I-Arduino UNO R4, isinyathelo esikhulu somphakathi womthombo ovulekile

Eminyakeni yamuva, i-modular electronics isithandwa kakhulu phakathi kwezimfundamakhwela nezingcweti. Umqondo wokwakha amasistimu e-elekthronikhi kusukela ekwakhiweni kwangaphambili, izingxenye ezishintshashintshayo unikeza izinzuzo eziningi, okufaka i-prototyping esheshayo, ukunakekelwa okulula, kanye nokuguquguquka okukhulu kwedizayini.

Uno yamasistimu e-elekthronikhi aziwa kakhulu futhi esetshenziswa kabanzi futhiIsiteji se-Arduino, Inikeza indlela esebenziseka kalula yokudala amaphrojekthi e-electronic interactive.

I-Arduino umemezele ukukhululwa kwe-Arduino UNO R4, elandela i-UNO R3 futhi okushiwo inkampani "ukugxumela phambili okukhulu" ochungechungeni oludumile lwama-microcontroller.

I-ONE R4 izogcina isici sefomu elifanayo, ukuhambisana kwesihlangu, kanye ne-voltage yokusebenza engu-5V kunamanye amalungu omndeni we-UNO. Ngaphansi kwe-hood kukhona iphrosesa engu-4-bit Renesas RA1M4 Cortex-M32. isebenzisa i-48 MHz, eyivumela ukuthi isebenze ngokushesha okuphindwe kathathu kune-UNO R3.

"Ngaphezu kwalokho," kusho esinye isikhangiso, "i-SRAM isuke ku-2kB yaya ku-32kB, futhi inkumbulo ye-flash isuka ku-32kB yaya ku-256kB ukuze ikwazi ukwamukela amaphrojekthi ayinkimbinkimbi." Sekukonke, u-Arduino uthi, i-UNO R4 izoziqhayisa ngokukhuphuka okuphindwe kathathu kuya kweziyi-16 kwejubane lewashi, inkumbulo, nokugcinwa kwe-flash.

U-Arduino umemezele:

Thina kwa-Arduino sijabule ukumemezela ukubuyekezwa okusha kwebhodi eliyisakhiwo sodumo le-UNO, elizonweba umqondo womkhiqizo odumile nodumile womkhiqizo womthombo ovulekile, kuyilapho kunikeza umphakathi wabakhi ukuthuthukiswa okulindelwe isikhathi eside mayelana nokusebenza. kanye namathuba .

Eqinisweni, i-Arduino UNO R4 igcina izici ezaziwayo zomndeni we-UNO (isici sefomu elijwayelekile, ukuhambisana kwesihlangu, i-voltage yokusebenza engu-5V, ukuqina okungavamile), kuyilapho inganikezeli lutho olungaphansi kwe-Cortex®-M4. 32-bit esebenza kahle kakhulu. kanye nokwenyuka okuphindwe ka-3 kuya kwezingu-16 kwejubane lewashi, inkumbulo, nokugcinwa kwe-flash.

Ibhodi elisha, okuyinto izotholakala ngezinguqulo ze-Wi-Fi kanye “nezomnotho” Minima, ifika ne-12-bit analog DAC, kanye nokunye ukusebenza nokuthuthukiswa kwekhwalithi yokuphila okufana nembobo ye-USB-C kanye nokwenyuka okukhulu kwamandla kagesi ukuya ku-24V. Ukwengeza, ibhasi le-CAN kanye nembobo ye-SPI ivumela abasebenzisi ukuthi "banciphise izintambo futhi baqhube imisebenzi ehlukene ngokuhambisana ngokuxhuma izihlangu eziningi."

Inguqulo ye-WiFi iza nemojula ye-Espressif S3 WiFi, ukwandisa amathuba okudala abadali, othisha, nabazithandayo, kuyilapho i-UNO R4 Minima iyindlela engabizi kakhulu yalabo abafuna isilawuli esincane esisha ngaphandle kwezici ezingeziwe.

I-Arduino UNO R4 ifakwe i-Renesas RA4M1 ku-48 MHz (izikhathi ezingu-3 uma kuqhathaniswa ne-UNO R3), ngaphezu kwalokho, i-SRAM iye yanda kusukela ku-2 kuya ku-32 KB kanye nememori ye-flash isuka ku-32 kuya ku-256 KB ukuze ikwazi ukwenza amaphrojekthi ayinkimbinkimbi.

Ngakolunye uhlangothi, kushiwo lokho Imbobo ye-USB ithuthukiselwe ku-USB-C futhi umthamo omkhulu wevolthi wokuhlinzeka ukhuphuke waba ngu-24V ngomklamo oshisayo othuthukisiwe. Ibhodi lihlinzeka ngebhasi le-CAN, elivumela abasebenzisi ukuthi banciphise izintambo futhi baqhube imisebenzi ehlukene ngokuhambisana ngokuxhuma izibonisi eziningi. Ekugcineni, ikhadi elisha lihlanganisa i-analog-to-digital converter engu-12-bit.

Sekukonke, i-Arduino UNO R4 iyimpendulo yezicelo zokuthuthukiswa kanye nezibuyekezo ezivela kunjiniyela kanye nomphakathi wabakhi, okwenza ukuqalisa nge-Arduino kube lula kunangaphambili.

Ngokuqondene nokuhambisana kwezingxenyekazi zekhompuyutha, i-pinout, i-voltage, ne-form factor azishintshile ukusuka ku-UNO R3, okuqinisekisa ubuningi behadiwe kanye nokuhambisana kukagesi nezihlangu namaphrojekthi akhona. Ngasohlangothini lwesoftware, kwenziwa umzamo omkhulu ekwandiseni ukuhambisana okubuyela emuva nezithandwa kakhulu.

Kuhle ukusho ukuthi i-Arduino UNO R4 ihlelelwe ukuphela kukaMeyi, lapho imininingwane eyengeziwe mayelana nezici zayo izokwambulwa.
