0.91-inch 128×32 blue OLED display module
0.91-inch 128×32 blue OLED display module with I²C interface—high-contrast, low-power, Arduino compatible for IoT and embedded projects.
The 0.91-inch 128×32 Blue OLED Display Module is a compact, high-contrast display designed for embedded and IoT projects. With a 128×32 pixel resolution, it delivers sharp text, icons, and simple graphics in a bright blue monochrome OLED panel.
This module supports a 4-pin I²C/IIC interface (VCC, GND, SDA, SCL), simplifying connection and minimizing GPIO usage, making it ideal for Arduino, ESP32, ESP8266, Raspberry Pi, and STM32 projects. Its small form factor and low power consumption make it perfect for wearables, smart devices, IoT applications, and compact display projects.
The OLED technology ensures a wide viewing angle, high brightness, and excellent visibility even in low-light conditions, making it ideal for displaying sensor readings, system status, messages, and simple graphics.
