Kua panuitia e te Kaupapa Raspberry Pi te waatea o te reanga hou o te papa Raspberry Pi Zero W, e whakakotahi ana i te rahi kiato me te tautoko Nihokikorangi me te Wi-Fi. Ko te tauira hou Raspberry Pi Zero 2 W he mea hanga i roto i te ahua ahua iti (65 x 30 x 5 mm), i.e. tata ki te haurua o te rahi o te Raspberry Pi. I tenei wa, kua timata nga hoko i roto i te UK anake, te Kotahitanga o Europi, nga USA, Canada me Hong Kong, ka tuwhera nga tuku ki etahi atu whenua i te mea ka tukuna e te waahanga ahokore te tiwhikete. Ko te Raspberry Pi Zero 2 W te utu mo te $15 (mo te whakataurite, ko te Raspberry Pi Zero W he $10 me te Raspberry Pi Zero he $5, ka mahi tonu nga papa iti ake).
Ko te rereketanga nui o te tauira hou Raspberry Pi Zero ko te whakawhiti ki te whakamahi i te Broadcom BCM2710A1 SoC, tata ki tera i whakamahia i roto i nga papa Raspberry Pi 3 (i nga reanga o mua o nga papa Zero, i tukuna te Broadcom BCM2835 SoC, penei i roto te Raspberry Pi tuatahi). Kaore i rite ki te Raspberry Pi 3, kua whakahekehia te auau o te tukatuka mai i te 1.4GHz ki te 1GHz hei whakaiti i te kai mana. Ma te whakatau i te whakamatautau sysbench maha-miro, ka whakaaetia e te whakahou SoC te whakanui ake i nga mahi o te poari ma te 5 nga wa (ko te SoC hou e whakamahi ana i te quad-core 64-bit Arm Cortex-A53 CPU hei utu mo te kotahi-matua 32-bit ARM11 ARM1176JZF-S).
Ka rite ki te putanga o mua, ko te Raspberry Pi Zero 2 W e tuku ana i te 512MB RAM, he tauranga Mini-HDMI, e rua nga tauranga Micro-USB (USB 2.0 me te OTG me te tauranga mo te tuku hiko), he mokowhiti microSD, he 40-pin GPIO. pane (kaore i te soldered), nga putanga mo te riipene whakaata me te kamera (CSI-2). Ko te poari he maramara ahokore e tautoko ana i te Wi-Fi 802.11 b/g/n (2.4GHz), Bluetooth 4.2, me te Bluetooth Low Energy (BLE). Hei tuku i te tiwhikete FCC me te whakamarumaru mai i nga pokanoa o waho, ka hipokina te maramara ahokore i roto i te papa hou ki te pouaka whakarewa.
Ko te GPU whakauru-SoC e tautoko ana i te OpenGL ES 1.1 me te 2.0, me te whakarato taputapu ki te whakatere i te whakawaehere ataata H.264 me MPEG-4 me te kounga 1080p30, me te whakawaehere H.264, e whakanui ana i te whakamahinga o te poari e nga momo taputapu rongorau me nga punaha mo whare atamai. Heoi ano, he iti te rahi o te RAM ki te 512 MB, a, kaore e taea te whakanui ake na te kaha o te rahi o te poari. Ko te tukunga o te 1GB o te RAM ka hiahia ki te whakamahi i tetahi hoahoa paparanga-maha uaua, kaore ano nga kaihanga kia rite ki te whakatinana.
Ko te wero hoahoa matua mo te papa Raspberry Pi Zero 2 W ko te whakaurunga LPDDR2 SDRAM. I te reanga tuatahi o te poari, i whakauruhia te mahara ki tetahi paparanga taapiri i runga ake i te maramara SoC, i whakatinanahia ma te whakamahi i te hangarau PoP (package-on-package), engari kaore i taea te whakamahi i tenei tikanga ki nga maramara Broadcom hou na te pikinga te rahi o te SoC. Hei whakaoti i tenei raruraru, me Broadcom, i whakawhanakehia he putanga motuhake o te maramara, i whakauruhia ai te mahara ki te SoC.
Ko tetahi atu raruraru ko te piki ake o te wera o te wera na te whakamahinga o te tukatuka kaha ake. I whakatauhia te raru ma te taapiri i nga papa parahi matotoru ki te papa hei tango me te whakakore i te wera mai i te tukatuka. I tino piki ake te taumaha o te poari na tenei, engari i mohiohia he angitu te powhiri, a, ka kitea he nui ki te karo i te wera i te wa e mahia ana he whakamatautau ahotea LINPACK linear algebra ahotea i te pāmahana ambient o 20 nga nekehanga.
O nga taputapu whakataetae, ko te mea tino tata ki te Raspberry Pi Zero 2 W ko te Orange Pi Zero Plus2 o Haina, e 46x48mm te ine ka tukuna mo te $35 me te 512MB RAM me te maramara Allwinner H3. Ko te poari Orange Pi Zero Plus2 kua whakauruhia ki te 8 GB EMMC Flash, he tauranga HDMI katoa, he mokamoka TF Card, USB OTG, me nga titi mo te hono i te hopuoro, he kaiwhiwhi infrared (IR) me etahi atu tauranga USB e rua. Ko te poari he mea hanga ki te Allwinner H5 (Cortex-A53) tapawhā-matua pūtukatuka me Mali Mali450 GPU ranei Allwinner H3 (Cortex-A7) me Mali400MP2 GPU. Engari i te 40-pin GPIO, he iti ake te pane 26-pin e hototahi ana ki te Raspberry Pi B+. Kei te waatea ano he poari Orange Pi Zero 2 iti ake, engari ka tae mai me te 1 GB o te RAM me te tauranga Ethernet hei taapiri atu ki te Wi-Fi.
