information.

Character LCD

The starter board includes a single 14-pin 0.1" pitch dual-row header that interfaces to
a 16 character × 2 line Lumex character LCD display. The character LCD has a 14-pin
receptacle that mounts directly to the board's 14-pin header, so it can be easily
removed for access to components under the display. You can also use the header for
debugging or other purposes.
