    Компактный вольтметр для DIY
    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.
    Suggestion
    нужно придумывать защиту задней стороны от нежелательного контакта/ замыкания припаянных элементов.

    Šikovný voltmetr pro zabudování
    Perfektní velikost, výběr barev, dobré zpracování. Dostatečná délka přívodních vodičů, možnost připevnit šroubky do panelu. Modul je vhodný pro sledování napětí v automobilu, u napájecích zdrojů atd. Zabudoval jsem do nabíječky Liitokala Lii-100 koupené na gearbest. Dvojitý přepínač pro nastavení vstupu pro akumulátor a USB. Monitoring napětí akumulátoru, monitoring výstupního napětí 5 voltů jako powerbanka. Super cena, rychlé doručení. Děkuji.

    nice for projects above 3 volts
    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.
    Suggestion
    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
    - 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).
    Suggestion
    - support for lower voltage down to 1V would be nice but is probably not possible(?)

    DC Voltmeter Module
    The product, cheap, solidly constructed, is no different from the products of popular manufacturers. We would recommend the purchase of this product just because it is doing great. It is small and shows accurate results.

    Perfect, as described!
    The display works very well with very good precision. I've ordered 3 displays and they measure correctly the voltage compared with a multimeter without any error.
    Turn on starting from 2,5V. Small and bright
    Perfect :)
    Suggestion
    Nothing

    Nice voltmeters
    Wide voltage from 4V to 30V. Accuracy is good and can be adjusted. No seperate power supply needed. I use it to monitor the voltage of acid lead batteries used with UPS.
    Suggestion
    None
