This is great IIC/I2C/TWI/SPI Serial Interface Adapter For Arduino LCD 1602 2004.
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 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 project.
The backlight and contrast are adjusted by the potentiometer.
Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable.
