1.3 inch OLED display Module Blue for Arduino

Product Description

The 1.3 Inch 128×64 Blue OLED Display Module is a compact, high-contrast display designed for Arduino, IoT, robotics, embedded systems, and DIY electronics projects. With a 128×64 pixel resolution, it provides clear text, numbers, graphics, sensor readings, menus, and system status information.

The module uses the I2C/IIC communication interface and features a simple 4-pin connection consisting of VCC, GND, SCL, and SDA. This reduces the number of microcontroller pins required and makes the display easy to integrate with compatible development boards.

OLED technology provides bright and high-contrast output without requiring a separate backlight, making the module suitable for compact and portable electronic devices. Its small form factor is ideal for applications where both display clarity and space efficiency are important.

Specifications

Pin Description

Design and Construction

The display features a compact PCB design with a 1.3-inch blue OLED screen and a four-pin interface. The small form factor allows it to be easily incorporated into portable instruments, robots, IoT devices, control panels, and embedded electronics.

The OLED display produces its own light at the pixel level, eliminating the need for a conventional backlight. This provides clear and high-contrast output while maintaining a compact construction.

Working Principle

The module communicates with a compatible microcontroller using the I2C/IIC protocol. The microcontroller sends display commands and data through the SDA line, while the SCL line provides the clock signal for synchronized communication.

The OLED converts the received display data into illuminated pixels, allowing the user to display text, numbers, icons, graphics, sensor readings, menus, and status information.
