Arduino Due FET Shield

I got this premade device and I'm having a hard time finding any information for the MOSFET shield, It is a shield for the Arduino Due.
I can't find the specs for the FET Shield. On one end of the circuit board, it is clearly labeled: "DUE_FET_Shield_Rev_A db 02/15/2013".
It is obviously made for the Arduino Due specifically. The RESET switch shorts that pin on the DUE. The FUNCTION switch is routed through a MAX6817EUT (CMOS Switch Debouncer) then it goes to the Arduino pin 52 (AD14(RXD3)).
I attempted to find information on this forum, but I never found any way to narrow my search.
If anyone has any info or has used this board, please respond.
