20x4 2004A IIC I2C enabled LCD Display Blue screen arduino raspberry pi
20x4 LCD display for Arduino with I2C interface, saving pins. White text on blue, adjustable contrast, powered by 5V/3.3V, standard connectors.
This is a 20x4 Arduino compatible LCD display module with high speed I2C interface. It is able to display 20x4 characters on two lines, white characters on blue background.
Generally, LCD display will run out of Arduino pin resource. I
t needs 6 digital pins and 2 power pin for a LCD display.
If you want to build a robot project, it will be a problem with Arduino UNO and LCD display.
This I2C 20x4 LCD display module is designed for Arduino microcontroller. It is using I2C communication interface, With this I2C interface, only 2 lines (I2C) are required to display the information on any Arduino based projects.
It will save at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect it with jumper wire directly.
Blue backlight with white text character LCD. The LCD display has the I2C backpack module mounted on the back side which requires only two connected wires for data and two wires to supply ground and +5V to power the display. The I2C backpack also allows you to change the I2C address of the module,
