An interesting device to power the 3.3 volt electronics. I use it to power arduino pro mini and esp8266 and other sensors and radios that operate at 3.3 volts. Being a switched regulator it has a high conversion efficiency from 5 volts or more and is suitable for use with batteries. I bought 10 units but they only sent me 5 units. The announcement and in the package I received put 10 units but there were only 5 units. I hope Banggood will solve it.

Ça marche très bien. Un peu plus grand que ce à quoi je m 'attendais, mais bon pour les tests sur des planches à pain.

These work great. A little bigger than I was expecting but good for testing on breadboards.
