A very simple breadboard power supply kit that takes power from a DC wall power supply 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 .
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.
