I like your design. I learnt a lot from it. I have an idea to make it stackable that you can take a lot further. It's on EAGLE. Please send me your email address if you're interested.

Hi Ben,
thank you! Nice to hear that it was useful for you. Sure I'm interested in your design. In the meantime I improved the design too, added a potentiometer to set the driving current. I'm going to use 0 Ohm resistors to make it stackable and will post the updated plans soon.
Max,
Thanks as well for the project. I assigned the exact thing (Booster Pack with the DRV8834) to students last week as a PCB layout project for learning how to use Eagle, and then I stumbled on your version a couple days ago. I am having them use through-hole components from bench stock for all but the DRV8834, so we'll have some differences. We had trouble finding the library component for the DRV8834, so I hope to snag it from your schematic. Any suggestions or updates would be appreciated. I left the design goals open so a one-motor stepper controller is the minimum, but I challenged then to come up with something they could stack to control three motors. We'll see what they come up with. Thanks again...
Mike
