It is a great BLUE back light LCD display. As the pin resources of for 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.
*I2C Address: 0x20.
* Backlight (White character on Blue background).
*Supply voltage: 5V.
* Size: 82x35x18 mm.
* Come with IIC interface, which can be connected by DuPont Line.
