Morero oa Raspberry Pi o phatlalalitse ho fumaneha ha moloko o mocha oa boto ea Raspberry Pi Zero W, e kopanyang litekanyo tse kopaneng le tšehetso bakeng sa Bluetooth le Wi-Fi. Mofuta o mocha oa Raspberry Pi Zero 2 W o entsoe ka mokhoa o ts'oanang oa mofuta o monyane (65 x 30 x 5 mm), i.e. hoo e ka bang halofo ea boholo ba Raspberry Pi e tloaelehileng. Thekiso e se e qalile feela UK, European Union, USA, Canada le Hong Kong; lipehelo tse eang linaheng tse ling li tla buloa ha mojule oa mohala o netefatsoa. Litsenyehelo tsa Raspberry Pi Zero 2 W ke $ 15 (ha ho bapisoa, litšenyehelo tsa Raspberry Pi Zero W board ke $ 10, 'me Raspberry Pi Zero ke $ 5; tlhahiso ea liboto tse theko e tlaase e tla tsoela pele).
Phapang ea bohlokoa lipakeng tsa mofuta o mocha oa Raspberry Pi Zero ke phetoho ea ts'ebeliso ea Broadcom BCM2710A1 SoC, haufi le e sebelisitsoeng libotong tsa Raspberry Pi 3 (molokong o fetileng oa liboto tsa Zero, Broadcom BCM2835 SoC e ile ea fanoa, joalo ka Raspberry Pi ea pele). Ho fapana le Raspberry Pi 3, ho fokotsa tšebeliso ea matla, maqhubu a processor a fokotsehile ho tloha 1.4GHz ho ea ho 1GHz. Ha re sheba tlhahlobo ea sysbench e nang le likhoele tse ngata, ntlafatso ea SoC e entse hore ho khonehe ho eketsa ts'ebetso ea boto ka makhetlo a 5 (SoC e ncha e sebelisa quad-core 64-bit Arm Cortex-A53 CPU ho fapana le 32-core 11- hanyane ARM1176 ARMXNUMXJZF-S).
Joalo ka khatisong e fetileng, Raspberry Pi Zero 2 W e fana ka 512MB ea RAM, boema-kepe ba Mini-HDMI, likou tse peli tsa Micro-USB (USB 2.0 e nang le OTG le boema-kepe ba phepelo ea matla), slot ea microSD, sehokelo sa 40-pin GPIO. (ha e rekisoe), Liphetho tse kopaneng tsa video le khamera (CSI-2). Boto e na le chip ea waelese e tšehetsang Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2 le Bluetooth Low Energy (BLE). Ho fetisa setifikeiti sa FCC le ho sireletsa khahlanong le tšitiso ea kantle, chip e se nang mohala ka botong e ncha e koaheloa ka casing ea tšepe.
GPU e kenyellelitsoeng ho SoC e tšehetsa OpenGL ES 1.1 le 2.0, 'me e fana ka lisebelisoa tsa ho potlakisa ho etsa li-video ka liforomo tsa H.264 le MPEG-4 ka boleng ba 1080p30, hammoho le khouto ka sebopeho sa H.264, e leng ho eketsang mefuta e mengata ea tšebeliso ea boto e nang le lisebelisoa tse fapaneng tsa multimedia le litsamaiso tsa lehae le bohlale. Ka bomalimabe, boholo ba RAM bo lekanyelitsoe ho 512 MB mme ha bo khone ho eketsoa ka lebaka la mefokolo ea 'mele ea boholo ba boto. Ho fana ka 1GB ea RAM ho tla hloka ts'ebeliso ea moralo o rarahaneng oa mekhahlelo e mengata, oo bahlahisi ba seng ba itokiselitse ho o sebelisa.
Bothata bo boholo ha ho etsoa boto ea Raspberry Pi Zero 2 W e ne e le ho rarolla taba ea ho beha mohopolo oa LPDDR2 SDRAM. Molokong oa pele oa boto, mohopolo o ne o le mokatong o eketsehileng ka holim'a chip ea SoC, e sebelisitsoeng ho sebelisoa theknoloji ea PoP (package-on-package), empa mokhoa ona o ne o ke ke oa sebelisoa ho li-chips tse ncha tsa Broadcom ka lebaka la keketseho ea boholo ba SoC. Ho rarolla bothata bona, hammoho le Broadcom, ho ile ha etsoa phetolelo e khethehileng ea chip, eo memori e neng e kenyelelitsoe ho SoC.
Bothata bo bong e ne e le ho eketseha ha mocheso oa mocheso ka lebaka la tšebeliso ea processor e matla haholoanyane. Bothata bo ile ba rarolloa ka ho kenyelletsa likarolo tse teteaneng tsa koporo ho boto ho tlosa le ho qhala mocheso ho tloha ho processor. Ka lebaka la sena, boima ba boto bo ile ba eketseha ka mokhoa o hlokomelehang, empa mokhoa ona o ne o nkoa o atlehile mme o ne o lekane ho qoba ho chesa haholo ha o etsa nako e sa lekanyetsoang ea teko ea khatello ea kelello ea algebra ka mocheso o tloaelehileng oa likhato tse 20.
Har'a lisebelisoa tse hlōlisanang, ntho e haufi ka ho fetisisa ho Raspberry Pi Zero 2 W ke boto ea Chaena Orange Pi Zero Plus2, e lekanyang 46x48mm mme e tla ka $ 35 ka 512MB ea RAM le Allwinner H3 chip. Boto ea Orange Pi Zero Plus2 e na le 8 GB EMMC Flash, e na le boema-kepe bo feletseng ba HDMI, slotte ea TF Card, USB OTG, hammoho le mabitso a ho hokahanya microphone, mochine o amohelang mocheso (IR) le likou tse ling tse peli tsa USB. Boto e na le processor ea quad-core Allwinner H5 (Cortex-A53) e nang le Mali Mali450 GPU kapa Allwinner H3 (Cortex-A7) e nang le Mali400MP2 GPU. Sebakeng sa GPIO ea 40-pin, ho fanoa ka sehokelo se khutsufalitsoeng sa 26-pin, se lumellanang le Raspberry Pi B+. Ho boetse ho na le boto ea Orange Pi Zero 2 e seng matla, empa e tla le 1 GB ea RAM le boema-kepe ba Ethernet ho kenyelletsa Wi-Fi.
