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.
