tega znatno pove\u010dala, vendar se je re\u0161itev izkazala za uspe\u0161no in bila je dovolj, da se prepre\u010di pregrevanje med neskon\u010dno dolgim stres testom linearne algebra LINPACK pri okoljski temperaturi 20 stopinj. <\/p>\n
