Amelyik nem hibás, az megfelelően működik. A potenciómétere egy kicsit silány minúségű, de ár érték arányban rendben van, csak kár hogy az egyik hibásan érkezett, nem lehet állítani a kimeneti feszültséget rajta.

Tested one piece out of five and it's working fine. But these circuits at lithium ion battery also works like a battery eater.

Bom produto, bom vendedor, boa loja! Recomendo!

Picked up a bunch of these for some projects I'm working on. The traces are nice and clean and there is no flux residue on them. Nice large traces for the power rails.

Trés peu d'ondulation, pas besoin de filtre, ideal pour toute sorte d'application. je le recommande.

Good product, well made, It works, the same as in the photographs in the shop. Thank you very much. I order the same thing.
