Overview<\/strong><\/h4>\n

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, so that the pins labeled VCC and GND are plugged directly into the power lines. The lone pair of pins have no electrical connection but help to support the PCB.<\/p>\n

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 (3.3 V \/ 5 V).<\/p>\n

It is versatile and fits most of the breadboards. You can use it to power your custom microcontroller projects, or as an auxiliary supply for the 3.3 V sensors from your Arduino projects.<\/p>\n
