Monochrome OLED Graphic Display – I2C

Monochrome OLED Graphic Display – I2C

This tiny, bright, and perfectly readable Adafruit OLED display is a fantastic addition to any project.

• The display consists of 128×32 white OLED pixels and requires no backlight, as it emits its own light, providing excellent high-contrast visibility.
• The driver chip communicates exclusively via I2C. Only 3 pins are required to interface with the display (2 of which are I2C data/clock pins).
• A built-in 3.3V regulator and level shifter make the display compatible with all 5V logic controllers.
• Power consumption depends partly on how much of the display is lit, but it typically averages around 20mA from a 3.3V supply.
• The OLED driver has a simple switched-capacitor charge pump. It converts 3.3V–5V into a high-voltage drive when using OLEDs. This makes it one of the easiest ways to integrate an OLED into your project.

Please refer to the Adafruit OLED tutorial and Arduino library with examples for more information.

A microcontroller with more than 512 bytes of RAM is required because the display uses a framebuffer. However, it remains very fast in operation.
