Nest Protect Teardown

Contributors: Nick Poole

Datasheet Roundup

Here's a list of the datasheets and product pages that I was able to pull together in case you want more information on any of the parts that go into the Protect. Not every device had identifying markings, and, even then, some of them weren't well documented. These should cover most of the more exotic parts, though:

• Freescale Kinetis K60
• Freescale K16
• EM357 ZigBee SoC
• Figaro TGS-5342 CO Sensor
• muRata Type ZX WiFi Module
• Passive IR Sensor

I hope you enjoyed this teardown. This is just another great example of how amazingly inexpensive computers have become. This smoke detector undoubtedly has thousands of times the amount of processing power as the computers that landed us on the moon... And considering my habit of leaving the soldering iron on at home, that's probably a good thing.
