Description
Product Overview
The 1.3-inch Blue 7-Pin OLED Display Module is a high-contrast monochrome graphic display designed for embedded applications. Powered by the SH1106 driver IC with a sharp 128×64 pixel resolution, this 7-pin variant offers the highest flexibility, supporting both SPI and I2C communication protocols. The default configuration is 4-wire SPI, which provides faster data transfer compared to I2C, making it ideal for animations, real-time sensor dashboards, and dynamic user interfaces.
OLED (Organic Light Emitting Diode) technology requires no backlight, as each pixel emits its own light. This self-emissive design delivers true blacks (inactive pixels are completely off), exceptional contrast, and >160° viewing angles . The bright blue monochrome display ensures excellent readability in all lighting conditions while consuming minimal power for battery-operated projects.
The module includes a dedicated Chip Select (CS) pin, allowing multiple SPI devices to share the same bus without conflicts—essential for complex projects with multiple peripherals. With support for both 3.3V and 5.5V power supply, it works with Arduino (using level shifters for logic pins), ESP32, STM32, and Raspberry Pi .
