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"

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

Customer Comments

  • Any specs on how much current or power this can supply? Voltage alone is only half the equation. ;-)

    • The regulator on board is rated to a max of 800mA.

      • Need to be careful here - the 800mA Operating Current listed is misleading if not put into context.

        Only the regulator IC (LD1117) is rated at 800mA. The total amount of current this board can supply is dependent on several factors, most importantly, the total power required (Watts, based on Vin, Vout, Iout), and the ambient temperature.
