SparkFun Qwiic OLED Display (0.91 in., 128x32)

The SparkFun Qwiic OLED Display showcases up to four lines of text with a resolution of 128x32 pixels in a compact 0.91-inch (diagonal) frame. This OLED display is thinner, consumes less power, and offers higher contrast compared to traditional LCDs, as it lacks a backlight layer.

Utilizing an I²C command structure, the board's firmware enhances speed by updating only the screen sections that change, similar to "Dirty Rectangles" or "Bit blit" operations used in computer graphics.

This iteration of the Qwiic OLED display features two vertical Qwiic connectors on the back, facilitating easy mounting and wire management within enclosures. The mounting holes are now positioned on one side of the board for streamlined installation.

The SparkFun Qwiic Connect System is a versatile ecosystem of I²C sensors, actuators, shields, and cables designed to accelerate prototyping and reduce errors. All Qwiic-enabled boards utilize a standardized 1mm pitch, 4-pin JST connector, minimizing PCB space requirements and ensuring polarized connections to prevent incorrect hookups.
