A good Step Down module, that can regulate Voltage and Current. Not the first time I use this product. Notice that the functions of the pot are not indicated on the board. With a voltmeter it's easy to see which one is for voltage and which one for current. Be careful, mine has one power transistor isolation pad not really fully covering the heating. The screws were not tide too. I will recommand a little inspection before use. The two 10 kohms pots can be replaced by external one if you need.

... It does what the product description promises. It's not the first one I use. ..the quality of the materials could have been better... But at this price, it's excellent. Quick mission!

... κάνει ότι υπόσχεται η περιγραφή του προϊόντος...δεν είναι το πρώτο που χρησιμοποιώ.... ..η ποιότητα των υλικών θα μπορούσε να ήταν καλύτερη... αλλά σ αυτή την τιμή είναι άριστη.. Γρήγορη αποστολή,!!

Incredibly small but very good! Order arrived without delay and without problems, nothing damaged and well packaged. I have already tested and was very pleased, I put in the entrance 22 Volts DC taken from my source and was regulating the output and took several voltages as you can see in the photos. So I recommend it, it didn't heat up and finally I say it's a good regulator from DC to DC. We must be careful not to exceed the maximum voltage allowed by the manufacturer. Thank you Banggood

Incrivelmente pequeno, mas muito bom! A encomenda chegou sem atrasos e sem problemas, nada danificado e bem embalado. Já testei e fiquei muito contente, coloquei na entrada 22 Volts DC retirados da minha fonte e foi regulando a saída e tirei várias voltagens como podem ver nas fotos. Por isso recomendo, não aqueceu e por fim digo que é um bom regulador de DC para DC. Temos que ter atenção em não ultrapassar a voltagem máxima permitida pelo fabricante. Obrigado Banggood

all seems good, one leg of a pentiometer have broke during travel, but I have replaced it and the modul works.
