Apply to:
With the help of the LCD module, you can display most things through the programming code that compatible with Arduino and Raspberry pi.

Practical to use:
LCD display with I2C serial interface has 2 bidirectional data lines, a serial data line and a serial clock. Through the IIC/I2C interface, it only occupies two I/O ports, thus saving more space for other uses.

With backlight
You can adjust the contrast through the contrast on the back of the potentiometer. If you don’t want to use the backlight, you can also unplug the jumper cap on the back of the LCD. Through the backlight power control, it can be set to the backlight power through a jumper connection. Insert the jumper to turn off the backlight, and remove the jumper to disconnect it.

Line output is simple:
The contrast can be adjusted by turning the blue potentiometer clockwise and decreasing the blue potentiometer counterclockwise. The potentiometer is designed on the front, so your can adjust it at any time.
