The LCD2004 is a reliable 20×4 alphanumeric display module designed for clear text-based output in embedded and electronic projects. It features a yellow backlight with black characters, ensuring excellent readability in various lighting conditions. This module combines a standard 16-pin parallel LCD with an onboard I²C (IIC) adapter, significantly reducing wiring complexity and GPIO usage on microcontrollers.

Operating at 5 V DC, the LCD2004 is widely compatible with popular development boards such as Arduino, Raspberry Pi (with level matching), and other 5 V microcontrollers. Each character is formed using a 5×8 dot matrix, delivering crisp and consistent text rendering. With support for up to 80 characters displayed simultaneously, it is ideal for showing sensor data, menus, system status, and user prompts.

Its robust operating temperature range and PCB mount design make it suitable for both prototyping and deployed embedded systems where dependable visual feedback is required.
