DIYables OLED 128x32
Click to zoom
Quick Overview
This DIYables OLED 128x32 display features a 0.91 inch white self-luminous screen with 128x32 pixel resolution and I2C interface. The SSD1306 driver chip ensures easy integration with Arduino, ESP32, ESP8266, and Raspberry Pi using the popular Adafruit SSD1306 library.
The compact 12mm x 38mm module operates on 3V to 5V, making it compatible with both 3.3V and 5V microcontrollers. The OLED technology provides excellent contrast with >160° viewing angle and ultra-low power consumption (0.08W at full brightness), requiring no backlight.
Ideal for displaying text, graphics, sensor data, and status information in embedded projects. The I2C interface simplifies wiring with just 4 pins (VCC, GND, SCL, SDA) at address 0x3C.
