Digital Voltmeter DC 0-100V 3-Digits 0.28" Red-LED Mini Panel Meter

Put a voltage meter anywhere with this very handy display. This panel meter simply connects to whatever DC supply you are trying to track, easy to wire up!

The display has a microcontroller that will read the voltage, compare it to a stable reference and display the voltage on a 3-digit 7-segment display. It works from 4.5V up to 30V and is reverse-polarity protected so it will be good for nearly any electronic project! This particular LED display is a nice vivid red, which we found very readable.
