This is another great blue backlight LCD display. As the pin resources of Arduino controller are 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. 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.
Specification - I2C Address: 0x3F
- Backlight (Black character on Blue background)
- Supply voltage: 5V
- Size: 82x35x18 mm
- Come with IIC interface, which can be connected by DuPont Line
