The 0.96-inch I2C/IIC OLED Blue Display Module is a compact, high-contrast display designed for microcontroller, IoT, robotics, and embedded electronics projects.
Featuring a 128 × 64 pixel resolution and the widely supported SSD1306 controller, the module provides a clear blue OLED display for showing text, numbers, sensor readings, icons, menus, and custom graphics.
Communication is handled through the I2C (IIC) interface, requiring only four connections: VCC, GND, SCL, and SDA. This simplifies wiring and reduces the number of microcontroller GPIO pins required.
OLED technology is self-emissive and does not require a separate backlight, providing excellent contrast and sharp visibility in a compact 0.96-inch form factor.
