1 Functional description
1.1 Overview
The TOBY-L2 series comprises LTE/3G/2G multi-mode modules in the very small LGA form-factor (35.6 x
24.8 mm) that are easy to integrate in compact designs.
TOBY-L2 series modules support up to six LTE bands, five UMTS/DC-HSPA+ bands and four GSM/(E)GPRS bands
for voice and/or data transmission.
TOBY-L2 series modules are form-factor compatible with the other popular u-blox cellular module families: this
allows customers to take the maximum advantage of their hardware and software investments, and provides
very short time-to-market.
With LTE category 4 data rates at up to 150 Mb/s (downlink) and 50 Mb/s (uplink), the modules are ideal for
applications requiring the highest data-rates and high-speed internet access. TOBY-L2 series modules are the
perfect choice for consumer fixed-wireless terminals, mobile routers and gateways, and applications requiring
video streaming. They are also optimally suited for industrial (M2M) applications, such as remote access to video
cameras, digital signage, telehealth, and security and surveillance systems.

are supported via AT commands.
HTTP6, HTTPS5
Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol (SSL encryption) functionalities are
supported via AT commands. HEAD, GET, POST, DELETE and PUT operations are available.
GNSS via modem5
Full access to u-blox positioning chips and modules is available through a dedicated DDC (I2C) interface. This means
that from any host processor a single serial port can control the cellular module and the positioning chip or module.
For more details see the GNSS Implementation Application Note [5].
Embedded AssistNow
Software5
Embedded AssistNow Online and AssistNow Offline clients are available to provide better GNSS performance and
faster Time-to-First-Fix. An AT command can enable / disable the clients.
CellLocate®5
Enables the estimation of device position based on the parameters of the mobile network cells visible to the specific
device based on the CellLocate® database:
Normal scan: only the parameters of the visible home network cells are sent
Deep scan: the parameters of all surrounding cells of all mobile operators are sent
CellLocate® is available via a set of AT commands for CellLocate® service configuration and position request.
Hybrid Positioning5
The current module position is provided by a u-blox positioning chip or module or the estimated position from
CellLocate® depending on which method provides the best and fastest solution according to the user configuration.
Hybrid positioning is available via a set of AT commands that allow the configuration and the position request.
Wi-Fi via modem7
Full access to u-blox short range communication Wi-Fi modules is available through a dedicated SDIO interface.
This means that from any host processor a single serial port can control the cellular module and the short range
communication module.
All the management software for the Wi-Fi module operations runs inside the cellular module in addition to those
required for cellular-only operation: Wi-Fi driver, Web User Interface (WebUI), Connection Config Manager.
For more details see the Wi-Fi / Cellular Integration Application Note [8].
Firmware update Over
AT commands (FOAT)
Firmware module update over AT command interfaces (UART, USB).
The feature can be enabled and configured through the +UFWUPD AT command.

Feature
Description
Smart Temperature
Supervisor8
Constant monitoring of the module board temperature:
Warning notification when the temperature approaches an upper or lower predefined threshold
Shutdown notified and forced when the temperature value is outside the specified range (shutdown
suspended in case of an emergency call in progress)
The Smart Temperature Supervisor feature can be enabled and configured through the +USTS AT command.
The sensor measures board temperature, which can differ from ambient temperature.
SIM Access Profile (SAP)8
Allows access and use of a remote SIM card/chip instead of the local SIM card/chip directly connected to the
module SIM interface. The module acts as an SAP client establishing a connection and performing data exchange to
an SAP server directly connected to the remote SIM.
The modules provide a dedicated USB SAP channel and dedicated multiplexer SAP channel over UART for
communication with the remote SIM card.
In-Band Modem8
In-Band modem solution for eCall and ERA-GLONASS emergency call applications over cellular networks
implemented according to the 3GPP TS 26.267 specification [13]
When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency call carrying both voice and
data (including vehicle position data) directly to the nearest Public Safety Answering Point (PSAP) to determine
whether rescue services should be dispatched to the known position.
Power saving
The power saving configuration is by default disabled, but it can be enabled and configured using the +UPSV AT
command. When the power saving is enabled, the module automatically enters the low power idle-mode whenever
possible, reducing current consumption.
During idle-mode, the module processor core runs with the RTC 32 kHz reference clock, which is generated by the
internal 32 kHz oscillator.
SMS via IMS9
Allows SMS via embedded IP Multimedia Subsystem
Table 3: TOBY-L2 series main supported features
u-blox is extremely mindful of user privacy. When a position is sent to the CellLocate® server u-blox is
unable to track the SIM used or the specific device.

