Double checking my stepper motor driver selection

Projects General Guidance
1

I am relatively new to this.

I have two motors:

I am thinking about using either one of these stepper motor drivers.
Am I missing anything. Would these work?

Thanks!!

I didn't see the drive current specified in the data sheet for the stepper.
But it appears to be a small motor and I suspect the 8834 will have enough current capability for it. You'll need to adjust the ref voltage on the driver to get the current you need.

Be interested in knowing your project.

The maximum drive current for that tiny stepper can be calculated from the stated drive voltage (3V) and winding resistance (20R), or 150 mA.

So the DRV8834 will work fine. The manufacturer recommends instead a simple, low voltage H-bridge chip, the LB1836M.
