A compact 0.91" OLED display module with 128 × 32 pixel resolution, capable of displaying up to 3 lines of text. As an OLED, it has no backlight — resulting in thinner construction, lower power consumption, and higher contrast compared to LCD displays. The optimised firmware updates only changed portions of the screen for efficient I2C communication.
