SparkFun Qwiic OLED Display (0.91 in, 128x32)

The SparkFun Qwiic OLED Display can display up to three lines of text and features 128x32 pixels in a small 0.91” (diagonal) frame. As an OLED, this display does not have a back light layer (unlike LCDs) and therefore it’s thinner, consumes less power, and has higher contrast.

Thanks to an I2C command structure, the board's firmware maintains speed by updating only the part of the screen that changes This is the same concept use with "Dirty Rectangles" or "Bit blit" operations in computer graphics.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
