Stepper Motor Driver v2.3 2A $20 !!!

[Conan257]

I'd like to be able to use a pc power supply (12v) to power everything, but 12v is usually a little low...

Has anyone got any experience with using 12v to power stepper controllers/steppers? Mainly as i'd like a single psu for computer and steppers so I can house it all in a single box.

12v Was not enough for these drivers, I agree it would be nice to use a ATX supply as there cheap powerful plus you could use the 5v rail for I/O.

Other problem is you won't acheive anything like the same RPM at 12v you would expect at 24v

They are very nice drives for the money.
Where Roy scores is he' is a design engineer in real life and can do all this himself whereas others [ no names ] rip other designs off.

Where is shows is put one of Roy's boards on a scope whilst it's operating and see the signal.
Then do the same with other drives and see the dirty signal they turn out.

Couldn't agree more, I have had 8 of those boards and a few of the previous version without PS feature. Roy is great bloke and very helpful. I killed a couple of KIT boards by putting network resistor in wrong way and he fixed and returned them free of charge.
