{"title":"Monochrome 0.91\" 128x32 I2C OLED Display - STEMMA QT / Qwiic","handle":"monochrome-0-91-128x32-i2c-oled-display-stemma-qt-qwiic","url":"/products/monochrome-0-91-128x32-i2c-oled-display-stemma-qt-qwiic","description":"This compact 0.91\" monochrome OLED display packs 128×32 individually controllable white pixels into a tiny, highly readable package. With no backlight needed, OLEDs deliver exceptional contrast and low power consumption — perfect for status displays, sensor readouts, and compact interfaces.\n\nThe breakout board includes support circuitry for 3.3V and 5V logic levels, auto-reset circuitry (making the reset pin optional), and STEMMA QT / Qwiic connectors for solderless I2C wiring. Simply connect with a STEMMA QT cable and start displaying text and graphics.\n\nKey Features\n\n\n128×32 OLED Display – High contrast white pixels on black background\n\n0.91\" Diagonal – Compact but highly readable\n\nI2C Interface – Just two data wires plus power\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection\n\n3.3V and 5V Compatible – Works with Feather, Raspberry Pi, Arduino, and more\n\nAuto-Reset Circuitry – Reset pin is optional\n\nLow Power – ~20 mA average from 3.3V supply\n\n\nSpecifications\n\n\nDisplay Type: Monochrome OLED (white)\n\nResolution: 128×32 pixels\n\nSize: 0.91\" diagonal\n\nInterface: I2C\n\nLogic Level: 3.3V–5V\n\nPower Consumption: ~20 mA typical @ 3.3V\n\n\nIdeal For\n\nSensor data readouts\nStatus displays for IoT projects\nWearable electronics\nCompact embedded interfaces\n\n\n\nNote: Requires a microcontroller with more than 512 bytes of RAM for display buffering. OLED pixels may dim after extended continuous use (~1000+ hours) — turn off the display when not in use to preserve brightness. STEMMA QT / Qwiic cable sold separately.\n\n\nPackage Contents\n\n1× Monochrome 0.91\" 128×32 I2C OLED Display Breakout\n\n\nResources\n\nMonochrome OLED Breakouts Tutorial (Arduino & Python)\nSTEMMA QT Overview\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2790,"title":"Default Title","sku":"AF-4440","price":25.34,"on_sale":false,"in_stock":true,"available_quantity":77,"option1":"Default Title"}]}
