Connectors and Pinout Table[edit | edit source]

Connectors description[edit | edit source]

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 conventions[edit | edit source]

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
  • BT_<x> : pin connected UART bus (Bluetooth)
  • SDIO_<x> : pin connected to the SDIO bus (WiFi)
Ball/pin # Component ball/pin number connected to signal
Voltage I/O voltage levels
Type Pin type:
  • I = Input
  • O = Output
  • D = Differential
  • Z = High impedance
  • S = Power supply voltage
  • G = Ground
  • A = Analog signal
Notes Remarks on special pin characteristics
Pin MUX alternative functions Muxes:
  • Pin ALT-0
  • ...
  • Pin ALT-N

The number of functions depends on platform
