    ​Dear Customer,

    It is indeed possible to use ST25DV02K-W2 to control a small DC motor. When a tag enters the RF field of the RF Reader/phone, the RF Reader/phone detects the ST25DV02K-W2 and programs one or 2 PWM outputs to control the DC motor when setting the proper duty cycle of the PWM signals

    An alternative that could be of interest for you is to control a stepper motor over NFC. A demo for ST25DV-PWM + STSPIN220 is available at: https://www.youtube.com/watch?v=HO0FQvtZbkg&lc=z23txbhx2z2vsr1b504t1aokg02h3disrqnu0mroaorobk0h00410.1563982207079128.

    Please let me know if you have any further question.

    Have a good day
