Description

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

Dimensions: 2.15x0.65"

Features:

6-12V input voltage via barrel jack or 2-pin header 3.3V or 5V regulated output voltage 800mA Operating Current ON/OFF switch Output voltage select switch Power status LED PTC fuse protected power 5.5x2.1mm center positive barrel jack
