Stepper motors

Parallax #27964

Unipolar, 12VDC, 7.5o step angle.  Wiring is
1. Orange
2. Yellow
3. Black
4.Brown
COM Red


Using the adafruit stepper motor shield, with a bipolar stepper from an HP scanner, there was a bad smell, little crack, and I think I just fried half of the shield.  Well only the first blown chip so far, so not bad.
