NickO 9 Posted May 25, 2013 Share Posted May 25, 2013 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. http://www.ti.com/product/drv8825 Let me know what you think! I am working on a BLDC Motor BoosterPack as well that I will post later.

bitbckt 0 Posted May 27, 2013 Share Posted May 27, 2013 Neat. I'll definitely be giving this a try in the near future. I prefer 4 pin Molex connectors for steppers, but the terminal block's flexibility is a nice feature. Thanks. Quote Link to post Share on other sites
NickO 9 Posted May 28, 2013 Author Share Posted May 28, 2013 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. Quote Link to post Share on other sites

NickO 9 Posted June 23, 2013 Author Share Posted June 23, 2013 Have the boards! Been in the process of moving places and just got my work station set back up. I'll try and get a video posted later this week cubeberg 1 Quote Link to post Share on other sites
NickO 9 Posted June 28, 2013 Author Share Posted June 28, 2013 Boards built and code written, just waiting on the motor to get here to see if it works! Quote Link to post Share on other sites
