Hi again,

do you have a technical description, data-sheet or any detailed instructions? What exactly does each of the two resistors? Which resistor must have a higher or lower value (and what range: Rmin / Rmax ) to increase or decrease the output voltage? can I use a potentiometer and how has it to be connected? I don’t ant to destroy the converter by using the “try-and-error” method.

Without these informations the dc-dc-converter may be a nice piece of technique, but whole potential can never be exhausted by the user. The typical buyer isn’t willing to inspect the circuit and do a reverse engineering to find out how he can take the full use of the converter. The same applies to me.

If you would provide a PDF-file with all these informations (including a circuit diagram) for download you could sell much more of the dc-dc-converter (and all other devices) and you would have avoided the negative comment on Amazon.de. No, it wasn’t me 😉

What size SMD is the resistor?

0402
0603
0805
1206

I need to know which physical size to purchase.

Hi, good day!

Is it possible to obtain a datasheet for this product?

Kind Regards,
Kevin
