0.91 inch OLED display module with 128×32 resolution, an SSD1306 driver, and a four-pin I2C interface. Available in white or blue versions, it supports 3.3–5 V DC power for compact instrument readouts and device status displays.

This 0.91 inch OLED display module uses an SSD1306 driver and a 128×32 pixel matrix to present text, symbols, and simple graphics. Its narrow rectangular screen is suitable for compact status displays and instrument readouts. White and blue display versions are offered as separate monochrome options.

The module connects through a four-pin I2C interface with GND, VCC, SCL, and SDA connections.
