Collected perfectly, the rest of the flux is not observed. The conclusions are signed, though the jumper modes are signed in chinese. Otherwise everything is fine, the main thing that would work. As i check, i will add a review. Shipping is not fast (free)))

Entertaining thing, the speed of flicker leds is customizable

I ordered two pieces, both work properly! The specified voltage is kept confident. To adjust the output voltage, you need to twist the potentiometer counterclockwise. In my case, both were at the maximum, twisted quite a lot-about 10 revolutions, only after that began to put the voltage.
