This is a simple breadboard power supply module that is capable of 7-12V input voltage and selectable outputs (5V or 3.3V) regulated voltage.

All headers are 0.1" pitch for simple insertion into a 400 point  breadboard. It can be either powered from 7-12 DC power jack or from USB power.  You can select 5v or 3.3v supply by using the on board switch. Through this board, you can give power to both power lanes of the breadboard.
