Monochrome 0.91" 128x32 I2C OLED Display - STEMMA QT / Qwiic

These compact monochrome OLED displays are about 0.91" diagonal with a resolution of 128x32 pixels, offering very high contrast and readability with white pixels that turn on or off via the controller chip. The display is self-illuminating, requiring no backlight, which significantly reduces power consumption while delivering crisp text and graphics.

This module operates with 3.3V or 5V logic levels and includes support circuitry on a breakout PCB, making it compatible with Feather, Raspberry Pi, Arduino, and Metro328 boards. The updated design features auto-reset circuitry making the reset pin optional. It uses an I2C interface and includes SparkFun Qwiic/STEMMA QT connectors for easy, solderless connections.

Key Features:

• 0.91" diagonal monochrome OLED display with 128x32 pixel resolution
