Google’s product is rather mysterious; the product is identified as a “Wireless Device” only. It appears to be battery powered – no AC connection – but can be powered by a 5V USB connection and a schematic shows it is connected to a laptop for testing. As mentioned 9to5GoogleThe claim may indicate that it is some kind of Nest device – for example, some Nest cameras use 3.65V rechargeable batteries.

Google said the Pixel 7, Pixel 7 Pro, and Pixel Watch are coming this fall, so whatever this “wireless device” might be, it could be revealed when the company shares more details about these other products. Google did not immediately respond to a request for comment.

We’re more confident with Amazon’s filing, which points to a barely revised version of the company’s premium Echo Studio smart speaker. At first glance, there’s no obvious connection: the new product is vaguely described as a “digital media receiver,” but if you dig deeper, the documentation shows it has an AC power cord that lets you plug it into a wall outlet. and Zigbee, a widely used radio to control smart home products. The app itself doesn’t even look like Amazon – instead, it’s filed by a company with the obscure name of Flake LLC.

But Amazon often uses front companies for FCC filings to keep its products private, and photos of another Flake product submitted to the agency—another “digital media buyer”—match exactly to the Echo Studio. And in a newer app actually saidEcho Studio and this second element are “electrically [sic] same”, except for a different MediaTek wireless chip.

It’s not entirely clear why Amazon is replacing the chip, but it may be doing it to fix supply chain issues, as some other companies have done in the past: Tesla is replacing alternative chips to keep production going, Panic said last year. The Playdate gaming PDA is supposed to use a different CPU in subsequent shipments.

Amazon did not immediately respond to a request for comment. The company usually holds a September event full of device news, but given how minor this change seems, there’s a good chance Amazon won’t say anything about it.
