This kit is for making your own breadboard-friendly very low dropout adjustable power supply. A good power supply is essential to electronic projects. While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs
  • 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


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).

Small, neat and really useful

This was just what I needed to provide extra power for both Raspberry Pi and Arduino projects. The instructions on the project webpage are excellent - easy to follow descriptions and large photographs. It is very simple to solder. Once built it provides 3

Don't go breadboarding without one...
Tuesday, 4 September 2012  |  Duncan

If you do any breadboarding with split voltage-rails this is an absolute must have - simply the best thing I've plugged into a breadboard since an Arduino...
