Product work fine but it first showed unprecise voltage value but it can be calibrated (both input and output separately that is good point) Press left button to display input voltage, press right button for 3 secs, display go off, then release button, display will blink, then adjust using left/right buttons according to your voltmeter and press right button 3 seconds again to save. Now to calibrate output, press right button to show output voltage, press right button 3 secs... calibrate... press 3 secs again and that's it ! But I don't know what the blue variable potentiometer is used for ?

Очень качественная плата. Выполнена отлично. Все функции заявленные продавцом,работают. Вольтметр показывает достаточно точные значения с довольно хорошей реакцией. Можно замерять как входное так и выходное напряжение, а так же выключать вольтметр при необходимости. Очень удобные клеммные колодки, упрощают монтаж.

Can be used as a battery tester and I have already used it to quickly test a 3 volt bulb going into a headlight on an rc boat. I can see that it could be used as a step down in a rc boat or plane or heli where you are using a 11.1v or 7.4v supply and you want to install something that is only 3v or 6v and so need to reduce the voltage although this could be done using a resistor as well. WARNING - The voltage showing on the display is not accurate. It is out by around 0.5v to 0.6v so if you have something that needs an accurate voltage then the use of a voltmeter on the outgoing side is crucial but in most applications half a volt will not matter. Definitely a must have and a very good price.... Delivered very quickly within 4 days from the UK Warehouse to my UK address Thanks Steve D

Stable stepdown converter income voltage reading and outgoing reading, it works great!

A litlle sceptical at first buying electronics from here, but i powered this up when i got it and it works a treat. Easy to use and great value for money.

يبدو جيداً، لم تسنح لي الفرصة لإستخدامه في الوقت المناسب.

Looks good , haven't had a chance to use it came in on time.
