Description
Product Overview
The 1.3-inch White 7-Pin OLED Display Module is a compact, high-contrast monochrome graphic display designed for embedded applications requiring crisp visual output and flexible connectivity. Powered by the SH1106 driver IC with a sharp 128×64 pixel resolution, this 7-pin variant offers the highest flexibility, supporting both 4-wire SPI (default) and I2C communication protocols .
The dedicated Chip Select (CS) pin allows multiple SPI devices to share the same bus without conflicts—essential for complex projects with multiple peripherals such as SD cards, sensors, or additional displays .
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 white monochrome display ensures excellent readability in all lighting conditions while consuming minimal power—approximately 0.04W during normal operation (20mA typical) .
The module includes an on-board voltage regulator that accepts 3.3V–5.5V power, making it compatible with both 5V (Arduino) and 3.3V (ESP32, Raspberry Pi) systems . Four mounting holes (for M3 or #4 screws) provide secure installation options .
