Product Description
Expand your project's data visualization with the 20x4 Character LCD Display. Providing double the screen real estate of standard 16x2 displays, this module allows for the simultaneous monitoring of multiple sensor readings, system statuses, or complex user menus. It features a vivid blue backlight with high-contrast white alphanumeric characters, ensuring excellent readability even in low-light environments. At Robogears, we recommend this display for its industry-standard HD44780-compatible controller, making it instantly compatible with nearly all microcontrollers, including Arduino, ESP32, and Raspberry Pi. The module includes an onboard potentiometer-adjustable contrast circuit and a dedicated LED backlight power pin for easy integration into your next professional build.
