OLED DISPLAY MODULE (128×64)

General Description:

An OLED display with a resolution of 128x64 pixels is a versatile and popular module in embedded systems and DIY electronics. Utilizing Organic Light Emitting Diode technology, this display offers high contrast and vivid images without the need for a backlight, as OLEDs generate their light. It typically communicates through I2C (using SDA for data and SCL for the clock) or SPI (using MOSI for data, SCK for the clock, and CS for chip select) interfaces, making it compatible with various microcontrollers. The display usually operates at a voltage of 3.3V or 5V and is known for its low power consumption, which makes it ideal for battery-powered projects.

Working Principle:

The OLED (Organic Light Emitting Diode) display is based on electroluminescence, where organic compounds emit light when an electric current is applied. OLED displays differ from LCDs because each pixel emits its own light, meaning no backlight is required.

Specifications:

1. Display Type: 128×64 pixel resolution OLED display (available in white, blue, or yellow).
2. Power Supply Compatibility: Supports both 3.3V and 5V input levels.
3. Brightness Control: Adjustable luminance through software (library support).
4. Current Consumption: Typically ranges from 0.1 mA (idle) to 25 mA (active display).
5. Communication Protocol: I²C interface using only 2 digital pins (SDA and SCL).
6. Driver IC: Uses SSD1306 controller with built-in display RAM and control logic.
7. Display Capability: Supports both text and bitmap graphics; can render custom fonts and icons.
8. Pixel Technology: Self-emissive pixels, no backlight required (each pixel generates its own light).
9. Mounting Features: Equipped with solderable header pins and mounting holes for easy installation.
10. Module Dimensions: Approximately 27mm × 27mm × 4mm (may vary by manufacturer).

Applications:

1. Wearable Devices
2. Embedded Systems
3. Home Appliances
4. Portable Electronics
5. Medical Devices
