Google Glass running on TI's OMAP 4430 chip
Google Glass made its first appearance when Sergey Brin wore a prototype to the Foundation Fighting Blindness event in San Francisco back in April 2012. Two years later, the search giant 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 this 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 ($79.78 for a 16GB version), 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.
