Mashruuca Raspberry Pi wuxuu ku dhawaaqay helitaanka jiil cusub oo ah guddiga Raspberry Pi Zero W, kaas oo isku daraya cabbirro is haysta oo taageero u ah Bluetooth iyo Wi-Fi. Qaabka cusub ee Raspberry Pi Zero 2 W waxa lagu sameeyay qaab isku mid ah oo yar (65 x 30 x 5 mm), i.e. qiyaastii kala badh cabbirka Raspberry Pi caadiga ah. Iibka ayaa ilaa hadda ka bilaabmay UK, Midowga Yurub, USA, Canada iyo Hong Kong; keenista wadamada kale waxa ay furmi doontaa sida module-ka bilaa-waayirka ah la shahaado. Qiimaha Raspberry Pi Zero 2 W waa $15 (marka la barbardhigo, qiimaha guddiga Raspberry Pi Zero W waa $10, Raspberry Pi Zero waa $5; soo saarista looxyada jaban ayaa sii socon doona).
Farqiga ugu muhiimsan ee u dhexeeya nooca cusub ee Raspberry Pi Zero waa u-guurka isticmaalka Broadcom BCM2710A1 SoC, oo u dhow kii loo adeegsaday looxyada Raspberry Pi 3 (jiilkii hore ee looxyada Zero, Broadcom BCM2835 SoC ayaa la keenay, sida in Raspberry Pi ugu horeysay). Si ka duwan Raspberry Pi 3, si loo yareeyo isticmaalka tamarta, soo noqnoqda processor-ka ayaa laga soo yareeyay 1.4GHz ilaa 1GHz. Marka la eego tijaabada sysbench-ka badan ee dunta leh, cusboonaysiinta SoC waxay suurtagelisay in la kordhiyo waxqabadka guddiga 5 jeer (SoC-da cusub waxay isticmaashaa quad-core 64-bit Arm Cortex-A53 CPU halkii ay ka ahaan lahayd hal-core 32- xoogaa ARM11 ARM1176JZF-S).
Sida daabacadii hore, Raspberry Pi Zero 2 W wuxuu bixiyaa 512MB RAM, deked Mini-HDMI, laba dekedood oo Micro-USB ah (USB 2.0 oo leh OTG iyo deked koronto), booska microSD, isku xirka GPIO 40-pin (aan la iibin), Fiidiyowga isku dhafan iyo wax soo saarka kamarada (CSI-2). Guddidu waxa ay ku qalabaysan tahay chip wireless oo taageera Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2 iyo Bluetooth Low Energy (BLE). Si aad uga gudubto shahaadada FCC oo aad uga ilaaliso faragelinta dibadda, chip-ka wireless-ka ee guddiga cusub waxaa lagu daboolay dabool bir ah.
GPU-da oo lagu daray SoC-da waxay taageertaa OpenGL ES 1.1 iyo 2.0, waxayna siisaa qalab loogu talagalay dardargelinta dejinta fiidiyoowga ee H.264 iyo MPEG-4 oo leh 1080p30 oo tayo leh, iyo sidoo kale qaabka H.264, kaas oo ballaarinaya baaxadda isticmaalka looxa oo leh aalado kala duwan oo kala duwan iyo nidaamyada loogu talagalay guri caqli badan. Nasiib darro, cabbirka RAM wuxuu ku xaddidan yahay 512 MB lama kordhin karo sababtoo ah xaddidnaanta jirka ee cabbirka guddiga. Si loo bixiyo 1GB ee RAM waxay u baahan doontaa isticmaalka nashqada lakabyo badan oo kakan, kaas oo horumariyayaashu aanay wali diyaar u ahayn inay hirgeliyaan.
Dhibaatada ugu weyn marka la naqshadeynayo guddiga Raspberry Pi Zero 2 W waxay xallinaysay arrinta meelaynta LPDDR2 SDRAM xusuusta. Jiilkii ugu horreeyay ee guddiga, xusuusta waxay ku taallaa lakab dheeri ah oo ka sarreeya Chip SoC, oo lagu hirgeliyay tignoolajiyada PoP (package-on-package), laakiin farsamadan laguma hirgelin karo chips-yada cusub ee Broadcom sababtoo ah kororka cabbirka SoC. Si loo xalliyo dhibaatadan, oo ay weheliso Broadcom, nooc gaar ah oo chip-ka ayaa la sameeyay, kaas oo xusuusta lagu dhex daray SoC.
Dhibaato kale ayaa ahayd kororka kuleylka kuleylka sababtoo ah isticmaalka processor awood badan. Dhibaatada waxaa lagu xalliyay iyada oo lagu daray lakabyo naxaas ah oo qaro weyn oo looxa ah si looga saaro oo looga saaro kuleylka processor-ka. Sababtan awgeed, miisaanka looxa si muuqata ayuu u kordhay, laakiin farsamada ayaa loo tixgeliyey inay guulaysatay oo waxay ku filnayd in laga fogaado kulaylka marka la samaynayo wakhti aan xadidnayn LINPACK tijaabada cadaadiska aljebrada toosan ee heerkulka deegaanka ee 20 digrii.
Qalabka tartanka ku jira, waxa ugu dhow Raspberry Pi Zero 2 W waa guddiga Shiinaha Orange Pi Zero Plus2, kaas oo cabbiraya 46x48mm wuxuuna ku yimaadaa $35 oo leh 512MB ee RAM iyo Allwinner H3 chip. Boodhka Orange Pi Zero Plus2 wuxuu ku qalabaysan yahay 8 GB EMMC Flash, wuxuu leeyahay deked HDMI oo buuxa, booska TF Card, USB OTG, iyo sidoo kale xiriirada isku xirka makarafoonka, qaataha infrared (IR) iyo laba dekedood oo USB oo dheeri ah. Guddidu waxay ku qalabaysan tahay processor-ka Quad-core Allwinner H5 (Cortex-A53) oo leh Mali Mali450 GPU ama Allwinner H3 (Cortex-A7) oo leh Mali400MP2 GPU. Halkii laga heli lahaa 40-pin GPIO, xiriiriye 26-pin ah oo la gaabiyay ayaa la keenay, oo ku habboon Raspberry Pi B+. Boodhka Orange Pi Zero 2 oo ka awood yar ayaa sidoo kale la heli karaa, laakiin wuxuu la imaanayaa 1 GB oo RAM ah iyo deked Ethernet ah marka lagu daro Wi-Fi.
