Product Overview

This monochrome 1.3" graphic OLED display offers exceptional readability with its high-contrast white pixels. Featuring a 128x64 resolution, it requires no backlight, leading to reduced power consumption and a crisp visual output. The integrated SSD1306 controller supports both I2C and SPI communication. Designed for ease of use, it operates on 3.3V logic levels and includes onboard 3.3V regulation and level shifting for compatibility with 3V or 5V devices. The updated design incorporates auto-reset circuitry and STEMMA QT / Qwiic connectors for solderless I2C connectivity. This display is ideal for projects requiring clear text and graphics, with libraries available for Arduino and Python/CircuitPython. It requires a microcontroller with more than 1KB of RAM for buffering.
