INTRODUCTION:
This document provides a basic functional and operational description of Global PCBA- NNT-TG05. Operational
instructions, capabilities and hardware features are elaborated. Block diagram and visual references are provided
as a supplement.
PRODUCT OVERVIEW AND IMPACT SUMMARY:
NNT-TG05 is a PCBA that provides features such as location, temperature, vibration, and optic sensing.
Aforementioned features are sampled at pre-designated configurable intervals, and then transmitted in real time
to the customer user interface for observation by our end users. In the event that coverage is unavailable, this
device stores information in logging memory which is subsequently transmitted when coverage is reacquired.
2G(GSM) and 4G (CATM/NBIOT) networks are in the process of being antiquated in various parts of the world. To
adapt to such a changing environment, the latest generation of this Go product was designed to transmit data on
CATM (LTE) and NBIoT network with a 2G as a fallback.
REFERENCES:
Components incorporated in the design of the PCBA- NNT-TG05 product were analyzed for performance during
Research and development. Approved technical documentation was obtained by respective manufacturers.
Additional information provided was based on simulations, electrical circuit design, validation, and real time
observations.

OPERATIONAL INSTRUCTION:
Initialization:
NNT-TG05 is initialized by pulling the tab from the main power switch. Upon initialization, a Blue LED serves as a
“network status indicator”. A brief description of blue LED indicator is bulleted below.
Constant Blue LED illumination: unit is attempting to acquire network.
Blinking LED: Network acquisition successful.
Blue LED disappears several seconds and blinks every 11 seconds after network acquisition is successful.
Tracking:
Information such as device location, temperature, illuminance, and vibration events are all available in real time on
Oversight. If network is unavailable, the unit stores the aforementioned data which is subsequently transmitted
when coverage is reacquired.
Tertiary Power Supplies
The NNT-TG05 does not provide a viable means of providing power for peripherals. Hence voltage regulators
(LDO’s) were introduced. Typical voltage regulator is rated at 1.8 VDC output and is capable of supplying up to 200
mA of current. Our design accommodates interrupts, so there is negligible current draw until the device awakes
for pre-designated sampling or report intervals. A single 2.8V LDO provides bias for LED operation only.
Modem
Quectel BG96MA-128-SGN modem facilitates communication on CATM1, NBIoT and 2G networks. A multi-tuned
antenna also optimizes signal strength dBm (power ratio in Decibels) on all available networks. Increased memory
enhances the logging capability for extended “out of coverage” scenarios. Figure 1 contains a block diagram that
summarizes the design of this product.
Sensor Integration

4
NNT-TG05 contains peripherals that are used to provide invaluable information to the end user. Optic sensing,
temperature, humidity, G force detection and location services are all provided to the end user by a customer User
Interface. The optic sensor provides information regarding changes in illuminance, and also serves as a mean of
security if utilized in a standard environment that is devoid of light. NIST traceable temperature and humidity also
serves as a means of monitoring the ambient environment of the product, and the accelerometer provides
vibration events when configured G (acceleration due to gravity) thresholds are exceeded. Sensor integration is
configured to the BG96 by I2C protocols.
Debug Port
A micro-USB port provides dual functionality to this design. Firstly, it serves as a mean of charging the cells
appended to the device. Secondly, it provides a AT debug interface to the modem. Observe figure 2 for the
location of the micro-USB port and additional components on the main PCB. An additional debug interface is
available by PCI connection.
Firmware:
Firmware architecture enables RAT (Radio Access Technology) handling with CATM1 as the primary mode of data
transmission, NBIoT as secondary and 2G as a fallback mode. However, RAT priorities are interchangeable. If the
network is unavailable, the module is placed in AP Mode (Airplane Mode) for 3 hours, and subsequently re-
attempts network connection after the elapsed AP Mode duration occurs.

Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining
to the OEM the labeling requirements, options and OEM user manual instructions that are required (see
next paragraph).
For a host using a 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 straight forward
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: AMH101019” or “Contains FCC ID: AMH101019” 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.
The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for
unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The
user’s manual or instruction manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment. In cases where the manual is provided only in a
form other than paper, such as on a computer disk or over the Internet, the information required by this
section may be included in the manual in that alternative form, provided the user can reasonably be