Page 11 of 47
2 Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
TOBY-L2 series modules must be supplied through the VCC pins by a DC power supply. Voltage must be stable,
because during operation the current drawn from VCC can vary significantly, based on the power consumption
profile of the LTE/3G/2G technologies (described in the TOBY-L2 / MPCI-L2 series System Integration Manual [2]).
2.1.2 RTC supply input / output (V_BCKP)
When VCC voltage is within the valid operating range, the internal Power Management Unit (PMU) supplies the
Real Time Clock (RTC) and the same supply voltage is available on the V_BCKP pin. If the VCC voltage is under
the minimum operating limit (e.g. during not powered mode), the V_BCKP pin can externally supply the RTC.
2.1.3 Generic digital interfaces supply output (V_INT)
TOBY-L2 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when
the module is switched on. The same voltage domain is used internally to supply the generic digital interfaces of
the modules. The V_INT supply output can be used in place of an external discrete regulator.
2.2 Antenna interfaces
2.2.1 Antenna RF interfaces
The modules have two RF pins with a characteristic impedance of 50 . The primary antenna pin (ANT1)
supports both Tx and Rx, providing the main antenna interface, while the secondary antenna pin (ANT2)
supports Rx only for the LTE MIMO 2x2 and 3G Rx diversity configurations.
2.2.2 Antenna detection
The antenna detection is not supported by “00”, “01” and “50” product versions.
The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by TOBY-L2
modules to sense the antenna presence (as an optional feature). It evaluates the resistance from ANT1 and
ANT2 pins to GND by means of an external antenna detection circuit implemented on the application board.
(For more details, see the TOBY-L2 / MPCI-L2 series System Integration Manual [2] and the u-blox AT Commands
Manual [1].)
2.3 System functions
2.3.1 Module power-on
TOBY-L2 series can be switched on in one of the following ways:
Rising edge on the VCC pin to a valid voltage for module supply, i.e. applying module supply
Low level on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time period
when the applied VCC voltage is within the valid operating range (see section 4.2.8). The PWR_ON line
should be driven by open drain, open collector or contact switch.
TOBY-L2 series - Data Sheet
UBX-13004573 - R07 Objective Specification Interfaces
Page 12 of 47
Low level on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time period
when the applied VCC voltage is within the valid operating range (see section 4.2.9). The RESET_N line
should be driven by open drain, open collector or contact switch.
RTC alarm, i.e. pre-programmed scheduled time by AT+CALA command
2.3.2 Module power-off
TOBY-L2 series can be properly switched off by:
AT+CPWROFF command (see the u-blox AT Commands Manual [1]). The current parameter settings are
saved in the module’s non-volatile memory and a proper network detach is performed.
An abrupt under-voltage shutdown occurs on TOBY-L2 series modules when the VCC supply is removed. If this
occurs, it is not possible to store the current parameter settings in the module’s non-volatile memory or to
perform the proper network detach.
An abrupt shutdown occurs on TOBY-L2 series modules when a low level is applied on the RESET_N pin, which
is normally set high by an internal pull-up, for a valid time period (see the section 4.2.9). This causes an abrupt
shutdown of the module: the current parameter settings are not saved in the module’s non-volatile memory and
a proper network detach is not performed.
An over-temperature or an under-temperature shutdown occurs on TOBY-L2 modules when the temperature
measured within the cellular module reaches the dangerous area, if the optional Smart Temperature Supervisor
feature is enabled and configured by the dedicated AT command. For more details see the TOBY-L2 / MPCI-L2
series System Integration Manual [2] and the u-blox AT Commands Manual [1], +USTS AT command.
Smart Temperature Supervisor is not supported by “00”, “01” and “50” product versions.
2.3.3 Module reset
TOBY-L2 series modules can be reset (rebooted) by:
AT+CFUN command (see the u-blox AT Commands Manual [1]). This causes an “internal” or “software”
reset of the module. The current parameter settings are saved in the module’s non-volatile memory and a
proper network detach is performed.
An abrupt “external” or “hardware” reset occurs when a low level is applied to the RESET_N pin, which is
normally set high by an internal pull-up, for a valid time period (see the section 4.2.9). This causes an “external”
or “hardware” reset of the module. The current parameter settings are not saved in the module’s non-volatile
memory and a proper network detach is not performed. The RESET_N line should be driven by open drain, open
collector or contact switch.
2.3.4 Module configuration selection by host processor
The selection of the module configuration by the host application processor over HOST_SELECT0 and
HOST_SELECT1 pins is not supported by “00”, “01” and “50” product versions.
TOBY-L2 series modules include two input pins (HOST_SELECT0, HOST_SELECT1) for the selection of the
module configuration by the host application processor.

