No kēia manawa pono mākou a pau e ʻoluʻolu me ka Piʻi Piʻi 4, akā e hiki koke mai ana ka Raspberry Pi 5. ʻO ka mana hou i hoʻomākaukau ʻia e ka Raspberry Pi Foundation a ʻike ʻole ʻia. Eia naʻe, ke hoʻomaka nei e ʻike ʻia kekahi mau kikoʻī o ka SBC hou.
Nui ʻike ʻole ʻia e hoʻoholo ʻia, e like me ka hana a i ʻole nā mea kāhāhā e paʻa ai kēia bale hou no mākou... a me kekahi mau mea maopopo a mākou e haʻi aku ai iā ʻoe.

He aha ka SBC?
No ka poe ike ole, a SBC (Kekahi Papa Komohana) he lolouila piha ia ma ka PCB a i ka papa kaapuni pai. Hoʻolālā ʻia kēia mau papa e hoʻokomo i nā mea pono a pau o ke kamepiula, e like me ka processor, RAM, flash storage, input/output ports, a i kekahi mau hihia, ʻo nā pilina pūnaewele a me nā peripheral hou aʻe.
ʻO kāna mau mea maikaʻi, kumukūʻai kūpono, a me ka versatility, ua kaulana loa nā SBC i waena o nā mea aloha pāʻani. DIY, nā mea hana, nā haumāna, nā mea hoʻomohala, a me nā mea hoihoi o ka ʻenehana. Mai ka ʻike ʻana o ka Raspberry Pi, ua nui nā papahana i hoʻokumu ʻia ma ka mākeke, e like me BeagleBone, Nvidia Jetson, ASUS Tinker, Odroid, Odoo, Orange Pi, PINE Rock, Banana Pi, a me nā mea ʻē aʻe. Hoʻohana ʻia kēia mau papa i nā ʻano noi like ʻole e like me ka hoʻonaʻauao, home automation, robotics, embedded computing, prototyping and assorted DIY projects, weather stations, home automation system, robot control, etc.
He aha ka Raspberry Pi?
La ʻOiwi Pi he pūʻulu o nā SBC i hoʻomohala ʻia e ka Raspberry Pi Foundation, kahi hui aloha ma UK, a ʻo Eben Upton ka mea nāna i hoʻokumu. Ua hoʻolālā ʻia kēia mau papa liʻiliʻi me ka manaʻo o ka hoʻolaha ʻana i ka hoʻonaʻauao kamepiula a me ka helu haʻahaʻa haʻahaʻa a me ka hoʻolaha ʻana i nā papahana open source. Ua lilo ka Raspberry Pi i mea kaulana loa ma muli o kona kumukūʻai haʻahaʻa, ka nui paʻa, a me ka versatility.
I nā makahiki, ua hoʻokuʻu ʻia nā hiʻohiʻona diferent, kēlā me kēia me nā hiʻohiʻona ʻokoʻa a me nā hiʻohiʻona, akā ma ka maʻamau e komo pū me kahi kaʻina hana, RAM, nā awa USB, kahi pahu kāleka microSD (no ka ʻōnaehana hana a me ka waiho ʻana), nā awa HDMI no ka hoʻopili ʻana i kahi monitor a TV paha, GPIO (General Purpose Input/Output) no ka launa pū ʻana me nā ʻāpana uila, a pinepine hoʻi i kahi kikowaena pūnaewele, ma o Ethernet a i ʻole Wi-Fi.
Hoʻohana ʻia ka Raspberry Pi i kahi laulā o nā noiMai nā papahana aʻo hoʻonaʻauao a me ka coding a hiki i nā hoʻonā home automation, nā kikowaena pūnaewele māmā, nā kikowaena media, nā ʻōnaehana hoʻopili i hoʻopili ʻia, a me nā mea hou aku. ʻO kāna hui kaiaulu o nā mea hoʻomohala a me nā mea hoihoi i hana i ka nui o nā papahana a me nā kumuwaiwai i loaʻa ma ka pūnaewele, e lilo ia i mea hana ikaika no ka poʻe hoihoi i ka ʻike kamepiula a me ka uila. ʻOiaʻiʻo, me ka Android, ʻelua ia o nā papahana hoihoi loa no nā mea hana a me nā poʻe makemake e aʻo ma ka hana ʻana.
Hiki i nā hiʻohiʻona o ka Raspberry Pi 5
Ua ʻike ʻia e hiki mai ana ka Raspberry Pi 5 e hoʻoponopono i kekahi mau pilikia e hoʻopilikia nei i ka Raspberry Pi 4, a me ka hoʻomaikaʻi ʻana i ka hana a lawe mai i nā hiʻohiʻona hou aʻe. No ka laʻana, ʻo kekahi o nā pilikia nui me ka SoC hou o kēia SBC ʻo ia wela loa, e koi ana e hoʻohana i ka heatsink a i ʻole ka peʻahi no ka hoʻomaha maikaʻi. A ʻo kēia hoʻi ka hihia me ka Raspberry Pi 5 hou, e lawe mai i kahi SoC ikaika loa, a me ka TDP kiʻekiʻe. Hiki paha ke hoʻokō i kahi ʻōnaehana hoʻoilo?
