2 Wire Voltmeter display Module

This is a very small 0.36" Display Digital voltmeter. It can be used to measure DC voltages ranging from 3.3 volts to 28 volts.

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

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 3-4mA to power the microc-ontroller and display. This particular LED display is a nice vivid red, which we found very readable. Mounting tabs make this module easy to attach to any box or plate.
