@Gordon, thanks for the response. I guess a S4 was in place that could handle 1A. I was surprised the Diode gave way and the trace(s) survived... I figured what happened: I created a complete shortcut of 5V to GND with the jumper on the ULN2003 driver board... I did see nothing but noticed the funny smell of a cocked plastic case...
