The LCD2004 Display Module is a 20-column by 4-row alphanumeric LCD screen based on the popular HD44780 controller, designed for displaying text, numbers, and simple symbols in embedded systems and Arduino projects.
It can be used in either parallel or I2C (with adapter) mode, making it flexible and easy to integrate with Arduino, ESP32, STM32, and Raspberry Pi boards.
With its bright backlight, high contrast, and wide viewing angle, the LCD2004 provides excellent readability even in low-light environments. It’s perfect for data monitoring, menu systems, and DIY control panels.
