IIC I2C SPI Serial Interface Board Module Port For Arduino 1602LCD

Description IIC/I2C/TWI/SPI Serial Interface for Arduino 1602LCD. 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 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: 0X20~0X27 (the original address is 0X20,you can change it yourself) 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 2004 LCD
