It is another great BLUE backlight LCD display.
As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card.
However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires.
If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.

Backlight (white character on Blue background)
Supply voltage: 5V
Size: 82mmx35mmx18 mm
Come with IIC interface, which can be connected by DuPont Line.

Package Included:

1 X Blue Display IIC/I2C/TWI/SPI Serial Interface 1602 16X2 Character LCD Module

• LCD type: Characters.
• Comes with Arduino 1602 I2C interface 4-wire 1602 screen
• LCD display module white on Blue with Backlight, Built-in industry standard HD44780 equivalent LCD controller.
• Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices.
• IO port of Arduino control board is only 20,so IO ports is not enough for many sensor, SD card, relay modules, the original 1602 screen need 7 IO ports to drive up, and this module can save 5 IO ports.
