SparkFun Breadboard Power Supply Kit, USB to 3.3V

The SparkFun Breadboard Power Supply Kit is a simple yet efficient solution for providing a regulated and fuse-protected 3.3V output. Powered via a USB 2.0 port, this kit is ideal for prototyping and electronics projects, ensuring a stable power supply for your circuits.

Key features include 0.1-inch headers mounted on the bottom for easy insertion into a breadboard, allowing for seamless integration into your setup. The board can be oriented sideways, enabling simultaneous access to both 5V and 3.3V outputs—perfect for diverse project requirements.

Safety is ensured with an on-board 500mA PTC fuse, protecting your components from overcurrent. A convenient on/off switch allows for quick power management, adding an extra layer of control during testing and development.

Assembly Required: This kit comes as a bag of parts, so you'll need to assemble it by following the silkscreen indicators on the PCB. Included components are:

• PCB
• USB B port connector
• Voltage regulator
• PTC fuse
• LED
• Power switch
• Capacitors (0.1uF 50V, 10uF 25V, 100uF 35V)
• Resistors (240Ω, 330Ω, 390Ω)
• Header pins

Warning: Be cautious of unused power and ground pins, as they may short if inserted into a breadboard row. To avoid this, position the board so that unused power pins hang off the side.

Compact and practical, this power supply kit is a must-have for electronics enthusiasts and professionals alike, offering reliability and flexibility for a wide range of applications.
