4.  Evaluation Board Schematics

The 14-pin and 16-pin devices have identical circuits, with the only difference being two additional NC (No Connect) pins on the 16-pin
devices.  To  reduce  the  number  of  schematics  included  in  the  user’s  guide,  a  16-pin  and  an  8-pin  schematic  are  shown.  To  see  the
schematic, layout, and BOM for each individual EVB, refer to “Schematics and Layouts” on the product webpage.
