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:

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
