at the beginning I had some problems with this display, I could not get this to work. The reason of my problems was that I had the VCC pin at either 3.3V or 5V pin of the Arduino connected what was wrong. Because there is no reset pin, you have to the VCC pin to an I / O pin of the Arduino to connect and this then acts as a reset pin.
This Arduino OLED Library (github.com/adafruit/Adafruit_SSD1306) can operate the display good!
