E sebetsa ho Renesas RA4M1(Arm Cortex@-M4) ho 48MHz, e lebelo ka makhetlo a mararo ho feta UNO R3. Ho feta moo, SRAM e eketsehile ho tloha ho 2kB ho R3 ho isa ho 32kB le memori ea flash ho tloha ho 32kB ho ea ho 256kB ho amohela merero e rarahaneng haholoanyane. Ho phaella moo, ho ea ka litlhoko tsa sechaba sa Arduino, boema-kepe ba USB bo ile ba ntlafatsoa ho USB-C 'me matla a mangata a matla a matla a ile a eketseha ho 24V. Boto e fana ka bese ea CAN e lumellang basebelisi ho fokotsa lithapo le ho etsa mesebetsi e fapaneng ka ho hokahanya mapolanka a mangata a ho atolosa, 'me qetellong, boto e ncha e boetse e kenyelletsa DAC ea analog ea 12-bit.
UNO R4 Minima e fana ka khetho e theko e tlaase bakeng sa ba batlang microcontroller e ncha ntle le likarolo tse ling. Ho ikahela katlehong ea UNO R3, UNO R4 ke mohlala o motle ka ho fetisisa le sesebelisoa sa ho ithuta bakeng sa motho e mong le e mong. Ka moralo oa eona o matla le ts'ebetso e tšepahalang, UNO R4 ke tlatsetso ea bohlokoa ho Arduino ecosystem ha e ntse e boloka likarolo tse tsebahalang tsa letoto la UNO. E loketse ba qalang le ba chesehelang lisebelisoa tsa elektroniki ba nang le boiphihlelo ho sebelisa merero ea bona.
Ptekatekano
● Hardware e tsamaellana morao
UNO R4 e boloka tlhophiso ea phini e tšoanang le motlakase oa 5V o sebetsang joalo ka Arduino UNO R3. Sena se bolela hore liboto tse ntseng li le teng tsa katoloso le merero li ka fetisetsoa habonolo ho liboto tse ncha.
● Li-peripheral tse ncha tse ka har'a sekepe
UNO R4 Minima e hlahisa mefuta e mengata ea lisebelisoa tse ka har'a board, ho kenyeletsoa 12-bit Dacs, CAN bese le OPAMP. Li-add-on tsena li fana ka ts'ebetso e atolositsoeng le bonolo bakeng sa moralo oa hau.
● Mehopolo e eketsehileng le oache e potlakileng
Ka ho eketseha ha bokhoni ba polokelo (16x) le clocking (3x), UNO R4Minima e ka etsa lipalo tse nepahetseng haholoanyane le ho sebetsana le merero e rarahaneng haholoanyane. Sena se lumella bahlahisi hore ba hahe merero e rarahaneng le e tsoetseng pele
● Puisano e sebetsanang le lisebelisoa ka USB-C
UNO R4 e ka etsisa toeba kapa keyboard ha e hokahantsoe le boema-kepe ba eona ba USB-C, e leng tšobotsi e nolofalletsang baetsi ho theha lihokelo tse potlakileng le tse pholileng.
● Lebelo le leholo la motlakase le botsitso ba motlakase
Boto ea UNO R4 e ka sebelisa matla ho fihla ho 24V, ka lebaka la moralo oa eona o ntlafalitsoeng oa mocheso. Mehato e mengata ea ts'ireletso e sebelisoa moralong oa potoloho ho fokotsa kotsi ea tšenyo ea boto kapa komporo e bakoang ke liphoso tsa wiring ke basebelisi ba sa tsebeng. Ho phaella moo, lithakhisa tsa RA4M1 microcontroller li na le tšireletso e feteletseng, e fanang ka tšireletso e eketsehileng khahlanong le liphoso.
● Tšehetso ea Capacitive touch
Boto ea UNO R4. Microcontroller ea RA4M1 e sebelisitsoeng ho eona ka tlhaho e ts'ehetsa capacitive touch
● E matla ebile e theko e tlaase
UNO R4 Minima e fana ka ts'ebetso e tsotehang ka theko ea tlhōlisano. Boto ke khetho e theko e tlaase haholo, e tiisang boitlamo ba Arduino ba ho etsa hore theknoloji ea maemo a holimo e fumanehe.
● SWD Pin e sebelisetsoa ho lokisa liphoso
Boema-kepe ba SWD ba onboard bo fa bahlahisi mokhoa o bonolo le o ts'epahalang oa ho hokahanya li-debugging probes tsa motho oa boraro. Karolo ena e tiisa ho ts'epahala ha morero mme e lumella ho lokisa mathata leha e le afe a ka bang teng.
