The 5V/3.3V Breadboard DC-DC Power Supply allows you to easily power your breadboard or any other circuit with a smooth regulated 5V or 3.3V supply. It uses a MC34063A DC-DC converter chip for high efficiency and a wide range of input voltage tolerance.

Features:

• DC-DC converter with high efficiency
• Wide input voltage 7V to 35V
• Jumper to switch between 5V or 3.3V output
• Plugs directly into a breadboard's power rails
• Up to 1A output (*)

NOTE: The board is supplied with a 0.5A fuse. To use the board with more than 0.5A load, remove the fuse and replace by a larger fuse, or bridge the two pins.
