I am looking for a compact solution to convert some 220V/20amp AC to something edible by our arduinos (like 5V/2amp DC). I would like to plug directly my arduino to the wall. I found many things like some Hi-link (HLK-PM01) chips ... But I also found this one :
That seems perfect, but unfortunatly, I can not find any tuto or example of use for this, shipping included, really cheap chip.
The datasheet is here.
What do you think about it ?
