It's a good habit to always check soldering points with cheap goods ordered from China. But be aware, in my order (see below) there is not one (!) that works correctly and some don't do anything at all. Oh excuse me, they do something, they destoyed an OLed display an GPS module and a BMP180. IAt first I blamed myself, things didn't work, well you start to check out things and only lastly these converters. I am not amused. As you can imagen. I am outright furious. And NO Banggood I am not goingto send you pictures. Why should I? I am not gettin back my modules.
Boa qualidade e preço

The goods were ordered on February 20, and arrived on April 4. I will try. Thank you seller.
It does exactly it said: can work changing 5V level and 3.3V level. I was impressed by its size.
Usefull for conecting 3.3V sensor to arduino boards.
Fácil de usar. Funciona bem.
Recebido conforme esperado, ainda não testado, mas estes módulos foram usados com freqüência para i2c, onewire e ws2812, mas ruim para serial normal em esp8266
circuito simples que faz o que deve.
