Well, I made initial test (https://youtu.be/r63xqLkxc5Y ) and the module works fine. It is well assembled with good materials, has a good size and the module itself do what it has to do, adjusting output voltage of power supply with a very sensitive potentiometer. However, the onboard voltmeter connection is too weak and I broke it trying to figure out why it was not working (the voltmeter) . But how I am not pretending to use voltmeter as onboard feature, it does not matter. I can solder it with a pair of wires and everything is gonna be all right. Despite of incident, I'm very satisfied with product ! Thank you!

circuito funciona mas a posição do capacitor eletrolítico na frente do display prejudica a visão.
