I have this shield for Arduino . The suppliers states that the driver is capable to move 2 unipolar stepper motors. https://www.sainsmart.com/collections/all-for-arduino/products/l293d-motor-drive-shield-for-arduino

But when I look the L293D diagram, it only mentions about a bipolar motor. I also noticed the shield provides connection to 5 5 wires for the stepper motor, but the unipolar motor needs 6 wires. Anyone use this shield with a Unipolar motor?

  • a unipolar motor can have 5 leads ..... circuitspecialists.com/blog/… – jsotola Mar 21 at 18:38
  • Thank you for your comment. I am aware that it is a practice to joint the supply voltage source to the two coils, but what troubles me the most is that this circuitry is capable to delivery current sequence for micro stepping to an unipolar motor. – Jose Enrique Calderon Mar 21 at 18:44
  • it is unclear what you mean by what troubles me the most – jsotola Mar 21 at 22:32
  • I dont see how this set up may source current to the four phases of a unipolar motor. Do you have a wiring diagram showing how the coils are energized from this board configuration? – Jose Enrique Calderon Mar 22 at 10:46
