I-Arduino UNO R4, inyathelo elikhulu loluntu oluvulekileyo lomthombo

Kwiminyaka yakutshanje, iimodyuli ze-elektroniki ziye zanda kakhulu phakathi kwabangaqeqeshwanga kunye neengcali. Ingqikelelo yokwakha iinkqubo ze-elektroniki ukusuka ekwenziweni kwangaphambili, amacandelo atshintshanayo abonelela ngeenzuzo ezininzi, kubandakanywa neprototyping ekhawulezayo, ukugcinwa lula, kunye nokuguquguquka okukhulu koyilo.

Uno kwezona nkqubo zidumileyo zombane zemodyuli kwaye isetyenziswa ngokubanzi kwayeIqonga leArduino, Ibonelela ngendlela ekulula ukuyisebenzisa yokudala iiprojekthi ezisebenzisanayo zombane.

Arduino uye wazisa ukukhululwa kwe-Arduino UNO R4, indlalifa ye-UNO R3 kwaye into ethethwa yinkampani "kukutsiba okukhulu phambili" kuthotho oludumileyo lwee-microcontroller.

I-R4 ENYE iyakugcina uhlobo olufanayo, ukuhambelana kwekhaka, kunye nombane osebenzayo we-5V kunamanye amalungu osapho lwe-UNO. Ngaphantsi kwe-hood kukho i-4-bit Renesas RA1M4 Cortex-M32 iprosesa. isebenza kwi-48 MHz, ivumela ukuba isebenze ngokukhawuleza kathathu kune-UNO R3.

"Ngaphezu koko," ithi enye intengiso, "i-SRAM isuke kwi-2kB ukuya kwi-32kB, kwaye imemori ye-flash isuka kwi-32kB ukuya kwi-256kB ukulungiselela iiprojekthi ezinzima." Iyonke, i-Arduino ithi, i-UNO R4 iya kuziqhayisa ngokuphindwe kathathu ukuya kwi-16 ukunyuka kwesantya sewashi, imemori, kunye nokugcinwa kwe-flash.

UArduino wabhengeza:

Thina kwa-Arduino siyakuvuyela ukubhengeza uhlaziyo olutsha olutsha lwebhodi ye-UNO ye-iconic, eya kwandisa ingqikelelo yomthombo ovulekileyo weyona mveliso idumileyo nedumileyo, ngelixa inika uluntu lomenzi uphuculo ekudala lulindelwe ngokwemigaqo yokusebenza kunye nezinto ezinokwenzeka. .

Enyanisweni, i-Arduino UNO R4 igcina iimpawu eziyaziwayo zentsapho ye-UNO (ifomu eqhelekileyo, i-shield compatibility, i-voltage ye-5V yokusebenza, ukuqina okuyingqayizivele), ngelixa inika nto ingaphantsi kwe-Cortex®-M4. 32-bit. kunye nokunyuka kwe-3 ukuya kwi-16 kwisantya sewotshi, imemori, kunye nokugcinwa kwe-flash.

Ibhodi entsha, leyo iya kufumaneka kwi-Wi-Fi kunye ne "economy" iinguqulelo zeMinima, iza ne-12-bit analog DAC, kunye nokunye ukusebenza kunye nomgangatho wobomi uphuculo olufana ne-USB-C port kunye nokunyuka kwamandla aphezulu ukuya kwi-24V. Ukongezelela, ibhasi ye-CAN kunye ne-SPI port ivumela abasebenzisi ukuba "banciphise i-wiring kwaye baqhube imisebenzi eyahlukeneyo ngokuhambelana ngokudibanisa izihlangu ezininzi."

Inguqulelo yeWiFi iza nemodyuli ye-Espressif S3 WiFi, ukwandisa amathuba okudala abadali, abafundisi, kunye nabadlali bokuzilibazisa, ngelixa i-UNO R4 Minima iyindlela engabizi kakhulu kwabo bafuna i-microcontroller entsha ngaphandle kweempawu ezongezelelweyo.

IArduino UNO R4 ixhotyiswe ngeRenesas RA4M1 kwi-48 MHz (i-3 amaxesha xa kuthelekiswa ne-UNO R3), ngaphezu koko, i-SRAM iye yanda ukusuka kwi-2 ukuya kwi-32 KB kunye nememori ye-flash ukusuka kwi-32 ukuya kwi-256 KB ukuze ikwazi ukwenza iiprojekthi ezinzima.

Kwelinye icala, kuyakhankanywa ukuba Izibuko le-USB liphuculwe ukuya kwi-USB-C kwaye amandla ombane obonelelo aphezulu anyuswe ukuya kwi-24V ngoyilo oluphuculweyo lwe-thermal. Ibhodi inikezela ngebhasi ye-CAN, evumela abasebenzisi ukuba banciphise i-wiring kwaye baqhube imisebenzi eyahlukeneyo ngokuhambelana ngokudibanisa iziboniso ezininzi. Ekugqibeleni, ikhadi elitsha libandakanya i-12-bit analog-to-digital converter.

Ngokubanzi, i-Arduino UNO R4 yimpendulo yezicelo zophuculo kunye nohlaziyo oluvela kumphuhlisi kunye noluntu lwabenzi, ukwenza ukuqalisa ngeArduino kube lula kunangaphambili.

Ngokubhekiselele kwi-hardware ehambelanayo, i-pinout, i-voltage, kunye nefom factor ayitshintshi kwi-UNO R3, iqinisekisa i-hardware ephezulu kunye nokuhambelana kombane kunye nezikhuselo ezikhoyo kunye neeprojekthi. Kwicala lesoftware, umzamo omkhulu ubekwa ekwandiseni ukuhambelana ngasemva kunye nezona zidumileyo.

Kuyafaneleka ukukhankanya ukuba i-Arduino UNO R4 icwangciselwe ukuphela kukaMeyi, xa iinkcukacha ezingakumbi malunga neempawu zayo ziya kutyhilwa.
