Original Arduino UNO R4 WIFI/Minima motherboard ABX00087/80 yotumizidwa kuchokera ku Italy

Imayenda pa Renesas RA4M1(Arm Cortex@-M4) pa 48MHz, yomwe ili mwachangu katatu kuposa UNO R3. Kuphatikiza apo, SRAM yawonjezedwa kuchokera ku 2kB mu R3 mpaka 32kB ndi kukumbukira kwa flash kuchokera ku 32kB kupita ku 256kB kuti ikwaniritse ntchito zovuta kwambiri. Kuphatikiza apo, malinga ndi zofunikira za gulu la Arduino, doko la USB lidakwezedwa ku USB-C ndipo mphamvu yayikulu yamagetsi idakulitsidwa mpaka 24V. Bungweli limapereka basi ya CAN yomwe imalola ogwiritsa ntchito kuchepetsa mawaya ndikuchita ntchito zosiyanasiyana mwa kulumikiza matabwa owonjezera angapo, ndipo potsiriza, bolodi latsopanoli likuphatikizapo 12-bit analog DAC.

UNO R4 Minima imapereka njira yotsika mtengo kwa iwo omwe akufunafuna microcontroller yatsopano popanda zina zowonjezera. Kumanga pa kupambana kwa UNO R3, UNO R4 ndiye chitsanzo chabwino kwambiri komanso chida chophunzirira kwa aliyense. Ndi kapangidwe kake kolimba komanso magwiridwe antchito odalirika, UNO R4 ndiyowonjezera pachilengedwe cha Arduino ndikusunga zodziwika za mndandanda wa UNO. Ndikoyenera kwa oyamba kumene komanso okonda zamagetsi odziwa zambiri kuti agwiritse ntchito ntchito zawo.

Pchilungamo

● Zida zam'mbuyo zimagwirizana

UNO R4 imasunga ma pini omwewo ndi 5V yogwiritsira ntchito magetsi monga Arduino UNO R3. Izi zikutanthauza kuti matabwa ndi mapulojekiti omwe alipo atha kutumizidwa mosavuta ku matabwa atsopano.

● Zida zatsopano zoyendera

UNO R4 Minima imabweretsa zotumphukira zingapo, kuphatikiza 12-bit Dacs, CAN bus, ndi OPAMP. Zowonjezera izi zimapereka magwiridwe antchito komanso kusinthasintha pamapangidwe anu.

● Kukumbukira kwambiri ndi wotchi yothamanga

Ndi kuchuluka kosungirako (16x) ndi mawotchi (3x), UNO R4Minima imatha kuwerengera bwino kwambiri ndikusamalira ma projekiti ovuta. Izi zimathandiza opanga kupanga mapulojekiti ovuta komanso apamwamba

● Kuyankhulana kwapachipangizo kudzera pa USB-C

UNO R4 imatha kutsanzira mbewa kapena kiyibodi ikalumikizidwa ndi doko lake la USB-C, chinthu chomwe chimapangitsa kukhala kosavuta kwa opanga kupanga mawonekedwe othamanga komanso ozizira.

● Kuchuluka kwamagetsi ndi mphamvu zamagetsi

Bolodi la UNO R4 litha kugwiritsa ntchito mphamvu mpaka 24V, chifukwa cha kapangidwe kake kabwino ka kutentha. Njira zingapo zodzitchinjiriza zimagwiritsidwa ntchito pamapangidwe ozungulira kuti achepetse chiwopsezo cha kuwonongeka kwa bolodi kapena kompyuta chifukwa cha zolakwika za ma waya ndi ogwiritsa ntchito osadziwika. Kuonjezera apo, zikhomo za RA4M1 microcontroller zimakhala ndi chitetezo chopitirira malire, chomwe chimapereka chitetezo chowonjezera ku zolakwika.

●Capacitive touch Thandizo

Chithunzi cha UNO R4. RA4M1 microcontroller yomwe imagwiritsidwa ntchito pamenepo imathandizira kukhudza kwapang'onopang'ono

● Yamphamvu komanso yotsika mtengo

UNO R4 Minima imapereka magwiridwe antchito pamtengo wopikisana. Bolodi ndi njira yotsika mtengo kwambiri, ndikulimbitsa kudzipereka kwa Arduino pakupanga ukadaulo wapamwamba kwambiri.

● Pini ya SWD imagwiritsidwa ntchito pochotsa zolakwika

Doko la SWD lomwe lili m'bwalo limapatsa opanga njira yosavuta komanso yodalirika yolumikizira ma probe owongolera a chipani chachitatu. Mbaliyi imatsimikizira kudalirika kwa polojekitiyi ndipo imalola kuthetsa vuto lililonse lomwe lingakhalepo.
