Snapchat’s corporate parent Snap Inc. may be getting ready to release a new version of its Spectacles wearable device soon: On late Tuesday, the FCC published a new filing made by the company for a “wearable video camera.”

Snap didn’t immediately respond to a request for comment.

The heavily redacted filing is short on details, and for instance doesn’t feature photos or a user manual of the device. However, some of the documents publicly available mention both Spectacles as a device description well as “Model 002” to indicate that it is a second version of the device.

One of the major hardware changes seems to be the support of the 802.11ac Wifi standard, which will support faster file transfers in the 5GHz band. Also notable: Snap’s original Spectacles featured a FCC ID label on the inside of the temples. The new version will instead come with an electronic ID label, accessible within the Snapchat app, which could suggest a redesigned frame.

Cheddar recently reported that Snapchat was working on two new Spectacles versions, including one with smaller improvements over existing hardware and one with a dual camera and GPS that could sell for as much as $300.

Snapchat has had some difficulties selling the original version of Spectacles. Snap CFO Drew Vollero revealed late last year that the company had to write off close to $40 million in unsold inventory and excess purchasing commitments because it had overestimated the demand for the product.
