Everyone loves the 1602 character LCD, is cheap and works out of box! But the need for 6 to 10 GPIOs is the pain. It takes most of GPIO of Arduino and other microcontroller. Now with this I2C or two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.
This is a 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. If you already has I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino based project.
Wide viewing angle and high contrast. Built-in industry standard HD44780 equivalent LCD controller.
Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices.
Note: If the display is not clear (or blank), try to adjust the contrast level by tuning the on-board potentiometer.
