20×4 Character LCD Display with I2C Interface
Product Overview
The 20×4 (2004) LCD Module from Pro Tronix is the professional choice for projects that require more information than a standard 16×2 screen can handle. With four full lines of text, you can display multiple sensor readings, complex menus, or system status updates simultaneously without the need for scrolling.
To make integration effortless, this module features a pre-soldered I2C Serial Adapter. Instead of occupying 6 to 10 digital pins on your Arduino or ESP32, this display uses only two pins (SDA & SCL). The board also includes a built-in potentiometer for contrast adjustment and a jumper for backlight control, providing a clean and efficient setup for any build.
