This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

The driver chip,&nbsp; **SSD1306** &nbsp;can communicate in multiple ways including&nbsp; **I2C** ,&nbsp; **SPI** &nbsp;and&nbsp; **8-bit parallel**. However, only the 128x64 display has all these interfaces available. For the 128x32 OLED, only SPI is available. Frankly, we prefer SPI since its the most flexible and uses a small number of I/O pins so our example code and wiring diagram will use that.

For the 0.96" STEMMA QT version, **we've updated the design to add auto-reset circuitry** so that the reset pin is optional, since it speaks I2C you can easily connect it up with just two wires (plus power and ground!).&nbsp; We've even included [SparkFun qwiic](https://www.sparkfun.com/qwiic) compatible**&nbsp;[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt)**&nbsp;connectors for the I2C bus so **you don't even need to solder!** &nbsp;
