Connectors and Pinout TableEdit
Connectors descriptionEdit
In the following table are described all available connectors integrated on DWS_ADD-ON:
| Connector name | Connector Type | Notes | Carrier board counterpart |
|---|---|---|---|
| J1 | Dual in line low profile high density connector 30pins | Molex 501920-3001 | Molex 52991-030, others are available with different stand-off |
| Antenna's connector | UFL type | N.A. | UFL cable side (many versions available in the market already inserted on cables/antenna patches) |
The dedicated carrier board must mount the mating connector and connect the desired peripheral interfaces according to DWS pinout specifications. See the images below for reference:
Pinout table naming conventionsEdit
This chapter contains the pinout description of the DWS module, grouped in two tables (odd and even pins) that report the pin mapping of the TBD: connector type DWS connector.
Each row in the pinout tables contains the following information:
| Pin | Reference to the connector pin |
| Pin Name | Pin (signal) name on the DWS connectors |
| Internal connections |
Connections to the DWS components
|
| Ball/pin # | Component ball/pin number connected to signal |
| Voltage | I/O voltage levels |
| Type | Pin type:
|
| Notes | Remarks on special pin characteristics |
| Pin MUX alternative functions | Muxes:
The number of functions depends on platform |
