  • Blue LED voltmeter

    posted by Nenetoo

    quite accurate with their information, the blue color is very beautiful and fresh gives a very different view, small model fits in any corner, got some pressure on the side to ensure the best wood to fix or put in any other corner you have to stay hidden, the LEDs are quite strong and its disign is very Bonico the details with black plastic.
    Great for car audio car because you have precise control of the battery so you do not lose the quality of power from your battery to your car stereo enjoyed without problem, the price of voltmeter be very good as was the fact that I found, recommend, great buy!

  • simple to use digital voltmeter

    Compact size, no backlight required because of LEDs display, just two wires to connect (powered by the same battery you measure). Wide range of input voltage.
    The power circuit has a protection against the reversed voltage (a diode in series of an IC voltage regulator) which is good but increases the lowest voltage you could measure.
    It's a great companion to battery chargers where you don't see any voltage information. Good module for DIY projects. The price could be lower because you can buy some simple multimeter for the same money.
  • Good instrument!

    Very good indicator of voltage. The size of the numbers is perfect to be placed on a dashboard. The making power at the same voltage to be measured. Very convenient! It is very easy to use, just connect the wires.
    Good buy if you want to know the current that delivers a power source. Ideal to build a dashboard. For the price you can take advantage!
    Nothing to add. Really is a great buy you will not regret making. It will be money well spent.
  • Great Voltmeter!

    Small boardVery good solder -high quality surface mounted, I was amazed really!Useful range (4.5 - 30V is more than I will ever use)No additional power source needed.Low power consumption.There is a trimpot, and you can calibrate it when needed.PCB is very small, but you have two mounting holes on edges!
    You can use it in in many many DIY projects, will fit anywhere!I am going to fix it to home emergency power supply unit.
    I recommend buying this Voltmeter.Will work as expected.

    pois é galera, o amperímetro funciono que é uma beleza no meu gerador hho, com precisão, o preço é ótimo em comparação com os que temos aqui no brasil, o acabamento também é muito bom
    só faltava ter um pwm caprichado nesse valor tambem. hiahaihaihaih
    vale a pena comprar, preço e qualidade.
