I2C / Serial LCD
Serial LCD includes the standard LCD module and serial controller to provide a serial
communication interface for your microcontroller  or PC. The serial controller takes care of all
commands between LCD and your microcontroller and uses only two lines for
communications.

Provision is made for up to 8 user-defined characters. The module includes also the 4x4 matrix
keypad control.
