Description
Product Overview
The 1.3-inch Blue 8-Pin OLED Display Module is a high-performance monochrome graphic display featuring the SH1106 driver IC from Sino Wealth, designed for embedded applications requiring crisp visual output and flexible connectivity . With a sharp 128×64 pixel resolution, this 8-pin variant provides the most comprehensive interface options, supporting both SPI (3-wire/4-wire) and I2C communication protocols, as well as 8-bit parallel interfaces for maximum versatility .
The key distinguishing feature of this 8-pin module is the inclusion of both CS1 (Chip Select 1) and CS2 (Chip Select 2) pins, which in addition to the SO (Serial Data Out) pin, allow for advanced communication modes and multi-device bus sharing without conflicts. The multiple chip select lines enable this module to function seamlessly in complex projects with multiple peripherals sharing the same SPI bus.
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 (>2000:1), and >160° viewing angles . The bright blue monochrome display ensures excellent readability in all lighting conditions while consuming minimal power.
The module includes an embedded 132×64-bit SRAM display buffer and an on-chip oscillator, reducing external component requirements . With a built-in charge pump circuit generating the necessary OLED driving voltage, the module requires only a single 3.3V–5.5V power supply, making it compatible with both 5V (Arduino) and 3.3V (ESP32, Raspberry Pi) systems .
