ʻO ka mea hope i kali ʻia i ka Raspberry Pi Zero i kapa ʻia ʻo Raspberry Pi Zero 2 W microcontroller ua lilo i luna. Hoʻohana ʻia ka microcontroller hou i wehe ʻia e ka Broadcom BCM2710A1 chipset, e like me ka mana hoʻomaka o ka Raspberry Pi 3. ʻO ka 1GHz Zero W kāki uila kelepona hiki ke piʻi i ʻelima mau manawa o ka wikiwiki o kona mua. Eia kekahi, hele mai ia me 512MB LPDDR2 RAM.
Hana ka papa hana hou me nā papahana IoT a me nā noi home akamai. I mea hoʻomanaʻo, ua hoʻomaka ka Raspberry Pi Zero i ka makahiki 2015. Ua hoʻonui mua ʻia ke kumukūʻai noi mua o ka Raspberry Pi ma mua o kēia makahiki.
ʻAʻole ʻo ka mea i hoʻokuʻu ʻia ʻo Pi Zero i ka lua i loko o nā ʻeke o nā mea kūʻai aku. ʻO ka Raspberry Pi Zero kahi mana paʻa loa o ka stock Pi i kūʻai ʻia no $ 5 i ka makahiki 2015. Eia kekahi, ʻaʻole ia i hāʻawi i ka I / O kiʻekiʻe. Ma 2017, ua hoʻonui ʻia kona mau mana e hoʻokomo i ka Bluetooth a me Wi-Fi.
Ua hoʻokuʻu ʻia kēia mana hou e like me ka Pi Zero W no $ 10. ʻO ka mea pōʻino, ʻaʻole i loli ka hana, ʻoiai ʻaʻohe wahi e pāʻani ai. Eia naʻe, ua loli nā mea āpau me ka Raspberry Pi Zero 2 W.
Nā kikoʻī kikoʻī ʻo Raspberry Pi Zero 2 W
Mālama ka Pi Zero 2 W i nā ana kino a me ke ʻano o ka Raspberry Pi Zero kumu. Eia nō naʻe, aia ʻekolu mau cores hou. Eia kekahi, hoʻohana ʻia ka papa e ka quad-core 64-bit Arm Cortex-A53 processor clocked ma 1GHz. ʻO ka hiʻohiʻona kaulana loa o ka papa ʻo ka Raspberry Pi RP3A0 SIP (pūnaewele i loko o ka pūʻulu). Eia kekahi, hele mai ka Raspberry Pi Zero 2 W me 512MB LPDDR2 SDRAM. Eia kekahi, hele mai ia me Broadcom BCM2710A1 chipset.
Ma ke ʻano o ka hoʻohui ʻana, loaʻa i ka papa kahi port USB 2.0, ʻelua mau awa Micro-USB no ka mana, a me hoʻokahi awa Mini-HDMI. Eia kekahi, kākoʻo ia i ka Bluetooth v4.2 a me 802.11GHz IEEE 2,4 b / g / n LAN uea. Loaʻa pū kekahi i ka hoʻopāpā H.264 (1080p30), MPEG-4 (1080p30) decoding, a me OpenGL ES 1.1, 2.0 kiʻi. H.264 no ka nānā wikiō ʻoi aku.
Ma luna o kēlā, ua hoʻonohonoho hou ka Raspberry Pi Zero 2 W i nā wahi solder, wikiō composite, a me kahi mea hoʻohui kamera CSI-2.
Ka nui o ke kaula 65×30 mm. Ua wehe pū ʻia ka Raspberry Pi i kahi lako mana USB mana hou me kahi konohiki USB micro-B. Hiki i ka Raspberry Pi Zero 2 ke lako mana no ka mana i kāu Raspberry Pi 3B+ a i ʻole 3B. ʻO kona kumukūʻai kūʻai ma kahi o $8. Ma India, hele mai ia me kahi awa Type-D. Ua hoʻolaha hou ʻia ka Raspberry Pi 4 i 2019 no $35 no ke kumu hoʻohālike 1GB. Ua loaʻa kahi mana 2 GB no $45, aʻo kahi ʻano 4 GB i loaʻa no $55.
ʻO ke kumukūʻai a me ka loaʻa
ʻOkakopa 28 Raspberry Pi kūkala ʻiaua kūʻai ʻia ka Zero 2 W no $ 15. Hiki iā ʻoe ke kūʻai i ke kāleka kelepona ʻole Zero W mai kekahi mau hale kūʻai i helu ʻia ma ka pūnaewele kūhelu o ka hui ma Kanada, ʻAmelika Hui Pū ʻIa, United Kingdom, Hong Kong, a me ka European Union.
