    It works as expected. I power it from my solorpanel and I can regulate the output voltage. The potentiometer is not linear as expected, because usable angle is low. The con is only this potentiometer, feels cheap, but for that price cannot expect more as in my country LM317 costs almost the price of the whole device.

    Adjustable voltage regulators are really easy to do with components you probably have laying around... but for this price I would recommend you to buy this little module. You might save some time for other parts of your project. Works fine!

    Very affordable and of great use. Much better to buy from Banggood direct given that that the local suppliers also import from China but do not pass the saving onto the customer.

    Silkscreen error in component side of PCB may cause board to not function at all. Polarities of D3 and D4 must be reversed.
