Hi guys,
I have some ULN2003 boards laying around, the ones with 5 outputs and a BI-POLAR stepper motor with 4 wires. Is there a way to connect them?
Thanks!

The point of unipolar stepper motor is to allow use of simpler driver (2 transistors per coil, bipolar requires H bridge). ULN2003 is such simpler driver. So I'm afraid that the answer is no.
