Connectors and Pinout TableEdit

Connectors descriptionEdit

In the following table are described all available connectors integrated on DWM_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 marked already inserted on cables/antenna patches)

The dedicated carrier board must mount the mating connector and connect the desired peripheral interfaces according to DWM pinout specifications. See the images below for reference:

 
DWM TOP view with antenna's connector
 
DWM BOTTOM view with main connector


Pinout table naming conventionsEdit

This chapter contains the pinout description of the DWM module, grouped in two tables (odd and even pins) that report the pin mapping of the TBD: connector type DWM connector.

Each row in the pinout tables contains the following information:

Pin Reference to the connector pin
Pin Name Pin (signal) name on the DWM connectors
Internal
connections 		Connections to the DWM components
  • CPU.<x> : pin connected to CPU pad named <x>
  • CAN.<x> : pin connected to the CAN transceiver (manufacturer part number)
  • PMIC.<x> : pin connected to the Power Manager IC (manufacturer part number)
  • LAN.<x> : pin connected to the LAN PHY (manufacturer part number)
  • NOR.<x>: pin connected to the flash NOR
  • SV.<x>: pin connected to voltage supervisor
  • MTR: pin connected to voltage monitors
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
