Pulojekiti ya Raspberry Pi yalengeza za kupezeka kwa gulu latsopano la Raspberry Pi Zero W board, lomwe limaphatikiza miyeso yaying'ono ndi chithandizo cha Bluetooth ndi Wi-Fi. Mtundu watsopano wa Raspberry Pi Zero 2 W umapangidwa mu mawonekedwe ang'onoang'ono (65 x 30 x 5 mm), i.e. pafupifupi theka la kukula kwa Raspberry Pi wokhazikika. Zogulitsa zangoyamba ku UK, European Union, USA, Canada ndi Hong Kong; zotumizira kumayiko ena zidzatsegulidwa pomwe gawo lopanda zingwe likutsimikiziridwa. Mtengo wa Raspberry Pi Zero 2 W ndi $ 15 (poyerekeza, mtengo wa bolodi la Raspberry Pi Zero W ndi $ 10, ndipo Raspberry Pi Zero ndi $ 5; kupanga matabwa otsika mtengo kudzapitirira).
Kusiyana kwakukulu pakati pa mtundu watsopano wa Raspberry Pi Zero ndikusintha kogwiritsa ntchito Broadcom BCM2710A1 SoC, pafupi ndi yomwe imagwiritsidwa ntchito m'ma board a Raspberry Pi 3 (m'badwo wam'mbuyomu wa Zero board, Broadcom BCM2835 SoC idaperekedwa, monga momwe zilili. woyamba Raspberry Pi). Mosiyana ndi Raspberry Pi 3, kuti muchepetse kugwiritsa ntchito mphamvu, ma processor frequency adachepetsedwa kuchokera ku 1.4GHz kupita ku 1GHz. Kutengera kuyesa kwamitundu yambiri ya sysbench, kusinthidwa kwa SoC kunapangitsa kuti ziwonjezeke kachitidwe ka bolodi nthawi 5 (SoC yatsopano imagwiritsa ntchito quad-core 64-bit Arm Cortex-A53 CPU m'malo mwa single-core 32- pang'ono ARM11 ARM1176JZF-S).
Monga m'kope lapitalo, Raspberry Pi Zero 2 W imapereka 512MB ya RAM, doko la Mini-HDMI, madoko awiri a Micro-USB (USB 2.0 yokhala ndi OTG ndi doko lamagetsi), kagawo kakang'ono ka microSD, cholumikizira cha 40-pin GPIO. (osagulitsidwa), Makanema ophatikizika ndi makamera (CSI-2). Bungweli lili ndi chip opanda zingwe chomwe chimathandizira Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2 ndi Bluetooth Low Energy (BLE). Kuti mudutse chiphaso cha FCC ndikuteteza ku kusokonezedwa kwakunja, chip opanda zingwe mu bolodi yatsopano chimakutidwa ndi chitsulo.
GPU yophatikizidwa mu SoC imathandizira OpenGL ES 1.1 ndi 2.0, ndipo imapereka zida zofulumizitsa kutsitsa makanema mu H.264 ndi MPEG-4 mawonekedwe okhala ndi 1080p30, komanso encoding mu mtundu wa H.264, womwe umakulitsa kuchuluka kwa kugwiritsa ntchito bolodi yokhala ndi zida zosiyanasiyana zama multimedia ndi machitidwe a nyumba yanzeru. Tsoka ilo, kukula kwa RAM kumangokhala 512 MB ndipo sikungawonjezeke chifukwa cha kuchepa kwa bolodi. Kupereka 1GB ya RAM kungafune kugwiritsa ntchito mapangidwe ovuta amitundu yambiri, omwe opanga sanafikebe okonzeka kuyigwiritsa.
Vuto lalikulu popanga bolodi la Raspberry Pi Zero 2 W linali kuthetsa vuto loyika kukumbukira kwa LPDDR2 SDRAM. M'badwo woyamba wa bolodi, kukumbukira kunali m'malo owonjezera pamwamba pa chipangizo cha SoC, chogwiritsidwa ntchito pogwiritsa ntchito teknoloji ya PoP (package-pa-package), koma njirayi sinathe kukhazikitsidwa muzitsulo zatsopano za Broadcom chifukwa cha kuwonjezeka kwa kukula kwa SoC. Kuti athetse vutoli, pamodzi ndi Broadcom, mtundu wapadera wa chip unapangidwa, momwe kukumbukira kunaphatikizidwa mu SoC.
Vuto lina linali kuwonjezeka kwa kutentha kwa kutentha chifukwa cha kugwiritsa ntchito purosesa yamphamvu kwambiri. Vutoli linathetsedwa powonjezera zigawo za mkuwa wandiweyani pa bolodi kuti muchotse ndi kutaya kutentha kwa purosesa. Chifukwa cha izi, kulemera kwa bolodi kunakula kwambiri, koma njirayo inkaonedwa kuti ndi yopambana ndipo inali yokwanira kupewa kutenthedwa pamene mukuchita nthawi yopanda malire LINPACK mayeso a maganizo a algebra pa kutentha kozungulira kwa madigiri 20.
Pazida zopikisana, chomwe chili pafupi kwambiri ndi Raspberry Pi Zero 2 W ndi bolodi yaku China Orange Pi Zero Plus2, yomwe imayesa 46x48mm ndipo imabwera ndi $ 35 ndi 512MB ya RAM ndi Chip Allwinner H3. Bolodi la Orange Pi Zero Plus2 lili ndi 8 GB EMMC Flash, ili ndi doko lathunthu la HDMI, kagawo ka TF Card, USB OTG, komanso mauthenga olumikizira maikolofoni, cholandirira cha infrared (IR) ndi madoko awiri owonjezera a USB. Gululi lili ndi purosesa ya quad-core Allwinner H5 (Cortex-A53) yokhala ndi Mali Mali450 GPU kapena Allwinner H3 (Cortex-A7) yokhala ndi Mali400MP2 GPU. M'malo mwa GPIO ya pini 40, cholumikizira chachifupi cha 26-pini chimaperekedwa, chogwirizana ndi Raspberry Pi B+. Gulu la Orange Pi Zero 2 lamphamvu kwambiri likupezekanso, koma limabwera ndi 1 GB ya RAM ndi doko la Ethernet kuwonjezera pa Wi-Fi.
