EV-ADUCM350-BIO3Z-ND (BIO3Z REV. B) schematic

Hi All, 

I've recently bought a Eval-ADUCM350EBZ development board and it came with a EV-ADUCM350-BIO3Z-ND ( BIO3Z REV. B) daughter board. 

I try to understand how to use this board and has failed to find any document/schematic related to this board. 

Can anyone please help?

Thank you very much,
