2) Wake-up PIN is used to wake-up the module when it enter low power mode, please
3) Mode-IN PIN is used to switch module between pure data mode & command mode,
4) TX-IND PIN is used to control the time delay before Module send data to MCU. Please
5) UART_RX/UART_TX, need add pull-up resister accordingly, suggest to reserve.
6) P1 is the FW download port, please reserve if the PCB space is enough.

Please be noticed following information and instructions
The MODEL STB1132 has been granted as limited modular approval for mobile applications.
MODEL STB1132 must be installed in the designated host as specified in this manual.
2. The MODEL STB1132 and its antenna must not be co-located or operating in conjunction with any other
transmitter or antenna within a host device. This equipment complies with FCC RF radiation exposure limits
set forth for an uncontrolled environment.
3. A label must be affixed to the outside of the end product into which the MODEL STB1132 module is
incorporated, with a statement similar to the following: For MODEL STB1132: This device contains FCC ID:
2AJ22STB1132.
4. The module shall be in non-detachable construction protection into the finished products, so that the end-user
has to destroy the module while remove or install it.
5. This module is to be installed only in mobile or fixed applications. According to FCC part 2.1091(b) definition
of mobile and fixed devices is:.
iTON Technology Corp. STB1132-25
should be placed in the end-user’s operating manual
1. Separate approval is required for all other operating configurations, including portable configurations with
respect to 2.1093 and different antenna configurations.
Mobile device:
A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to
generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between
the transmitter’s radiating structure(s) and the body of the user or nearby persons. In this context, the term ‘‘fixed
location’’ means that the device is physically secured at one location and is not able to be easily moved to another
location.
Portable device:
For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the
radiating structure(s) of the device is/are within 20 centimeters of the body of the user.

6. Separate approval is required for all other operating configurations, including portable configurations with
iTON Technology Corp. STB1132-25
respect to FCC Part 2.1093 and different antenna configurations.
7. A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently
affixed label, the module must be labelled with an FCC ID: 2AJ22STB1132. The OEM manual must provide
clear instructions explaining to the OEM the labelling requirements, options and OEM user manual instructions that
are required
For a host using a this FCC certified modular with a standard fixed label, if (1) the module’s FCC ID is not
visible when installed in the host, or (2) if the host is marketed so that end users do not have
straightforward commonly used methods for access to remove the module so that the FCC ID of
the module is visible; then an additional permanent label referring to the enclosed module:
“Contains Transmitter Module FCC ID: 2AJ22STB1132” or “Contains FCC ID: 2AJ22STB1132” must
be used. The host OEM user manual must also contain clear instructions on how end users can
find and/or access the module and the FCC ID.
8. Host product is required to comply with all applicable FCC equipment authorizations regulations,
requirements and equipment functions not associated with the transmitter module portion. compliance must be
demonstrated to regulations for other transmitter components within the host product; to requirements for
unintentional radiators (Part 15B). To ensure compliance with all non-transmitter functions the host manufacturer
is responsible for ensuring compliance with the module(s) installed and fully operational. If a host was previously
authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter
certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module
is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements.
Since this may depend on the details of how the module is integrated with the host, we suggest the host device to
recertify part 15B to ensure complete compliance with FCC requirement: Part 2 Subpart J Equipment Authorization
Procedures , KDB784748 D01 v07, and KDB 997198 about importation of radio frequency devices into the United
States.

FCC Certification Requirement:
The end product with an embedded - MODEL STB1132 may also need to pass the FCC Part 15
unintentional emission testing requirements and be properly authorized per FCC Part 15.
Note: If this module is intended for use in a portable device, you are responsible for separate
approval to satisfy the SAR requirements of FCC Part 2.1093.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications made to this equipment not expressly approved by iTon Technology Corp.
may void the FCC authorization to operate this equipment.
