SparkFun PRT-00114 Breadboard Power Supply 5V/3.3V

Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1″ headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines. The lone pair of pins have no electrical connection but help support the PCB.

There are two pins available within the barrel jack footprint. Any stripped +/- DC supply can be connected instead of the barrel connector. Board has both an On/Off switch and a voltage select switch (3.3V/5V).

Comes as a bag of parts kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

Dimensions: 1.25×1.25″

    Excellent unit and at the price it’s not worth buying the components and building one from scratch.Took on board the comments about the LED and fitted a normal intensity device saving the supplied LED for use as a searchlight should I ever need one.I al
