Feature:

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 it and the third wire is used for measurement. Simply connect the red wire to a positive power supply from 3.3VDC to 30VDC, 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 3.3V to 30VDC so it will be good for any electronic project! The meter draws 3-4mA to power the microcontroller and display. LED display is red , which we found very readable. Mounting tabs make this module easy to attach to any box or plate.
