Iyo Raspberry Pi purojekiti yakazivisa kuwanikwa kwechizvarwa chitsva cheRaspberry Pi Zero W bhodhi, iyo inosanganisa compact zviyero nerutsigiro rweBluetooth neWi-Fi. Iyo itsva Raspberry Pi Zero 2 W modhi inogadzirwa mune imwechete miniature fomu chinhu (65 x 30 x 5 mm), i.e. inenge hafu yehukuru hwenguva dzose Raspberry Pi. Kutengesa kwatanga chete kuUK, European Union, USA, Canada neHong Kong; kuendesa kune dzimwe nyika kunovhurwa sezvo iyo isina waya module inosimbiswa. Mutengo weRaspberry Pi Zero 2 W imadhora gumi nemashanu (yekuenzanisa, mutengo weRaspberry Pi Zero W bhodhi imadhora gumi, uye Raspberry Pi Zero imadhora mashanu; kugadzirwa kwemabhodhi akachipa kuchaenderera mberi).
Musiyano wakakosha pakati peiyo nyowani yeRaspberry Pi Zero modhi ishanduko yekushandiswa kweBroadcom BCM2710A1 SoC, padhuze neiyo yakashandiswa mumabhodhi eRaspberry Pi 3 (muchizvarwa chakapfuura cheZero mabhodhi, Broadcom BCM2835 SoC yakapihwa, sezviri mukati. yekutanga Raspberry Pi). Kusiyana neRaspberry Pi 3, kuderedza kushandiswa kwesimba, iyo processor frequency yakaderedzwa kubva ku1.4GHz kuenda ku1GHz. Tichifunga nezveyakawanda-yakarukwa sysbench bvunzo, iyo SoC yekuvandudza yakaita kuti ikwanise kuwedzera kuita kwebhodhi nekashanu (iyo SoC nyowani inoshandisa quad-core 5-bit Arm Cortex-A64 CPU pachinzvimbo cheimwe-musimboti 53- zvishoma ARM32 ARM11JZF-S).
Sezvakaita mushanduro yapfuura, Raspberry Pi Zero 2 W inopa 512MB ye RAM, Mini-HDMI port, maviri Micro-USB ports (USB 2.0 ine OTG uye magetsi emagetsi), microSD slot, 40-pini GPIO yekubatanidza. (isina kutengeswa), Inosanganiswa vhidhiyo uye kamera zvinobuda (CSI-2). Bhodhi racho rine chipu chisina waya chinotsigira Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2 uye Bluetooth Low Energy (BLE). Kuti upfuure chitupa cheFCC uye kudzivirira kubva mukukanganiswa kwekunze, iyo isina waya chip mubhodhi nyowani yakafukidzwa nesimbi casing.
GPU yakabatanidzwa muSoC inotsigira OpenGL ES 1.1 uye 2.0, uye inopa maturusi ekukurumidzira kudhikodha mavhidhiyo muH.264 uye MPEG-4 mafomati ane 1080p30 quality, pamwe ne encoding muH.264 format, iyo inowedzera huwandu hwekushandiswa kwe. bhodhi rine akasiyana multimedia zvishandiso uye masisitimu eimba yakangwara. Nehurombo, saizi ye RAM inogumira ku512 MB uye haigone kuwedzerwa nekuda kwekuremerwa kwemuviri webhodhi saizi. Kupa 1GB ye RAM kunoda kushandiswa kweakaomarara akawanda-layer dhizaini, iyo vanogadzira havasati vagadzirira kuita.
Dambudziko guru pakugadzira Raspberry Pi Zero 2 W bhodhi raive kugadzirisa nyaya yekuisa LPDDR2 SDRAM ndangariro. Muchizvarwa chekutanga chebhodhi, chiyeuchidzo chaive mune imwe nhanho pamusoro peiyo SoC chip, yakashandiswa uchishandisa PoP (package-on-package) tekinoroji, asi nzira iyi haina kukwanisa kuitwa mumachipi matsva eBroadcom nekuda kwekuwedzera saizi yeSoC. Kugadzirisa dambudziko iri, pamwe neBroadcom, shanduro yakakosha yechip yakagadzirwa, umo ndangariro yakabatanidzwa muSoC.
Rimwe dambudziko raive rekuwedzera kwekupisa kupisa nekuda kwekushandisa processor ine simba. Dambudziko rakagadziriswa nekuwedzera mhangura dzakakora kubhodhi kubvisa uye kubvisa kupisa kubva kune processor. Nekuda kweizvi, huremu hwebhodhi hwakawedzera zvinooneka, asi nzira yakaonekwa seyakabudirira uye yaikwana kudzivirira kupisa zvakanyanya pakuita nguva isina muganho LINPACK linear algebra stress test pane ambient tembiricha ye20 degrees.
Pamidziyo inokwikwidza, chinhu chepedyo kuRaspberry Pi Zero 2 W iChinese board Orange Pi Zero Plus2, inoyera 46x48mm uye inouya nemadhora makumi matatu neshanu ne35MB ye RAM uye Allwinner H512 chip. Iyo Orange Pi Zero Plus3 board ine 2 GB EMMC Flash, ine yakazara HDMI port, TF Kadhi slot, USB OTG, pamwe nevanobatika ekubatanidza maikorofoni, infrared receiver (IR) uye maviri ekuwedzera USB ports. Bhodhi racho rine quad-core Allwinner H8 (Cortex-A5) processor ine Mali Mali53 GPU kana Allwinner H450 (Cortex-A3) ine Mali7MP400 GPU. Panzvimbo peiyo 2-pini GPIO, yakapfupikiswa 40-pini yekubatanidza inopihwa, inoenderana neRaspberry Pi B+. Iyo isina simba Orange Pi Zero 26 board inowanikwawo, asi inouya ne2 GB ye RAM uye Ethernet port mukuwedzera kune Wi-Fi.
