0.91" OLED 128x32-White backlight

Slim 128 x 32 High-Contrast OLED Screen: Displays crisp white text, graphic indicators, and custom icons against a true pitch-black background with wide viewing angles exceeding 160°.

Compact Ultra-Narrow Form Factor: Designed in a slim 0.91-inch rectangular layout, making it ideal for narrow project enclosures, dongles, and space-constrained builds.

4-Pin I2C (IIC) Serial Interface: Communicates using only 4 pins (GND, VCC, SCK/SCL, SDA), leaving maximum GPIO availability for sensors, buttons, and actuators.

Self-Luminous Energy Efficiency: OLED technology illuminates individual pixels directly without requiring a backlight, drastically conserving battery power in portable projects.

Industry-Standard SSD1306 Driver: Powered by the SSD1306 controller IC, natively supported by popular graphics libraries like Adafruit SSD1306/GFX and U8g2 for Arduino, ESP32, and Raspberry Pi.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board with an integrated glass OLED panel and standard 2.54mm header pins.

Power Supply & Operating Voltage: Operates safely on 3.3V–5V DC power and logic levels. Always double-check pin layout sequencing prior to powering up to prevent reverse polarity damage.

Handling Precautions: Hold carefully by the outer circuit board edges. Avoid applying direct pressure or physical force to the delicate glass display surface.

Environmental Limits: Operating temperature range spans -30°C to +70°C. Keep protected from static discharge, metallic dust, and liquid moisture.

Ideal for Ultra-Compact Enclosures: Position as the go-to micro display solution for slender builds, slim handheld tools, and space-restricted hardware cases.

Universal Microcontroller Compatibility: Emphasize effortless plug-and-play integration with Arduino UNO/Nano, ESP8266, ESP32, STM32, and Raspberry Pi Pico.

Recommended Cross-Sell Add-ons: Pair with Arduino Nano Boards, ESP32 IoT Boards, Solderless Breadboards & Jumpers, and Mini Environmental Sensor Modules.

Perfect for Telemetry Bars & Status Displays: Great choice for displaying real-time battery status meters, IP address indicators, WiFi signal strength, and compact sensor telemetry.
