I2c Serial Adapter for LCD 1602 is a converter module to change parallel communication from LCD to I2C.
With this adapter module, the number of IO pins required for communication from minsys to LCD is very small (only requires 2 IO pins for I2C).
This module can be directly soldered to your LCD board, very suitable for LCD characters 16×2, 20×4, dsj (1602 compatible)

Arduino has limited pins. If we want to connect the LCD and several sensors to Arduino, it is possible that the existing pin is not enough. With this module, we can use LCDs with just 2 cables. Backlights and contrast can be adjusted with a potentiometer.

Official explanation:
Using the I2C interface on this will save IO pins on your MCU boards. With this board, you can save 5 IOs, that means you only need 2 IO pins to drive it from MCU. If you already have I2C devices in your project, this LCD module actually costs no more IO resources at all.
