3.12" OLED Display Module - 256x64 Resolution + SSD1322 Driver, SPI Interface Compatible with Arduino/ESP8266

This 3.12-inch OLED display module employs high-contrast self-luminous technology, enabling clear display of text and graphics without the need for a backlight. It supports a resolution of 256×64 and 16 levels of grayscale, making it suitable for displaying complex UIs or data charts. It is equipped with an SSD1322 driver chip and communicates with the main controller via a standard 4-wire SPI interface, compatible with mainstream development platforms such as Arduino, ESP8266, and STM32. The module size is 100mm x 35mm, with installation holes at the four corners, facilitating its fixation on the device panel. It is widely used in smart instruments, industrial control, and smart home panels, among other scenarios.
