## 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. The 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. Key Features 128×32 OLED Display – High contrast white pixels on black background 0.91" Diagonal – Compact but highly readable I2C Interface – Just two data wires plus power STEMMA QT / Qwiic Connectors – Solderless I2C connection 3.3V and 5V Compatible – Works with Feather, Raspberry Pi, Arduino, and more Auto-Reset Circuitry – Reset pin is optional Low Power – ~20 mA average from 3.3V supply Specifications Display Type: Monochrome OLED (white) Resolution: 128×32 pixels Size: 0.91" diagonal Interface: I2C Logic Level: 3.3V–5V Power Consumption: ~20 mA typical @ 3.3V Ideal For Sensor data readouts Status displays for IoT projects Wearable electronics Compact embedded interfaces Note: 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. Package Contents 1× Monochrome 0.91" 128×32 I2C OLED Display Breakout Resources Monochrome OLED Breakouts Tutorial (Arduino & Python) STEMMA QT Overview
