IIC/I2C 1602 Serial LCD Display.
The IIC/I2C 1602 Serial LCD Display is a clever little unit for 1602 and 2004 LCD displays, to minimize the number of wires needed to connect a 1602 LCD to your Arduino. This is done by translating serial input over just a few wires into parallel input that will then be sent to LCD Displays.
This is another great blue backlight LCD display. As the pin resources of the Arduino controller are limited, your project may not be able to use a normal LCD shield after being connected with a certain quantity of sensors or SD cards. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already have I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino-based projects.
