Product Overview

LCD2004 20x4 character LCD display is an alphanumeric screen module designed to show text, numbers, symbols, menus, and live status data in embedded electronics projects. This LCD2004 format provides four rows of twenty characters, giving you more room than a 16x2 display for sensor readings, clocks, configuration prompts, debug messages, and user interfaces. The blue backlight improves readability in dim environments, making it a practical display module for Arduino, Raspberry Pi, ESP32, and general microcontroller prototyping, as well as robotics, home automation panels, test equipment, and DIY control systems.
