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

Introducing a miniature yet highly readable OLED display, measuring just about 1 inch diagonally. Despite its small size, the high contrast of the 128x32 white OLED pixels ensures excellent visibility, and since the display generates its own light, there's no need for a backlight. This makes the display both energy-efficient and crisp, delivering vibrant visuals even in low power scenarios.

Key Features:

• 128x32 White OLED Pixels: Each pixel can be individually controlled, providing sharp, clear text and graphics.
• No Backlight Needed: Since OLED pixels emit their own light, the display doesn't require a backlight, which enhances contrast and reduces power consumption.
• Compact Size: Approximately 1" diagonal, making it ideal for space-limited projects.

Easy Integration:

• The OLED is pre-mounted on a breakout PCB, featuring necessary support circuitry to work with both 3.3V (Feather/Raspberry Pi) and 5V (Arduino/Metro328) logic levels.
• Auto-reset Circuitry: The display includes auto-reset functionality, making the reset pin optional, simplifying the setup.
• I2C Interface: Connects easily with just two wires for communication (plus power and ground).
• Includes STEMMA QT connectors for easy plug-and-play integration with I2C, eliminating the need for soldering. Just use a STEMMA QT adapter cable to hook up to your microcontroller (cable not included, but available in the shop).

Usage and Power:

• Power Consumption: Typically uses around 20mA from a 3.3V supply, depending on how much of the display is lit.
• Built-in Charge Pump: The OLED driver includes a switch-cap charge pump, allowing the display to run on a 3.3V to 5V supply, making it very easy to integrate into your project.

Software Support:

• We provide detailed tutorials for both Arduino and Python/CircuitPython libraries for handling text and graphics on the display.
• A microcontroller with at least 512 bytes of RAM is required to buffer the display.

Important Notes:

• OLED displays use organic LEDs for each pixel. If a pixel is kept on for too long (over 1000 hours), it may start to dim. To maintain uniform brightness, turn off the display when not in use, or set the pixels to off when possible.

This compact OLED display is a fantastic choice for anyone looking to add crisp, energy-efficient visuals to their project with minimal hassle
