If you use the FCC's OET search for equipment authorization, you can get
the full non-confidential parts of the application, and it's for a
module, not a chipset.

https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm
note that the grantee code is 2AC7Z and the product code is -ESP8266X
The "-" is part of the product code, the FCC is very literal in their
interpretation of the information companies submit in their applications
:)

And it's a different module than the AIThinker module mentioned earlier
in this thread. That one has its own modular certification.

Both of them have modular approval, allowing them to be used in products
without needing further certification, but there are certain
constraints, the high points being that the module must have an RF
shield and a voltage regulator on the RF output stage. Also for the
containing product to be exempt from certification there must be no
other RF transmitters in the product that contains the module. So if you
were to put a wifi module and a bluetooth module into a product, you
would need to get the product certified, even if both had modular
approval.
