The 5V Breadboard Power Supply allows you to easily power your breadboard or any other circuit with a smooth regulated 5V supply. Power it using a standard 9V wall wart with a 2.1" barrel connector.

It's made to be attached directly to the power rails on your breadboard. The compact size also makes it a perfect candidate for building in to any finished product that requires a regulated 5V power supply.


  • Attaches directly to breadboard power rails
  • PTC fuse to protect from short-circuits and from drawing too much power
  • Protection diodes to protect from incorrect polarity
  • Power LED
  • 7805 regulator with smoothing capacitors (data sheet, L7805CV)
  • Compact PCB with easy to solder through-the-hole components
