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.\n\nWith 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.\n\nKey Features\n\n\n128×128 Grayscale OLED – 16 levels (4-bit) of grayscale for smooth shading and gradients\n\n1.5\" Diagonal – Compact yet highly readable due to OLED contrast\n\nSSD1327 Controller – Supports I²C and SPI communication\n\nSTEMMA QT / Qwiic Connectors – Solderless I²C connection, compatible with SparkFun Qwiic ecosystem\n\nLevel-Shifted Logic – Works with both 3.3V and 5V microcontrollers\n\nOn-Board Power Regulation – 3.3V regulator and 12V boost converter included\n\nArduino and CircuitPython Libraries – Ready-to-use driver support\n\n\nIdeal For\n\nDisplaying graphics, icons, and data with grayscale detail\nSensor dashboards and status displays\nEmbedded projects needing a compact, high-contrast screen\nPrototyping with STEMMA QT / Qwiic for quick, solderless connections\n\n\nPackage Contents\n\n1× Adafruit Grayscale 1.5\" 128×128 OLED Display with STEMMA QT connectors\n\n\n\nImportant: 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.\n\n\n\nNote: 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.\n\n\nResources\n\nSTEMMA QT Introduction\nArduino SSD1327 Library (GitHub)\nCircuitPython SSD1327 Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":3812,"title":"Default Title","sku":"AF-4741","price":45.74,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
