LCD 20×4 Display IIC/I2C
Now, with only 3 pins from microcontroller, you can display message on this LCD. Compared to parallel LCD which required at least 6 pins of I/O, this LCD offer more cost effective solution. The LCD display is four lines by 20 characters and provides basic text wrapping so that your text looks right on the display.
With the limited pin resources, your project may be out of resources using normal LCD. With this I2C interface LCD module, you only need 2 pins (I2C) to display the information, and another 2 pins for power (5V and ground). This is an ideal LCD for Arduino and Raspberry Pi based project.
