Panel Volt Meter - 4.5V to 30VDC Category_Microcontrollers/Particle All you need to knowPut 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! 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 0. 56" tall 7 segment display. It works from 4. 5V up to 30V and
