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.
