General Description
Introduction
S28 is a highly integrated wireless module with voice & audio functions. It is
based on BES2600 solution which features a Cortex-M33 Star dual-core MCU
subsystem and a Cortex-A7 dual-core
AP subsystem. Both MCU and AP subsystem are able to run RTOS and user
applications, and the crystal of X1(24MHz) provides the clock.
The module supports low power Wi-Fi 4 ( 1×1 802. 11a/b/g/n dual-band) and
Bluetooth 5.3). Besides, it provides a high-performance on-board printing
antenna to reduce the complexity of hardware design. S28 also provides a voice
& audio CODEC subsystem and a display subsystem with 2D graphics engine. It
supports MIPI DSI HD display up to HD (720P60), supports MIPI CSI Camera up to
2MPixel, and supports microphone arrays with up to three analog microphones or
six digital microphones for far- field voice application. MCU subsystem runs
Bluetooth upper protocol stack, and AP subsystem and 2 D hardware Graphics
Engine can accelerate GUI & VUI, voice & audio processing and AI tasks.
This compact module is a perfect choice for smart appliance, smart panel,
entrance guard and other smart home applications.

FCC Warning
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
- This device may not cause harmful interference, and (
- This device must accept any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC RF exposure statement
The equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance between 20cm the radiator your body.
IC Caution
Radio Standards Specification RSS-Gen, issue 5
This device contains licence-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science and Economic Development Canada’s licence-exempt
RSS(s). Operation is subject to the following two conditions:
- This device may not cause interference.
- This device must accept any interference, including interference that may cause undesired operation of the device.
RF exposure statement:
The equipment complies with IC Radiation exposure limit set forth for

OEM integration instructions
This device is intended only for OEM integrators under the following
conditions:
The transmitter module may not be co-located with any other transmitter or
antenna. The module shall be only used with the external antenna(s) that has
been originally tested and certified with this module.
As long as the conditions above are met, further transmitter test will not be
required.
However, the OEM integrator is still responsible for testing their end-product
for any additional compliance requirements required with this module installed
(for example, digital device emissions, PC peripheral requirements, etc.).
Validity of using the module certification
In the event that these conditions cannot be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC/IC
authorization for this module in combination with the host equipment is no
longer considered valid and the FCC ID/IC of the module cannot be used on the
final product. In these circumstances, the OEM integrator will be responsible
for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC/IC authorization.
End product labeling
The final end product must be labeled in a visible area with the following:
“Contains Transmitter Module FCC ID: 2BABF-S28. Contains IC: 30828-S28.”
Information that must be placed in the end user manual
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the
end product which integrates this module. The end user manual shall include
all required regulatory information/warning as show in this manual.

The module can be used for mobile or applications with a maximum 1.5dBi
antenna. The host manufacturer installing this module into their product must
ensure that the final composit product complies with the FCC/IC requirements
by a technical assessment or evaluation to the FCC/IC rules, including the
transmitter operation.
The host manufacturer has to be aware not to provide information to the end
user regarding how to install or remove this RF module in the user’s manual of
the end product which integrates this module. The end user manual shall
include all required regulatory information/warning as show in this manual.
Limited module procedures
Not applicable. The module is a Single module and complies with the
requirement of FCC Part 15.212.
Trace antenna designs
Not applicable. The module has its own antenna, and doesn’t need a host’ s
printed board microstrip trace antenna etc.
RF exposure considerations
The module must be installed in the host equipment such that at least 20cm is
maintained between the antenna and users’ body; and if RF exposure statement
or module layout is changed, then the host product manufacturer required to
take responsibility of the module through a change in FCC ID/IC or new
application.
The FCC ID/IC of the module cannot be used on the final product. In these
circumstances, the host manufacturer will be responsible for re-evaluating the
end product (including the transmitter) and obtaining a separate
FCC/IC authorization

Host manufacturer must perfom test of radiated & conducted emission and spurious emission, etc. according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. Only when all the test results of test modes comply with FCC requirements, then the end product can be sold legally.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC/IC authorized for FCC Part 15 Subpart C
15.247 & 15.207 & 15.209 & RSS GEN&RSS 247 and that the host product
manufacturer is responsible for compliance to any other FCC/IC rules that
apply to the host not covered by the modular transmitter grant of
certification. If the grantee markets their product as being Part 15 Subpart
B/RSS GEN compliant (when it also contains unintentional-radiator digital
circuity), then the grantee shall provide a notice stating that the final host
product still requires Part 15 Subpart B/ RSS GEN compliance testing with the
modular transmitter installed.
