enriquejulio:
Could you tell if it is posible to drive a an unipolar stepper motor with Arduino and a SLA7020M chip, both obtained from an old Epson 810 printer?
Help or guidance will be greatly appreciated!
Hey, did you found how to drive stepper using sla7020 ?
I also got the same printer ic. I found that there must be two signal inputs for the driver. Please inform me if you succeed in this.
