Ordered 5 got 7 :-) Thank you very much for the premature Christmas gift! The only thing, I have to criticize is that both outputs are labeled "OUT -" (see picture)

Funktioniert erstaunlich für so eine kleine Sache. Es ist so klein, es ist schwierig, Drähte zu löten und man braucht einen 1mm Schraubendreher zum Verstellen. Aber einmal eingestellt hat es eine sehr gute Eingangsregelung (siehe Bilder). Von 8.90 bis 14.50V ändert sich der Ausgang nur 1mV! Der Eingang muss mindestens 1.5V über dem gewünschten Ausgang liegen, damit er funktioniert. Einstellen auf 3.3V ist sehr empfindlich, wenn man versucht, 3.30V genau zu treffen. Ich habe es noch nicht auf Belastungsregulierung oder bei Hochstrom getestet.

Works amazingly for such a small thing. It is so small, it is difficult to solder wires and you need a 1mm screwdriver to adjust. However, once adjusted it has very good input regulation ( see images). From 8.90 to 14.50V input the output changes only 1mV! The input must be at least 1.5V above the desired output for it to work. Adjusting to 3.3V is very touchy if you try to hit 3.30V exactly. I have not tested it for loads regulation or at high current yet.

After studying pictures & checking mp2307 datasheet i decided to buy them because pin 7 is enable pin connected via 100K (easily modifiable). See my picture [if BG has placed it] for a simulated low-drop 4-pin regulator. Now the item itself....... Packed in antistatic bags and very small. Pot-meter is too small so also too sensitive. A small bump might shift it several volts and destroy something. I recommend removing the pot-meter and use a [calculated] fixed resistor. But 1st check on-board resistors as "R2" is 8.2K (in my shipment) not 10K as in reference design from datasheet. So for 5V you need 36124 ohm. Recommended if you are willing to remove the pot-meter. Enable pin also usable. Most important though, fixed a DVD-TV combo with it.

Modulo Step Down Tensione in ingresso: DC da minimo 4.75V a massimo 23V Tensione di uscita: DC da 1.0V a massimo 17V regolabile tramite la piccola vite. Molto utile per piccoli progetti di modellismo e tanto altro.

Bought several of these for some micro LED arrays for a model railway. Stays cool under load, adjustment is a little tricky but with a small homemade turner glued on to the adjuster it was fine. Word of advice - The underside has power 'in' & 'out' marked for a reason..!

Very good, excellent quality, soon I will record a test video and set up on my Youtube channel, "Um Nerd Vintage"

Sehr kleines Brett wortgetreu und langlebig. Erhitzt nicht viel dies ist ein ausgezeichneter Chip, der in vielen verschiedenen Anwendungen verwendet werden kann, es ist winzige Größe macht dies zu einem Gewinner!

Very small board true to it's word and durable. Does not heat up much this is an excellent chip that can be used in many different applications, it's tiny size makes this a winner!

Große einstellbare Step-Down-Module, die recht klein sind. Ich habe ein, um meine wiederaufladbaren Barttrimmer mit toten Nicad Batterien zu modifizieren, um mit USB-Strom zu arbeiten, oder in der Tat, jede DC-Stromquelle zwischen 5 und 23 Volt. Günstige und gute Qualität und sehr brauchbar, solange Sie nicht mehr als max 1,8 A Dauerstrom benötigen.

Great Adjustable Step-Down Modules that are quite small. I used one to modify my rechargeable beard trimmer with dead Nicad batteries, to work with USB power, or in fact, any DC power source between 5 and 23 Volts. Cheap and good quality and very usable as long as you do not need more than max 1.8 Amp continuous current.

Ich benutze es schon lange. Gute Qualität, die Werkbank lässt sich nicht entgehen. Besuchen Sie meinen YouTube-Kanal FlyerFpv.

Já utilizo a bastante tempo. Boa qualidade, não pode faltar na bancada de trabalho. Visita o meu canal do YouTube, FlyerFpv.
