Adjustable Breadboard Power Supply Kit

A good power supply is essential to any electronic projects, and this adjustable breadboard power supply kit is ideal for making your own breadboard-friendly very low drop-out adjustable power supply. 

While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs.

The Adjustable Breadboard Power Supply Kit  Features:

  • MIC2941 regulator has guaranteed 1.25A output
  • Low dropout, only 40mV - 400mV compared to 1.25V - 2.0V for LM317. This means you can use a wider range of output voltages including generating 3.3V from as low as 3.7V (such as 3 AA's or a lithium ion battery)!
  • Short circuit and overheating protection
  • Input diode to protect circuitry from negative voltages or AC power supplies.
  • 2.1mm DC jack and terminal connector for voltage inputs
  • Two indicator LEDs for high and low voltages
  • Output selection switch to select from 3.3v, 5v and Adjustable
  • Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max)
  • On/Off switch for entire board
  • Heat sink included
  • Dimensions (PCB only): 54mm x 21mm x 1.6mm (2.1in x 0.8in x 0.06in)
  • Dimensions (Assembled): 54mm x 43mm x 16.6mm(2.1in x 1.7in x 0.6in)
  • Weight: 16g / 0.5oz
This project kit comes as components to be soldered to the included PCB. It's not a difficult project, about 30-45 minutes with a soldering iron. Even beginners can make it! You'll need a soldering iron, solder, diagonal cutters and a PCB holder such as a helping hand tool. Breadboard and battery clip or DC power supply is not included, you can use any DC power supply with 2.1mm plug (we have a nice one in the shop). Checkout the tutorial below on how to assemble and use the kit!
