1.1 EVK-G45 overview
The EVK-G45 kit is a powerful and easy-to-use tool that simplifies evaluation of u-blox SARA-G450
GSM/GPRS modules.
This section describes the main connections and settings required to get started.
☞See the SARA-G4 series Data Sheet [3] and the SARA-G4 series System Integration Manual [4] for
the features supported by the u-blox SARA-G4 series cellular modules.

Figure 2: Block diagram of EVK-G45
The EVK-G45 is formed by three boards:
The lower one, called EVB-WL3, contains the power supply and other peripherals for the
SARA-G450 cellular module (as SIM card holder, headset jack, power-off button and power-on
button).
The cellular adapter board, called ADP-G450, contains the SARA-G450 cellular module, the cellular
antenna connector, a switch for the digital I/O interfaces (GDI) voltage selection, and a USB
connector for the UART AUX interface.
The GNSS adapter board, called ADP-GNSS, contains the u-blox GNSS module, the LDO supply
regulator, 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 board and their corresponding female connectors provided on top of the lower
board.
The cellular module’s interfaces are available on the dual in-line male board-to-board connectors
provided on the top layer of the cellular adapter board (J0403 / J0404), which are pin-to-pin
compatible to the connectors on the bottom layer of the adapter board.
The lower board (EVB-WL3) is designed also to be used with other u-blox cellular adapter boards. It
contains additional switches, jumpers, connectors, LEDs and parts that are only partially described in
Figure 1 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.

⚠CAUTION! IN THE UNLIKELY EVENT OF A FAILURE IN THE INTERNAL PROTECTION CIRCUITRY,
THERE IS A RISK OF AN EXPLOSION WHEN CHARGING A FULLY OR PARTIALLY DISCHARGED
BATTERY. REPLACE THE BATTERY WHEN IT NO LONGER HAS A SUFFICIENT CHARGE FOR
UNIT OPERATION. CONTROL THE BATTERY BEFORE USE IF THE DEVICE HAS NOT BEEN USED
FOR AN EXTENDED PERIOD OF TIME.
⚠CAUTION! RISK OF EXPLOSION IF BATTERY IS REPLACED WITH AN INCORRECT TYPE. DISPOSE
OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS!

1.7 Software installation
The USB drivers are available with the EVK-G45. Executable files can be downloaded from
www.u-blox.com/evk-search 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.
