Available in red, green or blue, these little LED voltmeters are the quick and easy way to add voltage readout at various points in your project.
Unlike our AD448 two wire voltmeter, this meter has a third wire for the measured voltage allowing for a greater range of measurement.
Just connect the red to wire positive and black wire to negative to power the meter and then connect the yellow wire to the power source
you want to measure, that's it!
Great for monitoring voltages during development and debug or as a permanent part of the project.
