I2C LCD Adapter Module for 16x2 and 20x4 LCD Displays
VAT inclusive; Computed calculations added locally.
Overview
The I2C LCD Adapter Module provides a simple and space-saving way to interface standard character LCD displays with Arduino and other microcontroller platforms. By converting the LCD's parallel interface to an I2C serial interface, it significantly reduces the number of GPIO pins required for display communication.
This compact adapter is designed to attach directly to compatible 16x2 and 20x4 LCD modules, making it useful for projects where available I/O pins are limited. With an I2C connection, the display can typically be controlled using just SDA and SCL, while power and ground complete the connection.
It is a practical choice for Arduino projects, sensor systems, robotics, automation, IoT prototypes, and embedded displays where a character LCD is required alongside other peripherals.