2.4 SIM
2.4.1 SIM interface
A SIM card interface is provided on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins: the high-speed SIM/ME
interface is implemented as well as the automatic detection of the required SIM supporting voltage.
Both 1.8 V and 3 V SIM types are supported (1.8 V and 3 V ME). Activation and deactivation with automatic
voltage switch from 1.8 V to 3 V is implemented, according to ISO-IEC 7816-3 specifications. The SIM driver
supports the PPS procedure for baud-rate selection, according to the values proposed by the SIM card/chip.
2.4.2 SIM detection
The SIM detection is not supported by “00”, “01” and “50” product versions.
TOBY-L2 series modules provide the SIM detection function over GPIO to sense the SIM card physical presence
(as an optional feature) when the specific GPIO pin of the module is properly connected to the mechanical
switch of the SIM car holder (for more details see the TOBY-L2 / MPCI-L2 series System Integration Manual [2]).
2.5 Serial communication
TOBY-L2 series provides the following serial communication interfaces:
UART interface: asynchronous serial interface available for the communication with a DTE host application
processor (AT commands, data communication, FW update by means of FOAT) and for diagnostic
USB interface: High-Speed USB 2.0 compliant interface available for the communication with a USB host
application processor (AT commands, data communication, FW update by means of the FOAT feature), for
FW update by means of the u-blox EasyFlash tool and for diagnostic
DDC interface: I2C bus compatible interface available for the communication with u-blox GNSS positioning
chips/modules and with external I2C devices as an audio codec
SDIO interface: Secure Digital Input Output interface available for the communication with an external Wi-Fi
chip or module
2.5.1 UART interface
The UART interface is not supported by TOBY-L200-00S and TOBY-L210-00S modules versions.
The DTR, DSR and DCD signals are not supported by TOBY-L200-50S, TOBY-L210-50S modules versions.
TOBY-L2 series modules include a 9-wire unbalanced asynchronous serial interface (UART) for communication
with an application host processor (AT commands, data communication, FW update by means of the FOAT
feature) and for diagnostic purpose.
UART features are:
Complete serial port with RS-232 functionality conforming to the ITU-T V.24 Recommendation [17], with
CMOS compatible signal levels (0 V for low data bit or ON state and 1.8 V for high data bit or OFF state)
Data lines (RXD as output, TXD as input), hardware flow control lines (CTS as output, RTS as input), modem
status and control lines (DTR as input, DSR as output, DCD as output, RI as output) are provided
Hardware flow control (default value), software flow control, or none flow control are supported
Software flow control is not supported by “00”, “01” and “50” module product versions.
TOBY-L2 series - Data Sheet
UBX-13004573 - R07 Objective Specification Interfaces
Page 14 of 47
Power saving indication available on the hardware flow control output (CTS line): the line is driven to the
OFF state when the module is not prepared to accept data by the UART interface
Power saving control over the RTS input or the DSR input can be enabled via AT+UPSV command (for more
details see u-blox AT Commands Manual [1] and TOBY-L2 / MPCI-L2 series System Integration Manual [2])
The following baud rates are supported: 9600, 19200, 38400, 57600, 115200 (default baud rate when
autobauding is disabled or not supported), 230400, 460800 and 921600 b/s
One-shot autobauding is supported and it is by default enabled: automatic baud rate detection is performed
only once, at module start up. After the detection, the module works at the fixed baud rate (the detected
one) and the baud rate can only be changed via AT command (see u-blox AT Commands Manual [1], +IPR).
The automatic baud rate recognition (autobauding) is not supported by “50” module product version.
Frame format can be:
o 8N2 (8 data bits, no parity, 2 stop bits)
