good package, I will test it later

prós: - compacto - barato - extremamente útil para projetos com microcontroladores cons: - não tem marcação indicando modelo, tem que prestar atenção para não misturar com a fonte de 5v

Ricevuto nei tempi previsti. Oggetto conforme a quanto descritto. Non ho ancora avuto modo di testarlo ma ritengo che ci sia un ottimo rapporto qualità/prezzo.

Didn't test it yet, but it seems OK.

OK, but it lacks the detail of the volts dispensed... a bit uncomfortable having to use the tester (I took it as a spare so it will be archived)

ok, ma manca il dettaglio dei volt erogati... un po’ scomodo dover usare il tester (lo ho preso di scorta quindi andrà archiviato)

Items are as described. There is neither sign nor marker on the shell to identify wires of input and output. We connect it to high voltage, so 110-220V AC input should be marked. There is a small sticker with hand written "3.3V" sign to distinguish 3.3V version and 5V version. I ordered both type from this seller. This sign is very appreciated! I found that red and red wire pair is input, these wires should be connect to 110-220V. black and red wire pair is output. If you are not sure, just open shell and check electronic parts. Be aware that PCB is fixed into box some glue. In my case component side of PCB was visible. I have not tested it yet.

These are very tiny modules but they really work well. Although I have 240VAC supply I tested them from 110 to 250VAC and it was as steady as a rock. One tip: they like a load to work well. I found from 20mA the supply was rock solid. This is not an unusual characteristic.

Good product, does the job and is more than enough for me. I use it to power a microcontroller.

Bon produit, fait le travail et me suffit largement. Je l'utilise pour alimenter un micro-controlleur.
