Dear all,
In the description of this product, it’s mentionned a ptentiometer has to be added to adjust engine current.
Would you mind pleas being more explicit how to proceed?
Many thanks in advance.
Best regards

Hi,
We have contacted DFRobot for more details on how to vary the maximum current output of the Dual Bipolar Stepper Motor Controller for Arduino. We will post their reply here as soon as we get it.
Best Regards,
We have received a reply from DFRobot. Unfortunately, this new version of the RB-Dfr-539 doesn’t support adjustable maximum current with a potentiometer. We have updated our product page.
The Pololu 8-35V 2A Single Bipolar Stepper Motor Driver A4988 has an onboard potentiometer to set the maximum current output. Please contact us through our Support Center if you want to exchange the RB-Dfr-539 with the A4988.
