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.

Łatwy w użyciu. Działa dobrze.

easy to use. works well.

Otrzymane zgodnie z oczekiwaniami, jeszcze nieprzetestowane, ale często używane te moduły dla i2c, onewire i ws2812, ale złe dla normalnego seryjnych na esp8266

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

Prosty obwód, który robi to, co powinien.

Simple circuit that does what it should.
