Ya it’s a very good deal alright. The shipping is fast too.
I ordered on Sunday and received them today.
I’ve been reading up on the best way to drive 2 of them from one DRV8825 and I’m not sure what to do yet. Connected in parallel I won’t be able to run the 2 of them at their rated current (not that I could anyway seeing as at that current they’d be above the glass transition temperature of the PLA mounts).
Connected in series they can be run at their rated current and there should still be enough overhead voltage as those motors are rated at 2.8V per phase and I’m using a 12v supply.
I think I’ll just test both configurations once the rest of my parts arrive and decide what works best.
