OLED display 0.96" I2C Blue-Yellow

Product Description

The 0.96” OLED display with SSD1306 driver is the classic choice for Arduino and microcontroller projects when you want a small, crisp, and easy-to-control screen. The panel has a 128×64 resolution and Yellow/Blue color zones (usually ~1/3 yellow, ~2/3 blue), which gives it a modern look without complicating the software — from a coding perspective, the display remains monochrome. Communication is via I²C, so you only need two data lines (SCL/SDA) plus power. Text and graphics (icons, simple charts, logo) render with excellent contrast, visible from almost any angle.

Ideal for: simple menus, sensor status, clocks, thermometers, portable projects, counters, visual debugging.

Technical Details

• Active diagonal: 0.96”
• Resolution: 128 × 64 pixels
• Technology: OLED (self-emissive, high contrast, no backlight)
• Panel colors: Yellow/Blue (zone distribution is hardware-defined; content is monochrome)
• Interface: I²C (IIC)
• Controller: SSD1306
• Pins: GND, VDD (VCC), SCL, SDA (4 pins, 2.54 mm pitch)
• Supply voltage: 3.3 V – 5 V (typical)
• Usual I²C address: 0x3C (depending on batch, some boards may allow 0x3D)
• Power consumption: very low (typical for OLED, no backlight)
• Compatibility: Arduino/AVR (Uno, Nano, Pro Mini), ESP8266/ESP32, STM32, Raspberry Pi Pico, etc.
• Module dimensions: approx. 27 × 27 × 4 mm (indicative, may vary slightly by manufacturer)
• Mounting: mounting holes for M2 screws (where provided)

Wiring Diagram & Code Example (Arduino)

Quick wiring (Arduino UNO)

• OLED GND → Arduino GND
• OLED VDD → 5V (or 3.3V)
• OLED SCL → A5 (SCL)
• OLED SDA → A4 (SDA)

On modern boards (e.g., Arduino Leonardo/Mega/ESP32) use the dedicated I²C pins labeled SCL/SDA. If you use 3.3 V, power the logic at 3.3 V as well.

Code example (Adafruit libraries)

1. Install from Library Manager: Adafruit SSD1306 and Adafruit GFX Library.
2. Upload the sketch below (address 0x3C, 128×64):

#include <Wire.h>

#include <Adafruit_GFX.h>

#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128

#define SCREEN_HEIGHT 64

#define OLED_RESET    -1        // I2C reset, unused

#define OLED_ADDRESS  0x3C      // common address for most modules

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup() {

  Wire.begin(); // start I2C

  if (!display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDRESS)) {

    for (;;); // halt if the display isn’t found

  }

  display.clearDisplay();

  // Simple text

  display.setTextSize(1);

  display.setTextColor(SSD1306_WHITE);

  display.setCursor(0, 0);

  display.println(F("ArduShop - OLED 0.96\""));

  display.println(F("SSD1306 I2C 128x64"));

  display.display();

  delay(1500);

  // Graphics: rectangle and circle

  display.clearDisplay();

  display.drawRect(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, SSD1306_WHITE);

  display.fillCircle(SCREEN_WIDTH/2, SCREEN_HEIGHT/2, 12, SSD1306_WHITE);

  display.setCursor(10, 50);

  display.setTextSize(1);

  display.println(F("Status: OK"));

  display.display();

}

void loop() {

  // example: small progress bar effect

  static int w = 0;

  display.fillRect(10, 40, w, 8, SSD1306_WHITE);

  display.display();

  delay(60);

  w += 2;

  if (w > 108) {

    display.clearDisplay();

    display.drawRect(8, 38, 112, 12, SSD1306_WHITE);

    w = 0;

  }

}

Note: the Yellow/Blue portions are hardware-defined; there are no software commands to change the colors. The displayed content is monochrome, but will appear yellow/blue depending on the zone it falls into.
