Lub Arduino MKR ZERO yog siv los ntawm Atmel's SAMD21 MCU, uas muaj 32-ntsis ARMR CortexR M0+ core
MKR ZERO coj koj lub zog ntawm xoom hauv ib hom me me ua hauv MKR daim ntawv zoo Lub MKR ZERO board yog ib qho cuab yeej kev kawm rau kev kawm 32-ntsis daim ntawv thov kev loj hlob
Tsuas txuas nws mus rau lub computer siv lub micro-USB cable los yog fais fab nws los ntawm lub lithium polymer roj teeb. Txij li thaum muaj kev sib txuas ntawm cov analog converter ntawm lub roj teeb thiab lub rooj tsav xwm Circuit Court, lub roj teeb voltage kuj tuaj yeem saib xyuas.
Khoom taw qhia
MKR ZERO coj koj lub zog ntawm xoom hauv ib hom me me ua hauv MKR daim ntawv zoo.
MKR ZERO board yog cov cuab yeej kev kawm rau kev kawm 32-ntsis daim ntawv thov kev txhim kho. Nws muaj ib qho onboard SD connector nrog rau siab SPI interface (SPI1) uas cia koj ua si suab paj nruag ntaub ntawv yam tsis muaj ntxiv kho vajtse! Lub rooj tsavxwm yog siv los ntawm Atmel's SAMD21 MCU, uas muaj 32-ntsis ARMR Cortex⑧M0+ core.
Lub rooj tsavxwm muaj cov chips uas yuav tsum tau los txhawb lub microcontroller; Tsuas txuas nws mus rau lub computer siv lub micro-USB cable los yog fais fab nws los ntawm lub lithium polymer roj teeb. Txij li thaum muaj kev sib txuas ntawm cov analog converter ntawm lub roj teeb thiab lub rooj tsav xwm Circuit Court, lub roj teeb voltage kuj tuaj yeem saib xyuas.
