This is another great blue backlight LCD display. 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 LCD module, you will be able to realize data display via only 2 wires. This LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
- Interface: I2C
- I2C Address: 0x27
- Pin Definition : VCC、GND、SDA、SCL
