Rasberi Pi 3, sabon kwamiti na SBC daga Raspberry Pi Foundation, an gabatar da shi a cikin 2016. Ya fi shekara guda tun, wanda ga mutane da yawa ya haifar da sha'awar sabon tsarin hukumar SBC, samfurin da ke sabuntawa zuwa na yanzu. Abin da mutane da yawa suka kira Rasberi Pi 4.
Waɗanda suka samo Rasberi Pi sun kasance a bayyane kuma ba sa magana: Ba za a sami Rasberi Pi 4 a wannan lokacin ba. Koyaya, wannan baya nufin ba zamu iya tunani ko nema ba abubuwan haɗin da nan gaba Rasberi Pi 4 ya kamata su samu ko cewa ya kamata a yi la'akari da sigar ta gaba.
Ma'aunai da girma dabam
Ma'aunin wannan hukumar ta SBC ya fi mahimmanci kuma idan na gani a cikin watannin da suka gabata cewa sun saki sigogin rage Rasberi Pi, sigar ta 4 ba zata bar wannan fasalin ba. Misali Rasberi Pi 3 yana da waɗannan matakan milimita 85 x 56 x 17, matakan da za a yarda da su sosai (kuma a matsayin tabbaci na wannan muna da ayyuka da yawa da suke wanzu tare da wannan farantin) amma har yanzu ana iya rage shi.
Ayyuka kamar Rasberi Pi Slim nuna cewa tashar ethernet da tashoshin USB suna yin kaurin "kaɗan" da allon, kuma ana iya cire su don ƙara rage matakan hukumar. Zai yiwu Rasberi Pi 4 ya kamata ya bi waɗannan matakan kuma cire abubuwa kamar tashar ethernet ko maye gurbin tashar USB tare da microusb ko tashar USB-c. Ingoƙarin samun matakan ma'aunin Rasberi Pi Zero da Zero W zai zama kyakkyawan ƙira, ma'ana, ya kai 65 x 30 mm ba tare da hukunta wasu ayyuka kamar ƙarfi ko sadarwa ba.
chipset
Tattaunawa game da kwakwalwan kwamfuta ko kuma makomar chipset na Rasberi Pi 4 yana da matukar tsoro, amma zamu iya magana game da iko. Rasberi Pi 3 yana da 1,2 Ghz Quadcore SoC, guntu mai ƙarfi amma ɗan ɗan amfani ne idan aka kwatanta da ƙarfin wasu na'urorin hannu. Saboda haka, ina tsammanin Rasberi Pi 4 yakamata yana da aƙalla chipset ɗaya tare da tsakiya takwas. Kuma ba tare da wata shakka ba, raba GPU daga CPU akan allon. Wannan yana nufin ƙarin iko ga kwamitin kuma ta hanyar haɓaka iya yin ayyuka kamar yin hotuna ko bayar da mafi kyawu a fuska.
Wannan sinadarin shine mafi mahimmanci kuma muna sane cewa shine mafi tsaran gaske. Wannan shine dalilin da yasa nake tsammanin cewa Rasberi Pi Foundation zai canza kwakwalwan a cikin Rasberi Pi 4, tun da jarabawar tana da jinkiri kuma kusan ta wajaba, saboda haka tabbatar da jinkirin sabon sigar.
Ajiyayyen Kai
Sabbin nau'ikan Rasberi Pi sun ɗan magance matsalar adanawa. Kodayake babban ajiyar har yanzu ta hanyar tashar microsd, gaskiya ne cewa yiwuwar amfani da tashoshin USB azaman rukunin ɗakunan ajiya an haɗa su. Yawancin katunan Rasberi Pi suna da ciki har da modules na ƙwaƙwalwar eMMC, wani nau'i na ƙwaƙwalwar ajiya da sauri kuma mafi inganci fiye da pendrives. Zai yuwu, Rasberi Pi 4 yakamata ya sami darasi na wannan nau'in inda zai iya shigar da kernel software ko kuma ana iya amfani dashi azaman musayar ajiya
Amma mafi mahimmanci kuma mafi mahimmanci a cikin wannan shine ƙwaƙwalwar rago ko kuma yadda yawancin ƙwaƙwalwar rago ya kamata ta samu. Rasberi Pi 3 yana da 1 Gb na RAM, adadin da ke hanzarta ayyukan kwamitin rasberi kaɗan. Amma kaɗan zai fi kyau. Saboda haka, a nan gaba Rasberi Pi 4, samun 2 Gb na rago ba zai zama da mahimmanci kawai ba Maimakon haka, zai iya sanya Rasberi Pi har ya zama mafi amfani dashi, ƙarshe maye gurbin kwamfutar tebur don yawancin masu amfani.
Sadarwa
Batun sadarwa yana da matukar mahimmanci ga allon kamar Rasberi Pi. A lokacin sigar ƙarshe, wannan jigon bai canza ba da yawa, mafi haɓaka shine hada Wi-Fi da tsarin bluetooth. Rasberi Pi 4 yakamata yayi la'akari da wasu hanyoyin sadarwa kuma yayi tunanin ko fadada nau'in sadarwa ko a'a. Ni kaina nayi imanin hakan ya kamata a cire tashar ethernet daga allon. Wannan tashar jiragen ruwa na da matukar amfani amma kuma tana shafar girman kwamitin, kasancewar ana iya maye gurbinsa da tsarin Wi-Fi, wata fasahar kere-kere wacce ta yadu a duniya. Kari akan haka, akwai masu adaidaitawa daga wannan tashar zuwa tashar USB, saboda haka samun tashar USB, zamu iya samun tashar ethernet, idan da gaske muna bukatar wannan tashar ko kuma ba zamu iya samun tsarin Wifi ba.
Aikin bluetooth ya kasance babban taimako ga yawancin masu amfani, amma sigar ta 4 ta wannan hukumar na iya faɗaɗa adadin fasahohin mara waya, gami da fasahar NFC, fasaha mai ban sha'awa don ayyukan IoT. Samun NFC a cikin kwamiti na Rasberi Pi na iya zama mai ban sha'awa don haɗa na'urori da faɗaɗa ayyukan Rasberi Pi, kamar haɗawa tare da masu magana, smartv, da sauransu ... Abubuwan da za'a iya haɗa su da Rasberi Pi, amma NFC ya sauƙaƙa haɗi da saita waɗannan na'urori.
Babban tauraron Rasberi Pi ya kasance tashar GPIO koyaushe, tare da wasu abubuwa saboda ɗaruruwan sabbin ayyuka da aikace-aikacen da wannan tashar ke ƙarawa zuwa Rasberi Pi. Rasberi Pi 4 na iya gwada wannan abun kuma faɗaɗa tashar GPIO tare da ƙarin fil sabili da haka don iya bayar da ƙarin ayyuka, ayyuka masu tallafi idan kwakwalwar da aka yi amfani da ita ta fi ƙarfin gaske.
Kamar yadda muka yi tsokaci game da tashar ethernet, ana iya canza tashoshin USB kuma a maye gurbinsu ta tashar microsb ko kuma kai tsaye ta tashar USB-C, mashigai tare da canja wuri mafi girma kuma tare da ƙarami fiye da tashar USB ta gargajiya. Wannan canjin ba wai kawai yana bawa Rasberi Pi damar "siriri ƙasa" amma kuma yana ba da ƙarin iko ga kwamitin, yana tallafawa saurin canja wuri sama da tashar USB ta gargajiya.
