1602 16×2 HD44780 Character LCD Display Module with I2C PCF8574 Interface Adapter 5V Blue Screen

This 1602 16×2 character LCD module is a popular display solution for Arduino and microcontroller projects. It features a blue backlight with white characters and comes with an I2C (IIC) PCF8574 interface adapter, allowing easy connection using only two data wires. It is ideal for displaying text, values, and system status in DIY electronics and training projects.

Product Overview

The 1602 LCD display is based on the HD44780 controller, which is widely supported and easy to use. The operation is such that the LCD displays 16 characters per line across 2 lines, thereby providing a clear and readable text interface. With the I2C serial adapter attached, wiring is greatly simplified, making this module very suitable for beginners, students, and rapid prototyping applications.
