Product Features and Specifications
Describe
The TG7120-16 module is designed based on the Bluetooth 5.0 chip TG7120B.
It is a Bluetooth wireless communication module that realizes ultra-low power
consumption Internet of Things. The Bluetooth chip in the module is equipped
with an ultra- low power consumption CK802 32-bit processor, equipped with
512KB/256KB Flash and 64KB SRAM, featuring ultra-low power consumption, high
performance and wireless multi-mode. The TG7120-16 module design includes the
peripheral basic circuit of the Bluetooth chip, and the module is designed as
a mail hole interface, which is very convenient for customers to design and
use.
The module supports low-power Bluetooth 5.0 features, and provides rich
hardware interfaces including UART, PWM, ADC, SPI, GPIO, etc., enabling simple
and fast access to the Tall Genie ecosystem.

Module Application Notes
Layout Precautions
“ANT AREA” Clearance is required and wiring is prohibited, it is best to hollow out this part
- The module power supply filter capacitor should be as close as possible to the module VDD signal interface
- Try not to take the power supply or other strong signal lines at the bottom of the module
- P9,P10, GND,VDD The four signals are the interfaces for downloading and debugging the module, and test points need to be reserved

FCC STATEMENT
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.
Warning: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
NOTE: 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 Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20mm between the radiator & your body.
Integration instructions for host product manufacturers according to KDB
996369 D03 OEM Manual v01
2.2 List of applicable FCC rules
FCC Part 15 Subpart C 15.247 & 15.207 & 15.209
2.3 Specific operational use conditions
Operation Frequency:2402~2480MHz
Number of Channel:40 Channels
Modulation Type: GFSK
Antenna Type: PCB antenna
Antenna Gain(Peak):1.57 dBi (Provided by customer)
The module can be used for mobile or portable applications with a maximum
1.57dBi antenna. The host manufacturer installing this module into their
product must ensure that the final composite product complies with the FCC
requirements by a technical assessment or evaluation to the FCC 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.
2.4 Limited module procedures
Not applicable. The module is a Single module and complies with the
requirement of FCC Part 15.212.
2.5 Trace antenna designs
Not applicable. The module has its own antenna, and doesn’t need a host’s
printed board microstrip trace antenna etc.
2.6 RF exposure considerations
The module must be installed in the host equipment such that at least 20mm 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 or new
application. The FCC ID 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 authorization.
2.7 Antennas
Antenna Specification are as follows:
Antenna Type: PCB antenna
Antenna Gain(Peak):1.57 dBi (Provided by customer)
This device is intended only for host manufacturers 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. The antenna must be either
permanently attached or employ a ‘unique’ antenna coupler.
As long as the conditions above are met, further transmitter test will not be
required. However, the host manufacturer 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.).
2.8 Label and compliance information
Host product manufacturers need to provide a physical or e-label stating
“Contains FCC ID VYV-TG7120B-16 With their finished product.
2.9 Information on test modes and additional testing requirements
Operation Frequency:2402~2480MHz
Number of Channel:40 Channels
Modulation Type: GFSK
Antenna Type: PCB antenna
Antenna Gain(Peak):1.57 dBi (Provided by customer)
Host manufacturer must perform 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.
2.10 Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for FCC Part 15 Subpart C
15.247 & 15.207 & 15.209 and that the host product manufacturer is responsible
for compliance to any other FCC 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 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
compliance testing with the modular transmitter installed.
