EVAL-AD5933EBZ from two to four electrodes

I'm currently trying to expand the AD5933 evaluation board to use tetrapolar electrode system. My current problem is, I can't figure out how the "extra space" on the evaluation board, for additional components, is connected to the evaluation board? So far I've come to the conclusion that ground is connected to one of the copper lines and 3.3 V is connected to another.

Are there any other connection that I should be aware of?


I've attached a picture where I've drawn a red circle for VCC, black for GND and Blue for "is there anything here I should worry about".


Hopefully you'll be able to answer this question


Thank you.
