UNO R4 zai zo cikin nau'i biyu, UNO R4 WiFi da UNO R4 Minima.
A cikin 'yan shekarun nan, na'urorin lantarki na zamani sun ƙara shahara tsakanin yan koyo da kwararru. Manufar gina tsarin lantarki daga abubuwan da aka riga aka kera, abubuwan da za a iya canzawa suna ba da fa'idodi da yawa, gami da samfuri da sauri, sauƙin kulawa, da mafi girman sassaucin ƙira.
Daya daga cikin shahararrun tsarin lantarki na zamani kuma yadu amfanis dandalin Arduino, Yana ba da hanya mai sauƙi don amfani don ƙirƙirar ayyukan lantarki masu ma'amala.
Arduino ya sanar da sakin Arduino UNO R4, magajin UNO R3 kuma abin da kamfanin ya ce shine "babban tsalle-tsalle" don shahararrun jerin na'urori masu sarrafawa.
Farashin R4 zai riƙe nau'i iri ɗaya, dacewar garkuwa, da ƙarfin aiki na 5V fiye da sauran membobin gidan UNO. A ƙarƙashin hular akwai mai sarrafa 4-bit Renesas RA1M4 Cortex-M32. yana aiki a 48 MHz, yana ba shi damar yin aiki sau uku da sauri fiye da UNO R3.
"A saman wannan," in ji wani talla, "SRAM ya tashi daga 2kB zuwa 32kB, kuma ƙwaƙwalwar ajiyar flash ya tashi daga 32kB zuwa 256kB don ɗaukar ayyuka masu rikitarwa." Gabaɗaya, Arduino ya ce, UNO R4 za ta yi alfahari da haɓaka sau uku zuwa 16 a saurin agogo, ƙwaƙwalwar ajiya, da ajiyar walƙiya.
Arduino ya sanar:
Mu a Arduino mun yi farin cikin sanar da wani sabon bita na hukumar UNO mai ban mamaki, wanda zai faɗaɗa manufar buɗaɗɗen mabuɗin mafi kyawun samfuri kuma sanannen samfuri, tare da baiwa al'ummar ƙera haɓakar da aka daɗe ana jira ta fuskar aiki da yuwuwar. .
A zahiri, Arduino UNO R4 yana riƙe da sanannun fasalulluka na dangin UNO (misali nau'i nau'i, dacewa da garkuwa, ƙarfin aiki na 5V, ƙarfi na musamman), yayin da yake ba da komai ƙasa da babban aiki Cortex®-M4. 32-bit. da haɓakar ninki 3 zuwa 16 a saurin agogo, ƙwaƙwalwar ajiya, da ajiyar walƙiya.
Sabuwar hukumar, wanda zai kasance a cikin Wi-Fi da "tattalin arziki" Minima versions, ya zo tare da 12-bit analog DAC, tare da sauran ayyuka da haɓaka ingancin rayuwa kamar tashar USB-C da matsakaicin ƙarfin samar da wutar lantarki zuwa 24V. Bugu da ƙari, bas ɗin CAN da tashar jiragen ruwa na SPI suna ba masu amfani damar "rage girman wayoyi da gudanar da ayyuka daban-daban a layi daya ta hanyar haɗa garkuwa da yawa."
Sigar WiFi ta zo tare da module ɗin Espressif S3 WiFi, faɗaɗa damar ƙirƙira ga masu ƙirƙira, malamai, da masu sha'awar sha'awa, yayin da UNO R4 Minima zaɓi ne mai tsada ga waɗanda ke neman sabon microcontroller ba tare da ƙarin fasali ba.
Arduino UNO R4 sanye take da Renesas RA4M1 a 48 MHz (sau 3 idan aka kwatanta da UNO R3), bugu da ƙari, an ƙara SRAM daga 2 zuwa 32 KB da ƙwaƙwalwar walƙiya daga 32 zuwa 256 KB don samun damar aiwatar da ayyuka masu rikitarwa.
A gefe guda, an ambaci hakan Tashar tashar USB ta haɓaka zuwa USB-C kuma matsakaicin ƙarfin wutar lantarki ya ƙaru zuwa 24V tare da ingantaccen ƙirar thermal. Hukumar tana ba da motar bas ta CAN, tana ba masu amfani damar rage wayoyi da gudanar da ayyuka daban-daban a layi daya ta hanyar haɗa nuni da yawa. A ƙarshe, sabon katin ya ƙunshi 12-bit analog-to-dijital Converter.
Gabaɗaya, Arduino UNO R4 ita ce amsar buƙatun ingantawa da sabuntawa daga masu haɓakawa da masu ƙirƙira, yana sa farawa da Arduino ya fi sauƙi fiye da kowane lokaci.
Dangane da daidaituwar kayan aiki, nau'in pinout, ƙarfin lantarki, da nau'in nau'i ba su canzawa daga UNO R3, yana tabbatar da iyakar kayan aiki da dacewa da lantarki tare da garkuwa da ayyukan da ake dasu. A gefen software, ana yin ƙoƙari mai yawa don haɓaka daidaituwa na baya tare da mafi mashahuri.
Yana da kyau a faɗi cewa Arduino UNO R4 an shirya shi a ƙarshen Mayu, lokacin da za a bayyana ƙarin cikakkun bayanai game da fasalinsa.
