    Quantity:

    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.

    Features:

    • 4-9V input voltage via barrel jack or 2-pin header
    • 3.3V or 1.8V 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
    • 2.15x0.65"
