Mini 2-wire Volt Meter (3.2 - 30 VDC)

Mini 2-wire Volt Meter (3.2 - 30 VDC)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
