A look at Amazon's Echo Dot and the technology they chose. A nicely designed bit of kit!

I think the RFID tag is used for when Amazon pre-configures these devices with your account, they probably store some info on there or on their assembly line and according to that then flash the correct files and all.

Flashing would be too complicated. These devices phone home to Amazon and obtain the necessary configuration at that time.

I have two 2nd gen Dots. I had a 3rd gen but found it sounded like it was emitting sound from under a multiple layered blanket. Even after adjusting the bass, mid-range and treble it still sounded muddy and muffled. I sent it back. Amazon actually called me to get my feedback.

Kindles also have the same type of RFID tag on the back cover - at least the three Kindle Keyboards that I tore down. Must be something common to Amazon, maybe stock keeping?

Please... is it the IDENTICAL DAC chip for both vers2 and vers 3 echo dots ? wish to know if there is a REAL sound upgrade or not...at that level...we use far better ext. amps and spkrs anyway...ALSO, note that amazon UK has echo INPUT... a new thing... PLS LET ME KNOW ABOUT DACs...on both or, at least, in this 3rd vers....thanks...good job

Not a custom chip. It's the ISSI3236A RGB LED driver in 5x5mm QFN. I'm trying to promote the KTD2061 in 3x3mm QFN to replace that chip with about 1/3rd the size and PCB traces. But our schedule couldn't make it happen for Echo gen3. kzread.info/dash/bejne/eHikxMiRg6_Qobg.html

What's that RFID thing going to do that has anything to do with privacy? It doesn't work unless it's excited by an electromagnetic field to power it's circuitry, which means someone with an RFID field generator has to be very close to it, and then it can only receive/send pre-programmed data back. It has no way to record or store voice data on that tiny sand-grain of a chip. And when are you going to let someone with an RFID scanner into your home?

Predecessors? You have to pay pretty close attention during setup to avoid activating Google Assistant or Siri on just about any phone you can still get to hold a battery charge on. Been a thing since Android 6 and iOS 5, and those things have video, audio, location, massive storage, independent data connections, and access to all of your personal information. In comparison to how unnerving a smartphone can be, these barely cross past "cute".
