Motor Shield V2 question

[dmen]

Hi there, I have the motor shield and trying to figure out if it will work with this stepper:
https://www.amazon.com/dp/B00PNEQKC0

It says 2.0A and 1.4ohm resistance. I don't understand how to apply Ohms law to know if the driver will work. Says 12V but 2 * 1.4 = 2.8? If I use this stepper will it just draw what it can from the driver and not have quite as much torque? Please help.

2A/phase is what the motor is rated to handle without overheating. Without any active current limiting, the current it will actually draw will obey Ohm's Law: I = V/R. https://learn.adafruit.com/all-about-st ... he-stepper

At 12v, your motor will try to draw 12v / 1.4ohms = 8.6A per phase (17.2A total). Clearly, the motor was designed for use with a current limiting 'chopper' type driver. Unfortunately, the motor shield does not have current limiting.

We do have the DRV8833. But it is limited to about 10v. https://www.adafruit.com/product/3297

www.pololu.com carries a much wider selection of current limiting stepper drivers.
