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.

3. Starting with TPM540 EVK
3.1. Hardware preparation and setup
Attach the included antenna to the SMA connectorJ21
Plug-in the included DC adapter to DC Jack J1
Or each UART to USB cable.
Plug-in 3FF SIM card to J17(back side of EVK)
Switch on S2(Power switch) to turn on TPM540.
There is no need to turn on S2 while using USB cable to power up EVK
Figure 3.1
Module PWR1 LED will be lighted when turning on EVK successfully.

3.2. Software preparation and setup
Prepare and install Silicon Lab CP210X UART to USB Driver, Version 6.7
(Please access Silicon Lab website to download driver.)
Prepare Serial Port Terminal Tool (Putty, SecureCRT, Teraterm..etc)
3.3. Starting to access EVK and TPM540
Turn on EVK
Connect UART0 to PC via USB cable.
Setup Terminal tools, please refer figure 3.3
COM port: com port will be enumerated on Windows device manager
Setting Baud rate for UART0: default is 115200.
Figure 3.3 for putty setting.
Opening terminal tools and sending AT command from UART.

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.

5. LED status
5.1. Module_PWR1 LED:
For VCC status indication.
ON: VCC is present.
OFF: VCC is absent.
VCC is provided by 5V to 3.3V LDO.
5.2. Module_LED1:
This LED is controlled by PMU_EXT_ALARM pin, it can be used for alarming an external
host.
TBD
5.3. Module_LED2:
