Arduino mkr1000 to drive a stepper driver

Hi guys,

I was wondering if I can drive a stepper driver using Arduino mkr1000.
I am afraid the 3V3 will not be enough.
I attached the expected voltage diagram for the driver.
It may be just enough but I don’t want to risk it either.
Thank you.

The document says around 3.5V to be expected as digital signal.
Can I use 3.3V? Is this going to be enough do you think?

I wonder is there another document that specifies the electrical characteristics - particularly the lowest signal voltage that is reliably considered to be HIGH.

I may have missed something but on the basis of what I have seen in the document you have linked to I would not be confident that a 3.3v microprocessor would be sufficient. Can you afford to try it and get a 5v Arduino if it does not work with the 3.3v one?

Thank you.

I have an arduino uno which works perfectly.

I use advancedfirmata to generate signals for the driver.

I was planning to use mkr1000 so that I can use the device over wifi. That's the reason I am changing the arduino board.
