The board in this directory is a 5x5 keyswitch matrix meant to be connected to
the Calypso chip's keypad interface (KBR and KBC lines), or more specifically
to the corresponding group of pins on the expansion interface on iWOW DSK or
FC Caramel2 boards.

The 5x5 keyswitch matrix itself is fully generic, but PCB silk screen labels
next to each button assign logical meanings that correspond to TI's original
D-Sample keypad layout.
