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)

Ça marche incroyablement pour une si petite chose. Il est si petit, il est difficile de souder des fils et vous avez besoin d'un tournevis de 1mm pour régler. Cependant, une fois ajusté, il a une très bonne régulation d'entrée (voir images). De 8.90 à 14.50V d'entrée la sortie change seulement 1mV! L'entrée doit être d'au moins 1,5 V au-dessus de la sortie désirée pour qu'elle fonctionne. S'ajuster à 3.3V est très délicat si vous essayez d'atteindre 3.30V exactement. Je ne l'ai pas encore testé pour la régulation des charges ou à courant élevé.

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"

Très petite planche fidèle à son mot et durable. Ne chauffe pas beaucoup c'est une excellente puce qui peut être utilisée dans de nombreuses applications différentes, sa taille minuscule en fait un gagnant!

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!

Grands modules de descente réglables qui sont assez petits. j'en ai utilisé un pour modifier mon trimmer barbe rechargeable avec des piles Nicad mortes, pour travailler avec l'alimentation USB, ou en fait, n'importe quelle source d'alimentation CC entre 5 et 23 Volts. Pas cher et de bonne qualité et très utilisable tant que vous n'avez pas besoin de plus de max 1.8 Amp courant continu.

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.
