When I was in need of some cameras for a hardware project I thought I'll just use some Raspberry PI cameras and rework the schematic to fit my use case, but then I found out there is very little information out there about the Raspberry PI cameras, software or hardware. I figure its a good start to reverse the PCB. Its a relatively simple circuit with 2 LDOs at 1.8v and 2.8v. A buck regulator putting out 1.2v. What appears to be an I2C memory hanging out. A dual NMOS transistor package used to level convert the I2C bus between 3.3v and 1.8v. A 24 MHz crystal to drive the clock input to the sensor. I'm not sure about the I2C Memory or what exactly the purpose of the inductors on the differential pairs are yet.
You can examine the schematic, PCB and Board photos in more detail using the interactive viewers linked to the buttons below. The schematic includes potential Digikey parts that should work in place of what was there since the chip markings didn't turn anything up in searches. If any one knows what they are let me know.
Below are some photos of the board. Click the board photo viewer button above to examine them in more detail.
Here is the reversed schematic. If anyone notices anything wrong let me know.
