<section begin="Body" /> ==Integration guide==This section provides useful information and resources that let the system designer integrate the DWM module in the application very quickly. === Typical scenario=== The following picture shows the conceptual block diagram of the application where the host is an Embedded PC.

== Hardware versioning and tracking=Electrical guidelines===*Keep SDIO lines as short as possible.*5V and 3.3V rails can power up in any order*Keep WIFI_EN asserted during power-up sequence

===Calibration process===The radio interface of the DWM SOM implements well established versioning and tracking mechanismsmodule is configured by several parameters. These parameters are set through a calibration process, that is described in detail [http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Calibration_Process here].
