Product Description

This is a simple 3-digit LCD display of voltage.


To use it, first hookup the power voltage (between 3.3 and 30 volts) to the red (+) and black wires, with black as ground (-).

Then, hookup your input voltage that you wish to measure to the yellow/white and black wires. If you wish to measure the voltage that is powering the device, simply twist the red and yellow/white leads together.
