Hi,
Since I've used a Netduino in a few projects, I've found that I can always group my ground pins to the same wire. In some instances I've found I can group my negatives, too.
I'm trying to figure out why, and when this is a good/bad idea. When this is acceptable, does it always have to be the same supply voltage/current? What are the rules behind this?
Thank you!

Hi Reactive,
You're question is quite simular to this one:

I think Mario his explaination on this thread is a very good one. Or at least, I did understand it

Thanks Stefan.

Biggest fault of Netduino? It runs by electricity.
