LIVISN MEGA 2560, 20x4 LCD Display Module IIC/I2C/TWI Serial LCD2004 2004 with Screen Panel Expansion Board Green on Yellow

The latest high-quality I2C LCD2004-character LCD display module, a new high-quality 4 line 20 character LCD module not only set the contrast control knob selector switch also has a backlight and IIC/I2C communication interface.
With IIC/I2C interface, it only takes two I/O port thus saving more for other usages. You can adjust the contrast by the potentiometer at its back. If you don’t want the back light, you can also unplug the jumper cap at the LCD back.
For Development IDE beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the (compatible with) Development IDE Sensor Shield V5.0 sensor expansion board IIC device interface can, GM 4P sensor connection cable, programmed through the (compatible with) Development IDE controller, you can easily identify the slogan, sensor data records.
With this shield, you can display whatever you want by programming the (compatible with) Development IDE board. Therefore, this is a perfect choice to make your project more interesting and vivid!
