About this product
A 0.91-inch monochrome blue OLED display module with a 128×32 pixel matrix. It is driven by the SSD1306 controller and connects over I2C only. Its self-emissive pixels give high contrast and low power use, making it a common choice for small status and sensor-reading screens in microcontroller projects.
