36v4 logic current requirements

Hi, I’m going to control the board from an ATmega328P chip at 3.3 V. I’m using a voltage regulator to power the 328, and I would like to know how much extra current I’ll need from my regulator to control the 36v4 digital logic?


I moved your post to the motor controllers/drivers and motors category since that seems more relevant.

I suspect you are asking about our High-Power Stepper Motor Driver 36v4 rather than the Tic 36v4 Stepper Motor Controller. I expect IOREF on the driver to take at most a few milliamps.


Hi Claire,

Yes, that is what I was asking about. Thank you. I will definately have a few mA to spare.
