Prakti LCD 20x4-LCD-Character Display blue with IIC-I2C-Serial-Interface-Adapter-Module

Product Description

The Prakti LCD 20×4 Character Display (Blue Backlight) with IIC/I2C Serial Interface Adapter Module is a combined display solution perfect for embedded projects requiring a clear, easy-to-read information panel. The 20×4 character LCD uses a standard HD44780-compatible controller, while the included I2C adapter module enables serial communication using just two microcontroller pins (SDA and SCL).

This module is ideal for use with microcontrollers such as Arduino, ESP32, STM32, and SBCs such as Raspberry Pi (with appropriate I2C interface connections). The I2C adapter reduces pin requirements and wiring complexity, enabling quick prototyping and cleaner system design. This assembly is commonly used in IoT dashboards, sensor data displays, automation panels, robotics, and educational electronics.
