## Description

The Adafruit Grayscale 1.5" OLED Display delivers 128×128 pixels with 16 levels of grayscale on a crisp, high-contrast OLED panel. Driven by the SSD1327 controller, it connects via I²C or SPI and includes STEMMA QT / Qwiic connectors for solderless I²C hookup. An on-board 3.3V regulator and 12V boost converter handle power, and all logic pins are level-shifted for compatibility with both 3.3V and 5V devices. With no backlight needed, OLED technology provides excellent contrast and low power consumption. The 4-bit grayscale capability lets you display smooth gradients and shading, going well beyond simple monochrome graphics. Key Features 128×128 Grayscale OLED – 16 levels (4-bit) of grayscale for smooth shading and gradients 1.5" Diagonal – Compact yet highly readable due to OLED contrast SSD1327 Controller – Supports I²C and SPI communication STEMMA QT / Qwiic Connectors – Solderless I²C connection, compatible with SparkFun Qwiic ecosystem Level-Shifted Logic – Works with both 3.3V and 5V microcontrollers On-Board Power Regulation – 3.3V regulator and 12V boost converter included Arduino and CircuitPython Libraries – Ready-to-use driver support Ideal For Displaying graphics, icons, and data with grayscale detail Sensor dashboards and status displays Embedded projects needing a compact, high-contrast screen Prototyping with STEMMA QT / Qwiic for quick, solderless connections Package Contents 1× Adafruit Grayscale 1.5" 128×128 OLED Display with STEMMA QT connectors Important: This display requires approximately 8 KB of SRAM to buffer. It is not compatible with Arduino UNO (ATmega328) or similar low-RAM boards. Use a microcontroller with at least 16 KB RAM, such as SAMD21, SAMD51, ESP32, nRF52, or Teensy. Note: OLED pixels will gradually dim after extended use (1,000+ hours). Turn off the display when not in use to maintain uniform brightness over time.