o 8N1 (8 data bits, no parity, 1 stop bit), default frame configuration
o 8E1 (8 data bits, even parity, 1 stop bit)
o 8O1 (8 data bits, odd parity, 1 stop bit)
o 7N2 (7 data bits, no parity, 2 stop bits)
o 7N1 (7 data bits, no parity, 1 stop bit)
o 7E1 (7 data bits, even parity, 1 stop bit)
o 7O1 (7 data bits, odd parity, 1 stop bit)
Automatic frame format recognition is not supported by “00”, “01” and “50” module product versions.
UART serial interface can be conveniently configured through AT commands. For more details see the u-blox AT
Commands Manual [1] (+IPR, +ICF, +IFC, &K, \Q, +UPSV AT command) and TOBY-L2 / MPCI-L2 series System
Integration Manual [2].
2.5.1.1 Multiplexer protocol
The GNSS tunneling and the SIM Access Profile (SAP) multiplexer virtual channels are not supported by
“00”, “01” and “50” modules product version.
TOBY-L2 series modules include multiplexer functionality as per 3GPP TS 27.010 [12] on the UART physical link.
This is a data link protocol which uses HDLC-like framing and operates between the module (DCE) and the
application processor (DTE), allowing a number of simultaneous sessions over the physical link (UART): the user
can concurrently use AT interface on one MUX channel and data communication on another MUX channel.
The following virtual channels are defined (for more details, see the Mux Implementation Application Note [6]):
Channel 0: control
Channel 1 – 5: AT commands / data connection
Channel 6: GNSS tunneling
Channel 7: SIM Access Profile (SAP)
TOBY-L2 series - Data Sheet
UBX-13004573 - R07 Objective Specification Interfaces
Page 15 of 47
2.5.2 USB interface
TOBY-L2 series modules include a high-speed USB 2.0 compliant interface with maximum 480 Mb/s data rate,
representing the main interface for transferring high speed data with a host application processor. The module
itself acts as a USB device and can be connected to any USB host equipped with compatible drivers.
The USB_D+ / USB_D- lines carry the USB data and signaling, providing all the functionalities for the bus
attachment, configuration, enumeration, suspension or remote wakeup according to USB 2.0 specification [18].
The additional VUSB_DET input is available as an optional feature to sense the host VBUS voltage (5.0 V typical).
The VUSB_DET functionality is not supported by “00”, “01” and “50” product versions: the pin should
be left unconnected or it should not be driven high by any external device, because a high logic level
applied to the pin will represent a module switch-on event (additional to the ones listed in section 2.3.1)
and will prevent reaching the minimum possible consumption with power saving enabled.
TOBY-L2 series modules provide by default the following set of USB functions:
CDC-ACM modem: AT commands interface is available over this modem COM port
RNDIS network adapter: Ethernet-over-USB connection is available over this network adapter
The USB of TOBY-L2 series modules can be configured by the AT+UUSBCONF command to select different sets
of USB functions available in a mutually exclusive way. The configured USB profile can thus consist of a specific
set of functions with various capabilities and purposes, such as:
CDC-ACM for AT commands and data
CDC-ACM for GNSS tunneling
CDC-ACM for SIM Access Profile (SAP)
CDC-ACM for diagnostic
RNDIS for Ethernet-over-USB
CDC-ECM for Ethernet-over-USB
CDC-NCM for Ethernet-over-USB
MBIM for Ethernet-over-USB
CDC-ACM for GNSS tunneling, CDC-ACM for SIM Access Profile (SAP), CDC-NCM and MBIM are not
supported by “00”, “01” and “50” product versions.
For more details regarding the USB configurations and capabilities, see the TOBY-L2 / MPCI-L2 series System
Integration Manual [2] and the u-blox AT Commands Manual [1], +UUSBCONF AT command.
USB drivers are available for the following operating system platforms:
Windows Vista
Windows 7
Windows 8
Windows 8.1
Windows Embedded Compact 7
TOBY-L2 series modules are compatible with standard Linux/Android USB kernel drivers.

