Little step-u motor power supply.
I have a Basic Stamp BOE and I'm wiring a Little Step-U as in the diagram below. I am using the Vdd and Vss of the Basic Stamp to power the logic section of the Little Step-U.
The documentation for the Little Step-U says the logic ground and motor ground are common and I confirmed it with a multimeter. My question is :
From the schematic, it does not seem to be an issue..

- If I use a separate 12V 5A power supply for the motor, will the separate grounds burn something in the circuit ?
From the schematic, it does not seem to be an issue..
