Recently, UBM Tech dismantling report, Microsoft's gaming peripherals, somatosensory Kinect the BOM cost of about $ 57, the main chips from Marvell, Texas Instruments, PrimeSense and STMicroelectronics.



"One of the most important to the number of winners from Israel PrimeSense, the company provided for the Kinect including audio, image processors and video interface."

Kinect front panel consists of four microphones, users can accurately locate. The action is determined by infrared camera. The other two are 16-bit grayscale image sensor 32-bit true color QVGA and VGA.

The cost of 57 dollars, 18 dollars are spent PrimeSense reference design, including microphone, camera and processor.

Microsoft estimates before Christmas, will sell 5.5 million Kinect, for suppliers it really is a joyful thing.
