This Breadboard Power Supply is your solution to powering your 3.3V and 5V breadboard electronics projects for quick and easy prototyping as well as circuit building. Power your projects by plugging in any standard DC Wall Adapter with a voltage between 6.5V and 12V such as our 9V Wall Power Adapter. The Power Supply Module will then convert the 9V into 3.3V or 5V and output it into each side of  your breadboard, giving power to your breadboard rails (the blue and red strips at the edge of the breadboard labelled + and -). Move the Black jumpers up or down to select whether you'd like 5V or 3.3V on the left and right rails of your breadboard. The LED indicator will light up when your power is on. Use the onboard button to turn your power supply on/off.


  • Use a mini USB cable to supply power or a power adapter to power your breadboard projects!
  • Input Ports:
  • Outputs (to breadboard): 
    • Selectable GND, 3.3V, 5.5V DC (these outputs will be on the Blue and Red rails at the edges of your breadboard labelled + and -)
  • LED Power Indicator
  • 2 sets of Jumpers (used to select 5V, OFF, or 3.3V as the output on the left & right breadboard rails)
  • Small form factor
  • Max Current: 700mA
  • Arduino and Raspberry Pi Compatible (Select 5V for Arduino and 3.3V for Raspberry Pi)
