Yizhet 10 Pack Buck Converter DC to DC, High Efficiency Voltage Regulator, 3.0-40V to 1.5-35V, Adjustable Power Supply Module

I've used one of these to drive a Raspberry Pico and a multicoloured ring to light up a small fountain, connected to a 12v supply. I installed both AC and DC in my garden many years ago - forward thinking :). It's been running my Pico (and LED ring) quite nicely at the correct voltage (and current).Note: To get to the correct voltage, I did initially have to turn the pot quite a few times, it then started to change, and then it was quite sensitive, but all good and very impressed.All housed in a waterproof box.

Yes very pleased and good value for money.

Initially thought these were faulty because the output voltage wasn’t changing with the screw adjustment. Turns out that you have to screw the adjuster in a lot before the voltage starts to drop. Once the voltage starts changing the adjustment is ok.

Tested two of a pack of five. used a range of input voltages from 5 to 20. Output was consistently 0.7v lower than input. No adjustment to output voltage was possible.

Very easy to use, easy to accurately set the output voltage using the multi-turn pot on the board.I like the wide range of input voltage too, makes the items far more versatile for my needs.The item has proved to be entirely stable to date.Happy with them.

You get 5 of them for £7 which I'd great value, plus they felt surprisingly high quality and well made.

Nice and compact just what I need to drop voltage down from 24 V down to 12 V for my project Drawing no more than 2 A.

Got the pack of 5 and the first one I fitted was a dud, did not adjust the voltage at all.Hopefully the rest are better .

Works good. Good for tinkering, but would appreciate screw terminals instead of having to solder wires to it.

Ottimo ed efficace regolatore di tensione DC, dimensioni molto compatte. Con un piccolo cacciavite è possibile regolare la tensione in uscita da 1,2 a 35 V. Voto 9

Für verschiedene Projekte wurden die Schaltungen benötigt. Meist wurde von alten Akkutypen auf neue Art umgestellt. Da stimmten dann die Spannungen nicht mehr und mussten angepasst werden. Klein, leicht und leistungsfähig!

Conforme à mes attentes.

Es Funktioniert so wie es soll.Es ist nur wichtig wenn man z.b. nur mit 9V reingeht und mit 5V raus möchte muss man sehr lange gegen den Uhrzeigersinn drehen bis was passiert.Wenn Man den Dreh raus hat funktionieren sie super.
