Mini 3-wire Volt Meter (0 - 99.9VDC), Green 3 Digit DisplayPut 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 is used for measurement. Simply connect the red wire to a positive power supply from 4. 5 to 28VDC, and brown or black to the common ground to power the display.
