Put a voltage meter anywhere with this very handy display. These are often used by RC hobbyists for keeping track of batteries but we thought it would be great on a breadboard or enclosure. This is the 2-wire version of the volt meter, two wires are used to power it and measure at the same time.

Simply connect the red wire to the positive supply, and black to negative ground. The display has a microcontroller that will read the voltage, compare it to a stable reference and display the voltage with 0.1V precision on a 3-digit 7-segment display. It works from 3.2V up to 30V so it will be good for nearly any electronic project! The meter draws <13mA to power the microcontroller and display. Mounting tabs make this module easy to attach to any box or plate.

Note: We also have a 3-wire version that measure a wider range of voltages.

Features:

  • 3.2V to 30V DC measurements (positive voltages only)
  • 0.1V precision
  • Current consumption < 13mA
  • Refresh rate 300ms
  • Blue LED display
  • Reverse-polarity protection.

Dimensions:

  • PCB (with mounting holes): 33.4mm x 14.1mm
  • Display: 22.5mm x 14.1mm
  • Combined Depth: 10.5mm
  • Weight: 4.8g
