6.5.4. Character LCD
The Arria 10 GX FPGA development board includes a single 10-pin 0.1" pitch single-
row header that interfaces to a 16 character × 2 line Lumex LCD display. The LCD has
a 10-pin receptacle that mounts directly to the board's 10-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.
