This is a retired product, but fear not as there is a newer, better version available: PRT-10804

Replacement: PRT-10804. We've made some minor changes to this board layout to prevent the barrel jack from hanging over the edge. This page is for reference only.
Description: 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.
Input power can be supplied to either the DC barrel jack or the two pin header labeled + and -. Output power is supplied to the pins labeled GND and VCC. Board has both an On/Off switch and a voltage select switch (3.3V/5V).
The two pairs of GND and VCC pins are spaced such that when connected to our Basic Breadboard both power busses will be powered.
