digunakan untuk mengubungkan mikrokontroler dengan LCD sehingga menghemat jumlah pin. hubungan LCD biasanya membutuhkan 7 Pin. dengan menggunakan metode I2C maka hanya butuh 2 Pin. cukup praktis ;-)
Features Supply voltage: 5V the backlight and contrast is adjusted by potentiometer Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable Compatible for 1602 LCD This is another great IIC/I2C/TWI/SPI Serial Interface 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
