16x2 LCD Display Module - Green display with I2C

The 16×2 LCD Display Module with I²C Interface is a compact and easy-to-use display designed for showing text and simple information in embedded electronics projects. It can display 16 characters per line across 2 lines, making it ideal for displaying sensor data, system messages, menus, and project status information.

Unlike standard parallel LCD modules, this version includes an I²C serial interface, which significantly reduces the number of required microcontroller pins. Instead of using many data lines, the display communicates through just two wires (SDA and SCL), making wiring simpler and saving valuable GPIO pins.

This module is widely used in microcontroller projects and works seamlessly with platforms like Arduino Uno, ESP32, and Raspberry Pi.
