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?
