As it stands I have drawn up a full schematic for the board. I still need to measure the values of the capacitors and inductors but the basic functionality is apparent. There are 3 regulators, 2 LDOs that supply 2.8v and 1.8v and a buck that supplies 1.2v. There is a dual NMOS package that does I2C level conversion from the PIs 3.3v to the 1.8v for the sensor. There is also a 24MHz crystal to drive the clock of the sensor. There is an EVIL I2C cryoto chip used to lock down the Raspberry PI Camera driver so it wont work with cloned boards. Also there are common mode chokes on the differential data pairs.
