Projekt Raspberry Pi ozn\u00e1mil pr\u00edchod novej gener\u00e1cie dosky Raspberry Pi Zero W, ktor\u00e1 kombinuje mal\u00e9 rozmery a podporu Bluetooth a Wi-Fi. Nov\u00fd model Raspberry Pi Zero 2 W je vyhotoven\u00fd v rovnakom mini form\u00e1te (65 x 30 x 5 mm), t.j. pribli\u017ene dvakr\u00e1t men\u0161\u00ed ne\u017e be\u017en\u00fd Raspberry Pi. Predaj sa zatia\u013e za\u010dal len vo Ve\u013ekej Brit\u00e1nii, Eur\u00f3pskej \u00fanii, USA, Kanade a Hongkongu, dod\u00e1vky do ostatn\u00fdch kraj\u00edn bud\u00fa spr\u00edstupnen\u00e9 po schv\u00e1len\u00ed certifik\u00e1cie bezdr\u00f4tov\u00e9ho modulu. Cena Raspberry Pi Zero 2 W je 15 dol\u00e1rov USA (na porovnanie cena dosky Raspberry Pi Zero W je 10 dol\u00e1rov, a Raspberry Pi Zero 5 dol\u00e1rov, v\u00fdroba lacnej\u0161\u00edch dosiek bude pokra\u010dova\u0165).

K\u013e\u00fa\u010dov\u00fdm rozdielom novej modelu Raspberry Pi Zero je prechod na pou\u017eitie SoC Broadcom BCM2710A1, podobn\u00e9ho tomu, ktor\u00fd sa pou\u017e\u00edval v dosk\u00e1ch Raspberry Pi 3 (v predch\u00e1dzaj\u00facej gener\u00e1cii dosiek Zero sa dod\u00e1val SoC Broadcom BCM2835, ako v prvom Raspberry Pi). Na rozdiel od Raspberry Pi 3 bola frekvencia procesora zn\u00ed\u017een\u00e1 z 1,4 GHz na 1 GHz, aby sa zn\u00ed\u017eila spotreba energie. Pod\u013ea viacvl\u00e1knov\u00e9ho testu sysbench aktualiz\u00e1cia SoC umo\u017enila zv\u00fd\u0161i\u0165 v\u00fdkonnos\u0165 dosky p\u00e4\u0165kr\u00e1t (v novom SoC je pou\u017eit\u00fd \u0161tvorjadrov\u00fd 64-bitov\u00fd CPU Arm Cortex-A53 namiesto jednobodov\u00e9ho 32-bitov\u00e9ho ARM11 ARM1176JZF-S). <\/p>\n

Rovnako ako v predch\u00e1dzaj\u00facej ed\u00edcie, Raspberry Pi Zero 2 W pon\u00faka 512 MB RAM, port Mini-HDMI, dva porty Micro-USB (USB 2.0 s OTG a port na nap\u00e1janie), slot microSD, 40-kontaktn\u00fd konektor GPIO (nie je osaden\u00fd), v\u00fdvody pre kompozitn\u00e9 video a kameru (CSI-2). Doska je vybaven\u00e1 bezdr\u00f4tov\u00fdm \u010dipom, ktor\u00fd podporuje Wi-Fi 802.11 b\/g\/n (2.4GHz), Bluetooth 4.2 a Bluetooth Low Energy (BLE). Na certifik\u00e1ciu FCC a ochranu pred vonkaj\u0161\u00edmi ru\u0161eniami je bezdr\u00f4tov\u00fd \u010dip v novej doske chr\u00e1nen\u00fd kovov\u00fdm krytom. <\/p>\n

Hlavn\u00fdm probl\u00e9mom pri navrhovan\u00ed dosky Raspberry Pi Zero 2 W bolo rozhodovanie o umiestnen\u00ed pam\u00e4te LPDDR2 SDRAM. V prvej gener\u00e1cii dosky bola pam\u00e4\u0165 umiestnen\u00e1 v dodato\u010dnej vrstve nad \u010dipom SoC, realizovanej pomocou technol\u00f3gie PoP (package-on-package), ale v nov\u00fdch \u010dipoch Broadcom sa tento sp\u00f4sob realizova\u0165 nepodarilo kv\u00f4li zv\u00fd\u0161eniu ve\u013ekosti SoC. Na vyrie\u0161enie vzniknutej ot\u00e1zky bol v spolupr\u00e1ci s firmou Broadcom vyvinut\u00fd \u0161peci\u00e1lny variant \u010dipu, v ktorom bola pam\u00e4\u0165 integrovan\u00e1 do SoC.
