0.42" 72x40 OLED display, I2C, white

Product detailed description

The OLED display with a 72×40 pixel resolution and a 0.42" diagonal is a compact monochromatic module ideal for displaying basic information, icons, or small graphic elements in projects with Arduino, ESP32 or other microcontrollers. The display uses OLED technology, meaning it requires no backlight – individual pixels emit their own light, creating a bright white image on a deep black background with high contrast. Communication is handled via a simple two-wire I2C bus, ensuring minimum use of microcontroller inputs. The SSD1306 controller is well-supported by common libraries, making setup easy even for beginners.
