SparkFun Breadboard Power Supply 5V/3.3V

SparkFun Breadboard Power Supply 5V/3.3V is a simple and effective solution for powering your breadboard projects. This kit takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The 2.54mm headers are mounted on the bottom of the PCB, enabling easy insertion into a breadboard. With VCC and GND pins that plug directly into the power lines, and a pair of support pins, this power supply is designed for convenience and stability.

The SparkFun Breadboard Power Supply also features two pins within the barrel jack footprint. This allows you to connect any stripped +/- DC supply in place of the barrel connector. The board is equipped with both an On/Off switch and a voltage select switch (3.3V/5V), providing you with control and flexibility in your projects.

This product comes as a bag of parts kit that can be easily assembled by anyone with basic soldering skills and the ability to read resistor bands or use a multimeter to determine resistor sizes.

The kit includes a variety of components such as a DC Barrel Connector, TO-220 Voltage Regulator, 1N4004 Reverse Protection Diode, capacitors of varying sizes, a high brightness Red Power LED, SPDT Slide Switch, header pins, resistors, a bare PCB with silkscreen indicators, and a PTC resettable fuse.

With a compact size of 3.175cm x 3.175cm, the SparkFun Breadboard Power Supply is perfect for any project, big or small. Whether you're a hobbyist, student, or professional, this power supply kit is a valuable addition to your toolkit.
