Figure 3: Block diagram of EVK-L2 for TOBY-L2 product versions "01" (top) and "02" / "62" onwards (bottom)
The EVK-L2 is formed by three boards:
The lower one, called EVB-WL3, contains the power supply and other peripherals for the TOBY-L2 series
cellular module (SIM card holder, Reset button and Power-on button).
The cellular adapter board, called ADP-L2, contains the TOBY-L2 series cellular module, the cellular antenna
connectors and the USB connector for the cellular module. It also contains the u-blox ELLA-W1 series Wi-Fi
module, the Wi-Fi antenna connector and an audio codec for product versions "02" / "62" onwards.
The GNSS adapter board, called ADP-GNSS, contains the u-blox GNSS module, the GNSS antenna connector
and the USB connector for the GNSS module.
The boards are connected by means of male header board-to-board connectors provided on the bottom of the
adapter boards and their corresponding female connectors provided on top of the lower board.
The USB interface of the cellular module is available on the native USB connector on the cellular adapter board,
while the other peripherals are available on the Dual-In-Line male Board-to-Board connectors provided on the
top layer of the cellular Adapter Board (J300 / J301 or J200 / J201), which are pin-to-pin compatible to the
connectors on the bottom layer of the adapter board.
The lower board (EVB-WL3) is designed to also be used with other u-blox cellular adapter boards. It contains
additional switches, jumpers, connectors, LEDs and parts that are partially described in Figure 1, Figure 2 or in
this document, because they are intended for use only with other u-blox cellular modules. It is recommended to
leave any additional connector unconnected, and to leave any additional switch in its default configuration.

The USB drivers are available with the EVK-L2. Executable files can be downloaded from www.u-blox.com/evk-
downloads and saved to any location on the computer hard drive. The installation can be started by running the
executable file on a computer with the Windows operating system.

1.8 Board setup
1. Insert a SIM card into the SIM card holder (J300 on the EVB).
2. Connect a cellular antenna provided with the evaluation kit box to the Primary cellular antenna SMA
connector on the ADP-L2 (ANT1, RF input/output for transmission and reception of LTE/3G/2G RF signals).
3. Connect a cellular antenna provided with the evaluation kit box to the Secondary cellular antenna SMA
connector on the ADP-L2 (ANT2, RF input for the reception of the LTE RF signals as per the Down-Link
MIMO 2 x 2 and for the reception of the 3G RF signals as per the Down-Link Rx diversity). Place the
secondary cellular antenna far enough from the primary cellular antenna (should be more than 20 cm).
4. If the Wi-Fi functionality is required, connect the Wi-Fi antenna provided with the evaluation kit box to the
Wi-Fi antenna SMA connector on the ADP-L2 (ANT WL). Place the Wi-Fi antenna far enough from the
cellular antennas (should be more than 20 cm).
Wi-Fi functionality is available on the EVK-L2 for TOBY-L2 modules product versions "02", "62" onwards
5. If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit box to the
GNSS antenna SMA connector on the EVB. Place the GNSS antenna in a location with good sky view.
Interface to the GNSS module is not supported by TOBY-L2 modules4.
6. Connect the AC / DC +12 V power adapter provided with the evaluation kit box to 9 –18 V Power Input
connector (J400 on the EVB). LED DL401 lights blue.
7. Be sure to provide a jumper socket on the Cellular VCC supply jumper (J404 on the EVB). This provides
the connection from the 3.8 V output of the supply circuit on the EVB to the VCC input of the module.
8. To enable the board power supply, turn the Main power switch (SW400 on the EVB) to the ON position.
LED DL400 lights green. The cellular module switches on.
9. For communication via USB, connect the USB cable to the Cellular native USB connector (J100 on ADP).
LED DS100 on ADP lights blue. After the end of the module boot, the following devices are by default
enabled with Windows (details as the ports numbering can be seen via the Windows Device Manager)5:
oModems u-blox Composite USB Modem Interface
AT commands interface is available over this modem COM port
oNetwork adapters Remote NDIS based Internet Sharing Device
Ethernet-over-USB connection is available over this network adapter
Run an AT terminal application (e.g. the u-blox m-center tool) selecting the u-blox Composite USB Modem
Interface COM port, with these settings:
oData rate: 115200 b/s
oData bits: 8
oParity: N
oStop bits: 1
oFlow control: HW
See Appendix A for how to configure the u-blox m-center AT terminal for Windows.
4Supply for the GNSS module can be provided mounting the 0R jumper R106 and removing the 0R jumper R107 on the ADP-GNSS.
5A message of “driver installation fail” may appear on Windows if the USB cable has been connected before the end of the module boot,
but this can be ignored as the normal operating functionality of the module will be anyway available after the end of the module boot.

10. For communication via the TOBY-L2 module’s UART interface, the following connections are allowed and
can be alternatively enabled in a mutually exclusive way (see Table 8 for switch position and LED status):
a. Connect a USB cable to mini USB connector (Cellular USB, J501 on EVB), LED DL501 lights blue
b. Connect an RS232 cable to DB9 connector (Cellular RS232, J500 on EVB)
When a USB cable is connected to the mini USB connector, two COM ports are enabled in Windows (the
numbering of the COM ports can be seen via the Windows Device Manager). The serial port for AT
commands is available over the first numbered COM port opened by the driver.

AT+CPWROFF
OK
Switch off the EVK-L2.
The external Maxim MAX9860 audio codec mounted on the
EVK-L2 will be fed by the 13 MHz master clock provided by
the GPIO6 and it will be dynamically programmed over I2C
interface at any subsequent re-boot of the module and every
time audio path is enabled, providing voice capability at the
headset jack connector of the EVK-L2.
1.13 Switching off the EVK-L2
To switch off the EVK-L2, send the +CPWROFF AT command. Make sure to use this command before switching
off the main power, otherwise settings and configuration parameters may not be saved on the EVK-L2.

ASetting up AT terminal applications for
communication with EVK-L2
The u-blox m-center cellular module evaluation tool is a powerful platform for evaluating, configuring and
testing u-blox cellular products. m-center includes an AT commands terminal for communication with the device
and can be downloaded free-of-charge from our website (http://www.u-blox.com).
1. Follow the board setup instructions in section 1.8 to provide all the required connections and switching on
the cellular module.
2. Run the m-center tool: after the m-center start-up, the Home page appears.
3. On the Home page, set up the AT COM port; for
the setting values see section 1.8.
Check with the Windows Device Manager to find
out which COM port is being used by EVK-L2.
Figure 4: “Home” page
4. Enable the connection to u-blox cellular module by
clicking on the Connect button.
5. Retrieve the module and network information by
clicking on the Get Info button.
6. The module information is retrieved and displayed
on Home page.
7. Click on the AT Terminal button, found at the
upper right of the Home page. A new window
opens and the AT-command terminal is now ready
for communication with EVK-L2.

This section describes how to set up the EVK-L2 for browsing the internet with Windows 7 operating system on
a PC connected with the EVK-L2 over the USB physical interface of the TOBY-L2 series module. Follow the board
setup instructions described in section 1.8 in order to provide communication via the USB interface of the
TOBY-L2 series module. Then use the AT terminal (see appendix A) to enter the following AT command lines:
1. Perform the following procedure to activate an external PDP context with the preferred APN:
