SparkFun Breadboard Power Supply Stick - 5V/3.3V

The SparkFun Breadboard Power Supply Stick is a compact and versatile power solution for your breadboarding projects. It accepts an input voltage of 6-12V and delivers a regulated output of either 5V or 3.3V. The headers have a pitch of 2.54mm, making them perfect for easy insertion into a breadboard. Power can be supplied via a DC barrel jack or a 2-pin header, and output is provided through the GND and VCC pins. The board features both an On/Off switch and a voltage select switch. The holes for GND and VCC are spaced to power both busses when connected to a basic breadboard.The SparkFun Breadboard Power Supply Stick is an excellent tool for powering your breadboard-based electronic circuits. Whether you're prototyping a new design or experimenting with different components, this power supply stick ensures a steady and reliable power source. Its selectable output voltage makes it compatible with a wide range of components, from low-power sensors to high-performance microcontrollers.One of the standout features of this power supply stick is its simplicity. Its design is straightforward, making it easy to connect and use. The On/Off and voltage select switches add flexibility and control, allowing you to adjust the power supply to your specific needs. The power status LED provides a quick visual indication of the power supply status.This power supply stick is also designed with safety in mind. It includes a PTC fuse for power protection, guarding your precious components from any power surges. Please note that headers are not included, and you will need to supply your own to connect this board to a breadboard.Key Features:
