Feature: I2C IIC Serial Interface Board Module LCD1602 Address Changeable for Arduino New This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources 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 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.
