1.This is a great IIC/I2C/TWI/SPI Serial Interface. 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 via only 2 wires.
If you already has I2C devices in your project, this LCD MODULE is fantastic for Arduino based project.
2.I2C Address: 0X20~0X27 (the original address is 0X27,you can change it by yourself)
3.Supply voltage: 5V
4.the backlight and contrast is adjusted by potentiometer
5.Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
6.Compatible for 1602 LCD 2004 LCD
