1.I2C/TWI LCD2004 module compatible with Gadgeteer is a cool lcd display with a high speed I2C serial bus from DFRobot. With the limited pin resources, your project may be out of resources using normal LCD shield. The LCD display is a 4×20 character STN white display with a blue LED backlight.

2.With this I2C interface LCD module, you only need 2 lines (I2C) to display the information.If you already have I2C devices in your project, this LCD module actually cost no more resources at all. Fantastic for Arduino based project.

3.This board is able to be powered by 5V or 3.3V which make it compatile with both Gadgeteer, DUE 3.3V system and standard UNO/Mega 5V system.

4.I2C Address: 0x20-0x27(0x20 default).

5.Number of Characters: 20 characters x 4 Lines.

6.Supply voltage: 5V(via Pin) 3.3V(via IDC10).

7.Dot size: 0.55 x 0.55 mm.
