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 AUX UART 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.
