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.
