Kinect's slim form factor has forced Microsoft to split up the main board, stacking three boards vertically like a small apartment building.

There's a fan at the far end of the Kinect. It's aligned to suck air in one side of the Kinect and push it out the other.

We've finally found the Kinect's eyes.

Two cameras and an IR projector.

• Left: (IR CMOS) Microsoft / X853750001 / VCA379C7130
• Center: (Color CMOS) VNA38209015
• Right: (IR Projector) OG12 / 0956 / D306 / JG05A

This picture is of the device upside down, so these labels are swapped from what you would see looking at the Kinect.

These are not tiny, cell-phone cameras— they're closer to the camera you might find in a webcam, with large lenses and autofocus.

We can't independently confirm the resolution of the cameras yet, but Microsoft claims that the infrared cam is 320x240 and the RGB cam is 640x480.

This is a Prime Sense diagram explaining how their reference platform works. The Kinect is the first (and only) implementation of this platform.

One camera (and one IR transmitter) provide input for the depth map (rumored to be just 320x240), while the third camera detects the human visual spectrum at 640x480 resolution.

We have heard claims that the system can measure distance within 1cm of accuracy at two meters. While that's great in concept, early reviews are showing that you don't get anywhere near that accuracy in the real world—yet.

All four microphones connect to the motherboard with a single cable connector.

After removing three connectors and seven T10 Torx screws, the top board can be separated from the other two boards.

After heating up the adhesive on the heat sink with a heat gun, a spudger may be used to pry it off the motherboard with little trouble.

The brains of the Kinect. The folks at UBM TechInsights helped us identify many of these chips. You can see a high resolution scan of this board here.

This board features a TI TAS1020B USB audio controller front and center.

A Kionix MEMS KXSD9 accelerometer is probably used for inclination and tilt sensing, and possibly image stabilization. The Kinect also uses this to know if the sensor has been moved externally
