- Mini Panel Mount Digital Voltmeter 0-99.9VDC
Product Description
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 3-wire version of the volt meter, two wires are used to power it and the third wire (yellow) is used for measurement.
Simply connect the red wire to a positive power supply from 4.5 to 28VDC, and black to the common ground to power the display. Finally, connect the yellow wire to whatever you want to measure the voltage of. 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 can read from 0V to 99.9VDC so it will be good for any electronic project! The meter draws 3-4mA to power the microcontroller and display. This particular LED display is red.
