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)

そんな小さなことで驚くほど働きます。 非常に小型で、ワイヤーはんだ付けが難しく、調整には1mmドライバーが必要です。 ただし、一度調整すると、入力レギュレーションが非常に良好になります(図参照)。8.90~14.50Vの入力では、出力の変化はわずか1mVです。入力が動作するためには、所望の出力より少なくとも1.5V以上でなければなりません。 3.30Vを正確にヒットしようとすると、3.3Vに調整することは、非常に便利です。 負荷調整や大電流でテストしていません。

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"

非常に小さなボードは、言葉と耐久性に真。 これは多くの異なるアプリケーションで使用できる優れたチップであり、それは小さいサイズで、これは勝者になります!

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!

非常に小さい調整可能なステップダウンモジュール。 充電可能なひげトリマーを、死んだNicadバッテリで改造したり、USB電源で動作したり、実際には5~23ボルトのDC電源で動作したりするのに使用しました。 安くて良い品質で、最大1.8Aの連続電流を必要としない限り、非常に使用可能です。

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.
