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.

It does exactly it said: can work changing 5V level and 3.3V level. I was impressed by its size.

Recibido como se esperaba, aún no probado, pero se han utilizado estos módulos a menudo para i2c, onewire y ws2812, pero malo para el serial normal en esp8266

Received as expected, untested yet, but have used these modules often for i2c, onewire and ws2812, but bad for normal serial on esp8266
