Monochrome 1.3" 128x64 OLED graphic display - STEMMA QT / Qwiic

This 1.3" diagonal OLED display offers exceptional readability thanks to its high contrast. It features 128x64 individual white OLED pixels, each controlled by a built-in driver chip. The self-illuminating nature of OLED technology eliminates the need for a backlight, resulting in reduced power consumption and enhanced contrast, making it ideal for compact, high-quality displays.

Key Features:

• Driver Chip: SSD1306, supports both I2C and SPI communication.
• Power Supply: Requires a 3.3V supply, with logic level compatibility for both 3V and 5V devices due to an included 3.3V regulator and level-shifting pins.
• Auto-reset Circuitry: Reset pin is optional, and the default interface is now I2C for simpler wiring (just two wires needed, along with power and ground).
• STEMMA QT Connectors: I2C connection is made easy with SparkFun qwiic compatible STEMMA QT connectors, eliminating the need for soldering. (QT cable not included, but available for purchase).
• Current Draw: Around 40mA on average from the 3.3V supply, depending on how much of the display is active. Includes a charge pump to drive the OLEDs efficiently.
• Tutorial & Code: Comes with a detailed tutorial and example code for Arduino and Python/CircuitPython, enabling easy display of text and graphics. Requires a microcontroller with over 1K of RAM to buffer the display.
• Display Capability: Can display text, bitmaps, pixels, rectangles, circles, and lines, utilizing 1K of RAM for fast performance.

Important Note: OLED pixels can dim after over 1000 hours of continuous use. To maintain uniform brightness, it's advised to turn off unused pixels when the display is not in use.

This updated OLED breakout board now features an improved design for easier plug-and-play usage, with added convenience for I2C communication. The default protocol has been switched to I2C, and two STEMMA QT/Qwiic connectors make the board easier to integrate with various devices. The auto-reset circuitry ensures that the display resets automatically on power-up. If you wish to use SPI mode, you can cut two jumpers, though I2C is now the default.
