2A64W-ESP32WROOM32E User Manual
1. Applicable FCC rules
This module is granted Single Modular Approval. This module complies to the requirements of FCC Part 15C,
section 15.247.
2. Operational use conditions
This module is only to be used within Volk VistaView, the Class A ophthalmic camera. The input voltage to
the module is nominally 3.0V DC. The operational ambient temperature of the module is -30 to 85 degrees C.
Only the PCB antenna included in ESP32WROOM32E is permitted. Another other external antenna is
prohibited.
3. RF exposure considerations
To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this transmitter must be
installed such that a minimum separation distance of 5mm is maintained between the radiating element
(antenna) & any user’s or bystander at all times.
4. Antenna
Antenna type: PCB antenna
Peak gain: 3.40dBi
5. Label and compliance information
The module must be properly labelled with the text “FCC ID: 2A64W-ESP32WROOM32E”
The FCC ID e-label for the module must be retrievable by the user per requirements outlined in KDB 784749
D02.
The physical temporary label must include the text “Contains FCC ID: 2A64W-ESP32WROOM32E”
The following note must be included in the IFU for the VistaView (Class A device):
Note: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his expense.
6. Information on test modes and additional testing requirements
a) The modular transmitter has been fully tested by original module grantee (Espressif, grantee
code 2AC7Z) on the required number of channels, modulation types, and modes. It should not
be necessary for the host installer to re-test all the available transmitter modes or settings. It is
recommended that the host product manufacturer (the installer of the modular transmitter)
perform some investigative measurements to confirm that the resulting composite system does
not exceed the spurious emissions limits or band edge limits.
