OLED Display 0.96″ 128×64 Blue — I2C, SSD1306, Arduino

The most popular OLED display for Arduino projects — a 0.96-inch OLED with 128×64 pixel resolution and blue pixels, driven by the SSD1306 I2C controller. OLED displays emit their own light with no backlight required, delivering perfect black levels, extremely high contrast, and lower power consumption than LCD displays. Connect with just 2 wires (SDA + SCL) and display graphics, text, and sensor data in minutes with the Adafruit SSD1306 library.
