20X04 LCD DISPLAY WITH IIC I2C INTERFACE YELLOW
20×4 LCD display with I²C interface and yellow backlight. Compact, easy-to-use alphanumeric display for Arduino, ARM, and microcontroller projects.
The 20×4 LCD Display with I²C Interface is a versatile alphanumeric display module that shows 20 characters per line on 4 lines, making it ideal for embedded systems, DIY electronics, and industrial projects. With an onboard I²C interface, the module requires only two data lines (SDA and SCL) for communication, freeing up microcontroller pins and simplifying wiring.
The yellow backlight ensures clear visibility even in low-light environments, and the module is compatible with popular microcontrollers such as Arduino, PIC, AVR, ARM, ESP32, and STM32. It supports easy text display, cursor control, and custom characters, making it perfect for sensor data display, menu systems, and real-time monitoring.
