Cat-M1/NB1 Module
1. Introduction
1.1. Document Purpose
The purpose of this document is to introduce TPM540 EVK and to provide a design reference.
EVK also enables users to make a prototype on TPM540 platform which resembles the actual
target during the design and build phases of a project. It makes the design efforts of a user
simple, cost-effective and fast. Various interfaces which is included on the board make the
development board ideal for a wide variety of applications. The EVK leverages the capability of
the TPM540 LTE Cat. M1 cellular module and provides access to a variety of interfaces including
UART, USB, USIM.

4. Button introduce
4.1. RECOVERY button:
This button is used to enter boot ROM mode for firmware upgrade and recovery system
when device cannot boot up by some reason.
Please visit Sercomm technical support website and issue a ticket when you have problem
with boot up your TPM540.
4.2. WAKEUP button:
This button is connecting to PMU_WAKEUP ping and used to wakeup TPM540 while device is
under power saving mode.
When there is no traffic, TPM540 will get into power saving mode immediately and TPM540
cannot receive and deal any commands from host. Please push the button to wakeup
module and send AT commands.
4.3. RESET button:
This button is connecting to PMU_SHUTDOWN pin for initiating power cycle that resets the
device or shutdowns device. (For reset function, please pull low button at least 100ms)
4.4. STATUS button:
This button is connecting to PMU_POWER_BUTTON pin and it can be used to either go into
power down mode when device is awake or waking up the device from low power mode.
While PMU_SHUTDOWN and PMU_WAKEUP cause an immediate action,
PMU_POWER_BUTTON reaction is not immediate and involves SW response.

8. Federal Communication Commission Interference Statement
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.
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 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 Caution:
Any changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
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 20cm between the radiator &
your body.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
and
2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 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
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID can not 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
www.sercomm.com DOC-669671v1 13
TPM540 EVK

obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such
that 20 cm may be maintained between the antenna and users. The final end product must be labeled
in a visible area with the following: “Contains FCC ID: P27-TPM540”. The grantee's FCC ID can be
used only when all FCC compliance requirements are met.
Manual Information To the End User
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.
This module can only be used with a host antenna circuit trace layout design in strict compliance with
the OEM instructions provided.
