NEMA 11 with DRV8825

I was recommended the DRV8825 for driving my stepper motors at a time when I was looking at using NEMA 17's for my project, however I am now using NEMA 11's and ordered everything without thinking that they might not be compatible!

Here are the steppers: Pololu - Stepper Motor: Bipolar, 200 Steps/Rev, 28×32mm, 3.8V, 0.67 A/Phase

The voltage range for the DRV8825 is supposedly 8.2 - 45V and the motors are rated at 3.8V..

Are the drivers and motors still compatible?


… the components are compatible.
The driver‘s voltage is not an issue as it drives the connected stepper via current.
So what you need to do is, to check the Maximum current of your stepper motor and adjust the current limit of the driver to that value.

Though you need to pay attention to the voltage with which you want to operate the driver - this should be in the range of about 12V and above to ensure that the voltage drop of the motor is covered.
