I have successfully converted my 28byj-48 stepper motor from unipolar to bipolar and are driving it with a4988 driver. That works fine but since there is some noise I am considering changing driver into TMC2209 which is said to be very quiet.
My question is though is TMC2209 interchangeable with A4988? So if A4988 works together with 28byj-48 the TMC2209 will also be able to drive it? Can I basically now drive my 29byj-48 or any other bipolar stepper motors with either a4988 or TMC2209 or is there something to consider?
As I mentioned in your other post, the noise is coming from the motor windings when the current is chopped, not from the driver. You don't need a current limiting stepper driver for the 28BYJ motor.
