This is a very simple board that takes a 6-12V input voltage and outputs a selectable 5V or 3.3V regulated voltage. All headers are 0.1" pitch for simple insertion into a breadboard. It can be either powered from 6-12 DC2.1 power jack or from USB power. The maximum current it can provide is 500mA.

This is a nice power supply. No issues at all. It holds a steady voltage and it has a switch on board to turn power on and off. It does have a power light also. It is dual voltage. 5V down one rail and 3.3 down the other.
