    Video: Setting the Current Limit on Pololu Stepper Motor Driver Carriers

    - 13 June 2016

    The trimmer pot on the DRV8825 is of poor quality. It drifts in its setting and the metal ring on top is very fragile and subject to coming loose. I have made it my practice to remove the trimmer and wire on a larger but better quality trimmer. You use the same type trimmer on your adjustable-output switching regulators. Please consider upgrading these trimmers.
