Hi, I have buy this stepper motor and I want to know which pololu I need. I don’t really know what to check to select the right drive.
The closest thing we have is our DRV8825 Stepper Motor Driver Carrier, which has a maximum current rating of 1.5A (the stepper motor you referenced has a maximum of 1.7A). Using the DRV8825 carrier should work if the current limiting has been set to a limit the driver can handle (1.5A), but limiting the current your stepper motor draws will also reduce its holding torque. If your application does not need all of the torque your stepper motor can deliver, you might be able to use this driver.
