The 0.96″ Yellow+Blue I2C OLED LCD Module is a compact, dual-color display designed for microcontroller projects, embedded systems, and DIY electronics. It features a 128×64 pixel resolution with a distinctive yellow and blue split-screen layout — the top portion of the display shows yellow text or graphics, while the bottom portion shows blue. This two-tone design is particularly useful for separating different types of information, such as a yellow status header and blue data fields, or a yellow title area and blue content region.

At the heart of the module is 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.

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 yellow+blue color scheme provides visual distinction between screen regions and can be used to create more engaging user interfaces.

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).

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″ Yellow+Blue I2C OLED Module provides a reliable, visually distinctive display solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.

Usage

Getting Started

  1. Connect power — Connect VDD to 3.3V or 5V and GND to ground.

  2. Connect I2C lines — Connect SCK to your microcontroller‘s I2C clock (SCL) and SDA to the I2C data line.

    • Arduino Uno: SCL → A5, SDA → A4

    • ESP32: SCL → GPIO22, SDA → GPIO21 (default)

    • ESP8266: SCL → D1, SDA → D2

  3. Install the library — Install the Adafruit_SSD1306 or U8g2 library through the Arduino Library Manager. You will also need the Adafruit_GFX library for graphics primitives.

  4. Find the I2C address — Run an I2C scanner sketch to confirm the display’s address (typically 0x3C).

  5. Upload a test sketch — Use a basic example to display text or graphics. The Adafruit_SSD1306 library includes a ssd1306_128x64_i2c example for testing.

Color Layout Notes

The yellow+blue display has two distinct regions:

  • Top section (yellow): Approximately the top 16 pixels of the 64-pixel height

  • Bottom section (blue): The remaining 48 pixels

When designing your UI, place headers, titles, or status indicators in the yellow region, and data fields, menus, or content in the blue region.

Typical Applications

  • Weather stations — Yellow header for location/time, blue data for temperature and humidity

  • Digital clocks — Yellow for time, blue for date and additional info

  • Sensor readouts — Yellow for sensor name, blue for readings

  • Menu systems — Yellow for menu title, blue for menu items

  • Wearable devices — Compact dual-color display for portable electronics

  • Instrument panels — Status displays with visual information hierarchy

Notes for Business Buyers

  • Visual distinction — Dual-color layout helps separate information types without complex graphics.

  • Low cost — Affordable display solution for volume production and educational kits.

  • Simple integration — 4-pin I2C interface reduces wiring complexity and microcontroller pin usage.

  • Suitable for bulk purchasing — Ideal for product development, educational programs, and commercial deployments.
