    Компактный вольтметр для DIY
    Color:Red
    Pros:
    Шикарный вольтметр. Маленький, яркий. С завода точно откалиброван. Есть ушки для крепления к корпусу и подстроечный резистор для точной установки показаний (используя лабораторный блок питания). Скорость изменения показаний достаточная. Не требует отдельного питания. При напряжении ниже 10 В точность 0,01 В, выше - 0,1 В.
    Cons:
    нужно придумывать защиту задней стороны от нежелательного контакта/ замыкания припаянных элементов.

    nice for projects above 3 volts
    Color:Green
    Pros:
    Very nice for testing li-ion battery's.
    Nice for bread board testing.
    Works well above 2.5 volts, below 2.5 no or limited display. LEDs will not light on display. Being the display is driven by the test source makes it load battery's and test volts properly.
    Adding a capacitor in line with the meter can change the display voltage if the cap is not part of the load.
    Cons:
    Easy to use but the driver board can die without warning or cause this may be cured with a inline diode to prevent voltage spikes.
    Not all read the same voltage exactly but are close.
    Cheep, easy to use, great for voltage indication in battery charging of cars.
    I purchased 10 pieces and one died with In a week and one more died while bread boarding use and 7 more are in my project's.

    Great voltmeter for custom projects
    Color:Green
    Pros:
    - easy to install. Just two wires to connect and it shows you the voltage.
    - good build quality
    - bright display, not flickering
    - can be fine tuned to achieve higher accuracy
    I used this voltmeter in my mod of the Lii-100 (see pictures).
    Cons:
    - support for lower voltage down to 1V would be nice but is probably not possible(?)
