Hi all!
Thank you ahead for your support.
I was wondering why DollyShield is only made for DC motors.
Is there a way I can adapt it to a stepper motor which btw I already managed to make it work with Arduino and a L298 driver?
Thanks again.

Marco, from my email earlier:
Quote:The DollyShield was designed to work with DC motors so as to provide a lowest-cost motion control solution that does not require additional electronics. It has four addressable I/O pins and two GND lines served out through the EXT_0 and EXT_1 2.5mm TRS connectors, so you could in theory easily adjust the firmware to also control two step/direction-style stepper drivers.
