OLED Module (1.3 inch)
DISPLAY PRINCIPLE: The 1.3-inch OLED display module works using Organic Light Emitting Diode technology where each pixel emits light when an electric current flows through organic materials. Unlike LCD displays, OLED panels do not require a backlight because the pixels generate their own illumination. This results in higher contrast, faster response time, and lower power consumption.
MODULE STRUCTURE: The module consists of a 1.3-inch OLED screen integrated with a controller circuit and I2C communication interface. The display has a resolution of 128 × 64 pixels and produces bright blue graphics and text on a dark background. The compact PCB includes connection pins for power and communication, allowing easy integration with development boards.
PIN CONFIGURATION: GND – Ground connection, VCC – Power supply input, SCL – Serial clock line for I2C communication, SDA – Serial data line for I2C communication
INTERFACE CONNECTION: The display communicates using the I2C serial communication protocol, requiring only two signal lines (SDA and SCL) along with power connections. This simplifies wiring and makes it compatible with Arduino, ARM boards, ESP modules, STM32, and other microcontrollers.
OUTPUT DISPLAY: The screen provides a resolution of 128 × 64 pixels, allowing the display of text, icons, simple graphics, sensor readings, and status indicators. The wide viewing angle and high contrast ensure clear visibility from different directions.
OPERATING VOLTAGE: The module operates with a supply voltage ranging from 3.3V to 5V, making it suitable for most embedded development boards.
PHYSICAL CHARACTERISTICS: Display Size: 1.3 inch, Display Type: OLED, Resolution: 128 × 64 pixels, Interface Type: I2C (IIC), Driving Voltage: 3.3V – 5V, Weight: Approximately 7 g
APPLICATION SCOPE: This OLED display is commonly used in wearable electronics, smart devices, IoT monitoring systems, portable measuring instruments, robotics control panels, and embedded user interfaces. It is also widely used in DIY electronics projects, diagnostic tools, compact dashboards, and medical devices such as pulse monitors and portable health equipment.
