Description
The 2.42-inch 128×64 Blue OLED Display Module is a large monochrome graphic display designed for microcontroller and embedded electronics applications.
Featuring the SSD1309 controller and a 128×64 pixel resolution, the module can display text, numbers, symbols, icons, menus, sensor readings, graphs, and custom graphics.
Its larger 2.42-inch screen provides significantly more viewing area than common 0.96-inch OLED displays, making it particularly suitable for projects where information needs to be clearly visible.
The display uses an I2C/IIC communication interface, requiring only four connections: VCC, GND, SCL, and SDA. This simplifies wiring and reduces the number of GPIO pins required from your microcontroller.
OLED technology allows individual pixels to emit their own light without requiring a conventional backlight. The result is a bright blue-on-black display with high contrast and excellent readability.
It is suitable for use with popular development platforms such as Arduino, ESP32, ESP8266, Raspberry Pi Pico, STM32, and other compatible microcontrollers.
