The OLED (Organic Light-Emitting Diode) 128*32 dot matrix display module with I2C Interface is a state-of-the-art display solution that offers significant advantages over traditional LED displays. With its super-light, self-emission, high contrast, wide viewing angle, and low power consumption, this OLED screen is compatible with Arduino and easily accessible with the libraries includes.

 

Features:

1. High Contrast and Brightness: The OLED display offers high contrast, producing a brighter and crisper picture, thanks to its self-emitting properties.
2. Wide Viewing Angle: With a viewing angle of up to 160 degrees, the display ensures optimal visibility from various perspectives.
3. Low Power Consumption: The OLED display does not require a backlight LED, resulting in lower power consumption—averaging around 20mA.
4. SSD1306 Controller: Utilizes the SSD1306 OLED driver controller, enabling efficient communication with the microcontroller through I2C.
5. Operating Voltage: The SSD1306 controller operates between 1.65V to 3.3V, while the OLED panel accepts a supply voltage of 7V to 15V, easily compatible with Arduino and 5V logic microcontrollers.
6. Internal Charge Pump Circuitry: The module features internal charge pump circuitry, eliminating the need for a logic-level converter.
