The 0.96″ Blue I2C OLED LCD Module is a compact, high-contrast display designed for microcontroller projects, embedded systems, and DIY electronics. It features a 128×64 pixel resolution and uses the SSD1315 driver chip — a modern, widely supported controller that offers excellent compatibility and performance. With its 4-pin I2C interface (GND, VDD, SCK, SDA), the module requires only two data lines to connect to your microcontroller, making it one of the simplest displays to integrate into any project.
At the heart of the module is the SSD1315 controller, which drives the 0.96-inch OLED panel. OLED technology provides self-illuminating pixels — meaning each pixel emits its own light without a backlight — resulting in true blacks, infinite contrast ratio, and wide viewing angles. The blue monochrome display offers crisp, clear visibility, making it ideal for displaying text, numbers, icons, and simple graphics.
The I2C interface (also written as IIC) uses only two signal wires: SCK (serial clock) and SDA (serial data) , along with power (VDD) and ground (GND). This 4-pin design simplifies wiring and frees up microcontroller pins for other peripherals. The module supports standard I2C addresses (typically 0x3C or 0x3D), and multiple displays can theoretically share the same bus with different addresses.
The module operates from 3.3V to 5V logic levels, making it compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other popular platforms. It consumes very little power — typically less than 20mA during operation — making it suitable for battery-powered devices and portable electronics. The compact 27 × 27 mm form factor with mounting holes allows easy integration into custom enclosures and project panels.
Supported development environments include Arduino IDE (with the Adafruit_SSD1306 and U8g2 libraries), ESP-IDF, and MicroPython. The U8g2 library provides extensive font support, graphics primitives, and display control functions, making it easy to create professional-looking user interfaces.
Whether you are building a weather station, a digital clock, a sensor readout, a menu system, or a wearable device, the 0.96″ Blue I2C OLED Module provides a reliable, high-contrast display solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
