SparkFun Qwiic OLED Display

SparkFun Qwiic OLED Display is designed to display three lines of text and features 128×32 pixels in a small 0.91-inch (diagonal) frame. The display is thin, consumes less power, and has high contrast as the OLED does not have a backlight layer (unlike LCDs). The board’s firmware uses an I²C command structure to maintain speed by updating only the part of the screen that changes.
