This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of for the Arduino controller is limited, your project may be not able to use a 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 have 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
