Controller selection

What’s the correct Pololu controller for Wantai 42byghw811 motor (
I think drv8834 is the best selection but I’m not sure.
Thanks for your help.


We do not carry a stepper motor driver that can handle the 2.5A per phase that your stepper motor is rated for. The closest we have is the DRV8834 you mentioned or our DRV8825, depending on the voltage you want to run your stepper motor at. Neither of those drivers will allow your stepper motor to deliver its full torque.
