At the heart of Google Glass is an OMAP 4430 processor by Texas Instruments, supported by 2 gigabytes of SDRAM and 16 gigabytes of NAND flash.
Back in December 2011, the first hints appeared that Google was developing wearable glasses. By April 2012, Google Glass made their first appearance when Sergey Brin wore a prototype to the Foundation Fighting Blindness event in San Francisco. Finally, in April 2014, Google made a version available to customers for wider testing.
At the heart of Google Glass is an OMAP 4430 processor by Texas Instruments. It is supported by 2 gigabytes of SDRAM and 16 gigabytes of NAND flash, a WiFi/Bluetooth module, and a five-megapixel camera. Powering it all is a 570 mAh Li-Polymer battery.
The OMAP 4430 architecture observed in our teardown is presently an end-of-life/obsolete solution from Texas Instruments. This hints at a long development time and suggests that Google or Foxconn made a large parts purchase, or they are planning a limited product run of this generation. If Google is planning a second-generation Glass product, it will likely be based on a processor by Intel, NVidia, or Qualcomm.
With a "special Tuesday" price of $1,500 and a bill of materials of less than $100, it appears that Google is making a fortune from each sale, but given the long development cycle and its associated costs, Google is likely to be much closer to a small profit or loss or break-even.
