Aikin Raspberry Pi ya ba da sanarwar samuwan tsararraki na gaba na Rasberi Pi Zero W, wanda ya haɗu da ƙaramin girman tare da tallafin Bluetooth da Wi-Fi. Sabuwar samfurin Rasberi Pi Zero 2 W an yi shi a cikin ƙaramin nau'i iri ɗaya (65 x 30 x 5 mm), watau. kusan rabin girman Rasberi Pi na yau da kullun. Ya zuwa yanzu, an fara tallace-tallace ne kawai a cikin Burtaniya, Tarayyar Turai, Amurka, Kanada da Hong Kong, jigilar kayayyaki zuwa wasu ƙasashe za su buɗe yayin da tsarin mara waya ya wuce takaddun shaida. Rasberi Pi Zero 2 W ana saka farashi akan $15 (don kwatantawa, Rasberi Pi Zero W shine $10 kuma Rasberi Pi Zero shine $5, za a ci gaba da yin alluna masu rahusa).
Babban bambancin sabon samfurin Rasberi Pi Zero shine canji zuwa amfani da Broadcom BCM2710A1 SoC, kusa da wanda aka yi amfani da shi a cikin allunan Rasberi Pi 3 (a cikin ƙarni na baya na allon Zero, an ba da Broadcom BCM2835 SoC, kamar yadda a cikin Rasberi Pi na farko). Ba kamar Rasberi Pi 3 ba, an rage mitar processor daga 1.4GHz zuwa 1GHz don rage amfani da wutar lantarki. Yin la'akari da gwajin sysbench da yawa, sabuntawar SoC ya ba da damar haɓaka aikin hukumar ta sau 5 (sabon SoC yana amfani da quad-core 64-bit Arm Cortex-A53 CPU maimakon guda-core 32-bit ARM11. ARM1176JZF-S).
Kamar yadda yake a cikin fitowar da ta gabata, Rasberi Pi Zero 2 W yana ba da 512MB na RAM, tashar Mini-HDMI, tashar USB Micro-USB guda biyu (USB 2.0 tare da OTG da tashar jiragen ruwa don samar da wutar lantarki), ramin microSD, GPIO mai 40-pin. kan kai (ba a sayar da shi ba), abubuwan da aka fitar don hada bidiyo da kamara (CSI-2). An sanye da allo da guntu mara waya wanda ke goyan bayan Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2, da Bluetooth Low Energy (BLE). Don ƙetare takaddun shaida na FCC da kariya daga tsangwama na waje, guntu mara igiyar waya a cikin sabon allo an rufe shi da murfi na ƙarfe.

Abin takaici, girman RAM yana iyakance zuwa 512 MB kuma ba za a iya ƙarawa ba saboda iyakokin jiki na girman allo. Isar da 1GB na RAM zai buƙaci amfani da ƙira mai sarƙaƙƙiya da yawa, wanda masu haɓakawa ba su shirya aiwatarwa ba tukuna.
Babban ƙalubalen ƙira don kwamitin Rasberi Pi Zero 2 W shine sanya LPDDR2 SDRAM. A cikin ƙarni na farko na allon, an sanya ƙwaƙwalwar ajiya a cikin ƙarin Layer sama da guntu na SoC, wanda aka aiwatar ta hanyar amfani da fasahar PoP (kunshi-on-package), amma ba za a iya aiwatar da wannan dabarar a cikin sabbin kwakwalwan kwamfuta na Broadcom ba saboda karuwar a cikin. girman SoC. Don magance wannan matsala, tare da Broadcom, an ƙirƙiri sigar guntu na musamman, wanda aka haɗa ƙwaƙwalwar ajiya a cikin SoC.
Wata matsala kuma ita ce karuwar zafi saboda amfani da na'ura mai mahimmanci. An magance matsalar ta hanyar ƙara yadudduka masu kauri a kan allo don cirewa da zubar da zafi daga na'urar.

Daga cikin na'urorin da ke fafatawa, abin da ya fi kusa da Rasberi Pi Zero 2 W shine Orange Pi Zero Plus2 na kasar Sin, wanda ke auna 46x48mm kuma yana jigilar kaya akan $35 tare da 512MB na RAM da guntu Allwinner H3. The Orange Pi Zero Plus2 allon sanye take da 8 GB EMMC Flash, yana da cikakken tashar tashar HDMI, Ramin TF Card, USB OTG, da kuma fil don haɗa makirufo, mai karɓar infrared (IR) da ƙarin tashoshin USB guda biyu. Jirgin yana sanye da na'ura mai sarrafa Quad-core Allwinner H5 (Cortex-A53) tare da Mali Mali450 GPU ko Allwinner H3 (Cortex-A7) tare da Mali400MP2 GPU. Maimakon GPIO mai 40-pin, akwai raƙuman kai mai 26-pin wanda ya dace da Rasberi Pi B+. Hakanan ana samun ƙaramin allo Orange Pi Zero 2, amma yana zuwa tare da 1 GB na RAM da tashar Ethernet ban da Wi-Fi.
