## Description

This is a very simple board that takes a 4-9V input voltage and outputs a selectable 1.8V 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/1.8V).

The two sets of four GND and VCC pins are spaced such that when connected to our Basic Breadboard both power busses will be powered.

Note: Headers are not supplied. You will need to supply your own headers to connect this board to a breadboard. Check below for some breakaway header strips.

Dimensions: 2.15x0.65"
