A mysterious Google device appears to have passed through the FCC yesterday. First noticed by Droid-Life, the product was filed under the FCC ID A4R-GG1 and the filing is incredibly vague when it comes to specific features of the device. While it could be the new Chromecast that is reportedly coming later this year, many of the hints throughout the filling lend credibility the potential of it being a new version of Google Glass.

The device wasn’t categorized like most devices making their way through the FCC and is labeled simply as a Bluetooth device with support for 802.11a/b/g/n/ac WiFi on 2.4GHz and 5GHz bands. While that seems a tad unnecessary for a wearable like Google Glass, the GG1 bit of the model name could very well imply Google Glass.

The mysterious device also carries support for Bluetooth LE and rechargeable, non-removable batteries. In the package is an AC charger and USB cable. Another interesting tidbit disclosed in the FCC filing is the FCC’s Label & Location document, which you access by going to the settings menu, regulatory information, and scrolling left and right to view device e-labels.

There aren’t a many devices that Google itself would be sending through the FCC, especially ones that feature rechargeable batteries and have interface that allows you to scroll left and right in the settings app. Those tidbits don’t exactly make sense for a Chromecast, but definitely do for Google Glass…
