Features:
- OLED screen with 128x64 dot matrix resolution
- I2C interface for easy microcontroller integration
- SSD1306 OLED driver controller
- Self-emission technology (no backlight required)
- High contrast and up to 160° viewing angle
- Deep black color rendering
- Low power consumption (~20mA average)
- Compatible with Arduino and 5V logic microcontrollers
Description:
The OLED display module is a compact and efficient solution for applications needing clear, high-quality visuals. Utilizing OLED technology, it offers superior contrast, low power usage, and wide viewing angles. It is ideal for use in wearables, low-power embedded systems, and DIY projects. The SSD1306 driver and I2C interface simplify communication with microcontrollers such as Arduino or Raspberry Pi. The display does not require a backlight, allowing it to produce deep blacks and save power.
Principle of Work:
OLED technology allows each pixel to emit its own light. This self-emissive property removes the need for a backlight and leads to higher contrast and power efficiency. The SSD1306 driver controls each pixel via I2C communication with the microcontroller.
Pinout of the Module:

- VCC: Power input (3.3V to 5V DC)
- GND: Ground connection
- SCL: Serial Clock Line for I2C
- SDA: Serial Data Line for I2C
Applications:
- Wearables: Smartwatches, fitness bands, and health monitors
- Home Automation: Display temperature, humidity, and other readings
- Automotive: Dashboards, infotainment, and navigation systems
- Medical Devices: ECG monitors, pulse oximeters, glucose meters
- Industrial Automation: Control panels, robotic systems, data displays

Library Installation:
- Open the Arduino IDE
- Navigate to Sketch > Include Library > Manage Libraries...
- Search for u8glib in the Library Manager
- Install the official U8glib library by olikraus
- (Optional) Restart the IDE to ensure the library is loaded
Example Arduino Code:
#include "U8glib.h"
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NO_ACK); // Initialize OLED display
void setup() {
u8g.begin(); // Start the OLED
}
void loop() {
u8g.firstPage();
do {
u8g.setFont(u8g_font_6x10);
u8g.drawStr(0, 20, "Techmaze.ae");
u8g.drawCircle(64, 32, 20);
} while(u8g.nextPage());
}