2.5.3 DDC (I2C) interface
The DDC (I2C) interface is not supported by “00”, “01” and “50” product versions.
TOBY-L2 series modules include an I2C-bus compatible DDC interface (SDA, SCL) available to communicate with
a u-blox GNSS receiver and with external I2C devices as an audio codec: the TOBY-L2 module acts as an I2C
master which can communicate with I2C slaves in accordance with the I2C bus specifications [19].
For more details regarding the DDC (I2C) interface usage and the integration with a u-blox GNSS receiver see the
TOBY-L2 / MPCI-L2 series System Integration Manual [2], the GNSS Implementation Application Note [7], and the
I2C and GNSS AT commands description in the u-blox AT Commands Manual [1].

The SDIO interface is not supported by “00”, “01” modules product versions.
TOBY-L2 series modules include a 4-bit Secure Digital Input Output interface (SDIO_D0, SDIO_D1, SDIO_D2,
SDIO_D3, SDIO_CLK, SDIO_CMD) designed to communicate with an external u-blox short range Wi-Fi module:
the TOBY-L2 cellular module acts as an SDIO host controller which can communicate over the SDIO bus with a
compatible u-blox short range Wi-Fi module acting as SDIO device.
The SDIO interface is the only one interface of TOBY-L2 cellular modules available for communication between
the u-blox cellular module and the u-blox short range Wi-Fi module. The AT commands interface is not available
on the SDIO interface of TOBY-L2 series modules.
The SDIO interface supports 50 MHz bus clock frequency, which allows a data throughput of 200 Mb/s.
For more details regarding the SDIO interface usage and the integration with a u-blox Wi-Fi module see the
TOBY-L2 / MPCI-L2 series System Integration Manual [2], the Wi-Fi / Cellular Integration Application Note [8],
and the Wi-Fi AT commands description in the u-blox AT Commands Manual [1].
2.6 Audio
Audio is not supported by “00”, “01” and “50” product versions.
TOBY-L2 series modules include a 4-wire I2S digital audio interface (I2S_TXD, I2S_RXD, I2S_CLK, I2S_WA) that
can be configured by AT command to transfer digital audio data with an external device as an audio codec.
For more details regarding the I2S digital audio interface usage and the integration with an external digital audio
device as an audio codec see the TOBY-L2 / MPCI-L2 series System Integration Manual [2] and the audio AT

4 Electrical specifications
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating
section may cause permanent damage. These are stress ratings only. Operating the module at
these or at any conditions other than those specified in the Operating Conditions sections
(section 4.2) of the specification should be avoided. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
Operating condition ranges define those limits within which the functionality of the device is guaranteed.
Where application information is given, it is advisory only and does not form part of the specification.

4.3 Parameters for ATEX applications
This section provides useful parameters and information to integrate TOBY-L2 series modules in applications
intended for use in areas with potentially explosive atmospheres (ATEX), describing:
Total internal capacitance and inductance of TOBY-L2 series modules (see Table 25)
Maximum RF output power and voltage at the antenna pin of TOBY-L2 series modules (see Table 26)
Any specific applicable requirement for the implementation of the apparatus integrating TOBY-L2 series
modules, intended for use in potentially explosive atmospheres, must be fulfilled according to the exact
applicable standards: check the detailed requisites on the pertinent normative for the application, as for
example the IEC 60079-0 [20], IEC 60079-11 [21], IEC 60079-26 [22] standards.
The certification of the application device that integrates a TOBY-L2 series module and the compliance of
the application device with all the applicable certification schemes, directives and standards required for
use in potentially explosive atmospheres are the sole responsibility of the application device manufacturer.
Table 25 describes the maximum total internal capacitance and the maximum total internal inductance,

7.2 Moisture Sensitivity Levels
TOBY-L2 series modules are Moisture Sensitive Devices (MSD) in accordance to the IPC/JEDEC
specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. TOBY-L2 series
modules are rated at MSL level 4. For more information regarding moisture sensitivity levels, labeling, storage
and drying see the u-blox Package Information Guide [9].
For MSL standard see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).
7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see TOBY-L2 / MPCI-L2 series System
Integration Manual [2]).
Failure to observe these recommendations can result in severe damage to the device!
7.4 ESD precautions
TOBY-L2 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling TOBY-L2 series modules without proper ESD protection may
destroy or damage them permanently.
TOBY-L2 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD precautions typically
applied to ESD sensitive components.
Table 7 reports the maximum ESD ratings of the TOBY-L2 series modules.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling and
operation of any application that incorporates TOBY-L2 series module.
ESD precautions should be implemented on the application board where the module is mounted, as described in
the TOBY-L2 / MPCI-L2 series System Integration Manual [2].
Failure to observe these recommendations can result in severe damage to the device!
