Any idea what HW/MCU is inside Amazon Monitron?

FCC ID from docs page picture:

2AVPL-TE1A001

Search at FCC.gov:

Some of the docs are permanently confidential. And I’m not sure how to pull the others up. Maybe someone with more familiarity of the FCC can pull them.

One caveat: the FCC ID is from a docs page picture. That may not be the actual ID used for in-production items, but it probably is a good bet it is.
