Hey !I'd like to control a stepper motor (working at 2.8V and 2A/phase) with a A4988, I have a 12V 5A external power supply to power everything.I found a lot of threads showing how to control the current you give to the motor but not about the voltage.
So here is my question:Can I reduce the voltage (12V) of my power supply to 2.8V for my stepper motor ?
Can it be handled on the board or must I buy a buck converter ?Thx !
I hope you realise the nonsensical ratings the seller gives you?1.7A current. Sensible.30Ω winding resistance. Well, sounds a bit high but within the realm of possibilities.12V supply. Unusual for steppers that are indeed current driven.But... since when does 30 * 1.7 equal 12?
I've learned to ignore the nonsense written in e-bay and similar ads, instead look up the datasheet of the part.
