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, SSD1306 can communicate in multiple ways including I2C, SPI and 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.
