    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.

    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.

    I've been using it for a long time. Good quality, can't miss the workbench. Visit my YouTube channel, FlyerFpv.

    Video de funcionamiento mas abajo. 5 unidades de una fuente paso bajo muy potente y equilibrada. No tiene fallos,muy sensible. No tiene calentamiento al trabajar a 2 amperios Con tres amperios hay riesgo de estropearse. 100% compra recomendada.

    Дошло быстро. Упаковано выше всяких похвал. Пока не ставил, но проверил со статичной нагрузкой - работают исправно. Очень компактные!

    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)
