    I tested this small Volmeter with respect to my full scale one.
    It was accurate and very easy to use.
    I intend to put it on a DIY power supply from an ATX PS, to be used as a lab PS.

    It’s small, efficient and easy to watch. Pay attention to wires that are more rigid and can peel off.

    This little volt meter is great! It’s small, easy to connect, accurate, and very inexpensive. I have several and put them anywhere I need to know the voltage. This is a fine little sensor.

    Extremely useful for prototyping and in-circuit voltage monitoring and cheap enough to leave in. Using some for lipo battery voltage indicators.