Wahi a nā hōʻike hou loa, hiki i ka Raspberry Pi 5 ke hōʻike i kahi CPU Hoʻonui ʻia ʻo 76-bit ARM Cortex-A64 (quad-core ma muli o ARMv8.2), e hana ana ma luna o 2 GHz, i hui pū ʻia me kahi Mali GPU. E hui pū ʻia kēia ʻāpana silika a hiki i ka 16 GB o LPDDR5 SDRAM RAM (ma ke ʻano B), ʻoiai ke manaʻo ʻia nei nā ʻano like ʻole 4 GB a me 8 GB. ʻO ia, kahi mea e like me ka mea a mākou e ʻike nei ma ka Raspberry Pi 4.
No nā pili, aia paha iā ʻoe hoʻokahi pālua o nā awa HDMI 2.1, mau awa USB he nui (kekahi o ia mau USB-C), slot kāleka microSD, DC 5V GPIO, 2,4GHz a me 5,0GHz kākoʻo WiFi, me Bluetooth 5.2 no ka hoʻohui maikaʻi ʻana a me ka syncing me nā polokalamu ʻē aʻe.
I ka wā e pili ana i nā kikoʻī, e pili ana i nā hōʻike i hāʻawi ʻia e nā kumu kokoke i ke kumu Raspberry Pi, ʻo ke kumukūʻai kekahi ʻano e mālama ʻia me kahi paʻakai. Ua manaʻo ʻia ʻo ke kumu hoʻohālike hou hiki ke loaʻa ke kumukūʻai kiʻekiʻe, i ʻōlelo ʻia ma kahi o 150 euros. Eia kekahi, ua hoʻolālā ʻia e hāʻawi ʻia kekahi mau hiʻohiʻona me nā koho mālama like ʻole, me kahi kumu hoʻohālike komo me ke kumukūʻai o 30 euros, e like me ka Raspberry Pi mua.
ʻOiai ʻaʻohe hoʻolaha kūhelu i hoʻolaha ʻia, aia nā hōʻailona ikaika o ka Ke kūkulu ʻia nei ʻo Raspberry Pi 5 a hiki ke hoʻokuʻu ʻia i ka wā e hiki mai ana, ma 2024 paha…
He manawa maikaʻi no RISC-V
Hōʻike mau ʻia ka Raspberry Pi e kahi manaʻo ikaika loa i ka mea wehe, ʻo ia hoʻi, ma ke kumu hāmama. ʻO kaʻoiaʻiʻo, ua hana ka Raspberry Pi Foundation mai kahi ʻōnaehana hana manuahi, e like me Raspberry Pi OS (i kapa ʻia ʻo Raspbian ma mua), a hoʻokumu ʻia ma Debian, me ka hoʻohui ʻana i nā mea hoʻokele pono no kēia SBC i manuahi pū kekahi, etc. Eia nō naʻe, me ka lako, ʻaʻole i lawe ʻia kēlā hana, a ʻo kahi mea like paha me ka mea a Android i hoʻolako ai i manaʻo ʻia, ʻo ia ka papa hana hoʻomohala hou aʻe.
I kēia manawa, mahalo iā ka hiki ana mai o RISC-V, e like me nā mea hoʻokūkū ʻē aʻe o ka Raspberry Pi i hana ai, e loaʻa i nā mea e pono ai e piʻi i luna a loaʻa nā lako e pili ana i kēia ISA. ʻOiai ke hāʻawi nei nā CPU RISC-V i nā hopena maikaʻi loa a loaʻa nā ʻano like me ARM, ʻoiaʻiʻo nō hoʻi ʻaʻole i like ka nui o nā pūʻulu i hōʻuluʻulu ʻia no kēia hoʻolālā, e like me ka ARM. ʻO kēia paha kekahi o nā pilikia nui i kēia manawa. Eia nō naʻe, aia ka hoʻohālikelike piha me Linux a me nā pūʻulu liʻiliʻi.
ʻOiaʻiʻo, makemake nui nā mea pā o ka papahana i ka ʻO Raspberry Pi 5, a i ʻole Raspberry Pi V, e hui pū ʻia me nā pahu RISC-V. He manawa maikaʻi nō ia no kēia hui ʻana, e like me ka mana. Ma ka ʻaoʻao ʻē aʻe, ʻike ʻia nā mea a pau ʻaʻole like ia ...
