New in the Maker Shed: Mini Volt Meter

The Maker Shed’s new Mini Volt Meter is super handy for keeping your eye on voltages. It was originally intended for use in RC vehicles but works great with robots, breadboards, or other projects. The vivid green 3-digit 7-segment display accurately reads voltages from 3.2v – 30v with 0.1V precision. The small size allows you to fit it almost anywhere.


  • PCB: 30mm x 20mm
  • Display: 23mm x 14mm
  • Combined Depth: 11mm
  • Weight: 5.45g

Power specifications:

  • 3.2V to 30V DC measurements
  • 0.1V precision
  • 3-4mA draw
  • Green LED display
  • Use with positive voltages only!

I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I'm a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.
