Connectors and Pinout Table[edit | edit source]

Connectors description[edit | edit source]

In the following table are described all available connectors integrated on AURA SOM:

Connector name Connector Type Notes Carrier board counterpart
J1 SODIMM DDR3 edge connector 204 pin TE Connectivity 2013289-1

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

AURA TOP view
AURA BOTTOM view

Pinout table naming conventions[edit | edit source]

This chapter contains the pinout description of the AURA module, grouped in two tables (odd and even pins) that report the pin mapping of the 204-pin SO-DIMM AURA connector.

Each row in the pinout tables contains the following information:

Pin Reference to the connector pin
Pin Name Pin (signal) name on the AURA connectors
Internal
connections 		Connections to the AURA components
  • CPU.<x> : pin connected to CPU pad named <x>
  • CAN.<x> : pin connected to the CAN transceiver (TI SN65HVD232)
  • PMIC.<x> : pin connected to the Power Manager IC (NXP PCA9451A)
  • LAN.<x> : pin connected to the LAN PHY (Microchip LAN8830T-V)
  • 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

Voltage domains[edit | edit source]

Voltage domain Nominal voltage [V] Notes
3.3VIN 3.3 See Operational_characteristics of the SoM wiki page
NVCC_3V3 3.3 Voltage generated by the internal PSU. See Power Supply Unit (PSU) wiki page
NVCC_GPIO 3.3 Voltage generated by the internal PSU. See Power Supply Unit (PSU) wiki page
VDD_ANA_1V8 1.8
