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.

Они отлично работают. Немного больше, чем я ожидал, но хорошо подходит для проверки на хлебных досках.

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

Small downstepper, very easy to use. Stable voltage. Great product for the price.

I've used similar items before and they work well. They arrived sealed in static protected bags. I have not tested them yet but they seem to be well made.
