EVK-G20 - Getting Started

GSM.G1-EK-11002-2 Preliminary Page 2 of 17

1 Starting upEVK-G20 is a powerful and easy to use tool that makes evaluating u-blox LEON data and voice modules simple.

This section describes the main connections and settings required to get started.

Refer to the LEON-G100 / LEON-G200 series Data Sheet [2] and the LEON-G100 / LEON-G200 SystemIntegration Manual[3] for the features supported by LEON-G100 / LEON-G200 series modules.

Figure 2: EVK-G20 block diagram

The EVK-G20 consists of two boards:

the lower one: Evaluation Board EVB-WL1, containing power supply, u-blox GPS/GNSS module, peripherals

the upper one: Adapter Board ADP-G100 (or ADP-G200), where the LEON wireless module is soldered

The two boards are connected by means of Dual-In-Line male Board-to-Board connectors provided on thebottom of the Adapter Board and the corresponding female connectors provided on the top of the lower board:in this way the module interfaces are connected to the peripherals available on the lower board. Wirelessmodule interfaces are available for test purposes (e.g. for the connection to an external application processor) onthe Dual-In-Line male Board-to-Board connectors provided on the top layer of the Adapter Board (J301, J302),which are pin-to-pin compatible with the connectors on the bottom layer of the Adapter Board.
