Hi,

can I drive this Stepper: http://www.lipoly.de/index.php?main_page=product_info&products_id=240976

with this driver: http://www.lipoly.de/index.php?main_page=product_info&products_id=213391 http://www.ti.com/lit/ds/symlink/uln2003a.pdf

I still have some of these drivers. So this would be great.

Thanks Robert

No, that looks like a bipolar motor (4 wire), the ULN2003 can only be used for unipolar motors (5,6 or 8 wires). Bipolars require dual H-bridge or a bipolar chopper driver like A4988.

OK, thanks a lot. Got the difference now. :-)
