This is another great 20x4 character LCD display with I2C interface. As the pin resources of Arduino controller is limited, your project may be not able to use standard LCD module after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will only need 2 pins (SCL and SDA) to display the information. 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.
