This is actually a Hardware snippet...
In many cases you want to use voltage higher than what the MC needs (5v or 3.3v), for example - when you attach motors, or if you need power directly from the source and not limited by the mb-102 current limitation, like I needed to run Raspberry pi by batteries.
I soldered one wire to the connections of the plug socket and from now on I need just to connect this pin to the required user.
The ground is common to the ground pins of the mb-102.
