Hey everyone!

 

Here is a Stepper Motor BoosterPack I have been working on that utilizes the DRV8825. I just ordered the boards today and will be working on some code samples while I wait on them. The DRV8825 can drive one bipolar stepper motor or two DC motors. It has a 8.2-V to 45-V supply range with 2.5-A peak at 24-V. I tried to design for the full operating range of the chip while maintaining the BoosterPack size guidelines.

Let me know what you think! I am working on a BLDC Motor BoosterPack as well that I will post later.

Thanks. I have used headers in the past and it's a toss up as to which I prefer most. Barring unforeseen setbacks I should have something up and running for show and tell in 2 or 3 weeks.

I am interested.  Please keep us informed.
