LCD 20x4 Character Display Module Blue Background With I2C Adapter
This I2C 2004/20x4 LCD Module features a sleek blue backlight with white text for clear and attractive display output. It supports displaying 4 lines of text with 20 characters per line. The module uses an I2C interface that only requires two I/O pins, freeing up other pins on your microcontroller for additional uses. The contrast can be easily adjusted using the potentiometer on the back, and the backlight can be turned off by removing the jumper cap.
