The following is a list of connections on the IGX Orin Board.

The Orin Module is installed in a 699-pin socket (J27). If there is a reason to remove or replace the module, see the following instructions.

The BMC Module card is installed in the card socket at J36. In addition, there is a UART for accessing the BMC Module device, which is located at J51. For more information, see BMC Module.

BMC Module UART Header

A UART for accessing the BMC Module device is located at J51.

The following table details the J42 pin description.

Front Panel and Power Button Header J42 Pin Descriptions


  1. CVM (IGX Module) present. The signal will be low when module is fully inserted. CVM_PRSNT0 and PRSNT1 pins are shorted on the module and at opposite corners of the module. CVM_PRSNT connects to PRSNT1. PRSNT0 is tied to GND.

  2. The SYS_RST_IN_N_KEY signal is driven by the IGX Module during power ON. The signal is used as a system reset. The signal can be asserted (low) to reset the IGX Module SoC and boot related devices on the module. This will reset the system but will not result in a full power cycle.

  3. BUTTON_POWER_ON_N is used to power the system on, off or to place the system in standby or bring it out of standby:

    • System OFF: Asserting signal powers the system ON

    • System ON: Momentary assertion of the signal places system in standby.

    • System ON but in standby: Momentary assertion of the signal brings system out of standby.

    • System ON: Asserting signal >4 seconds but < 10 seconds initiates software shutdown of the system.

    • System ON: Asserting signal > 10 seconds initiates hardware shutdown of the system.

Force Recovery Button

The IGX Module supports a USB Recovery mode that can be used for flashing the device as well as for debug purposes. To enter USB Recovery mode, the Force Recovery button must be held low during power-on. This can be accomplished by holding button S1 down during power-on.

The IGX Orin Board supports several USB connections.

  • J6/J7 (USB Type A USB 3.2 and USB 2.0 stacked connectors)

  • J52 (USB Type C connector).

  • J62/J63 (Front USB headers).

USB 3.2 Type A Stacked Connectors

Each of the connectors at J6 and J7 support two USB Type A USB 3.2 and USB 2.0 connectors in a stacked configuration below an RJ45 connector. These are located on the back of the motherboard and protrude through the back panel.


Figure 7‑1. USB 3.2 Type A Ports - Back Panel

USB 3.2 Type C Connector

This connector supports USB 3.2 and USB 2.0. Both interfaces come from the IGX Module through muxes. USB 3.2 uses the module UPHY_RX1/TX1_P/N pins for USB 3.2. A mux is used to connect the interface to both RX1/TX1_P/N and RX2/TX2_P/N interfaces on the connector. The USB 2.0 interface comes from the IGX Module USB0_P/N pins through a mux. The mux can select to pass these to the USB Type C connector or to the BMC Module card socket. This USB 2.0 interface supports USB Recovery mode on the IGX Module.

Front USB Headers

These two headers are intended for supporting additional USB 3.2 and USB 2.0 connectors on the front of the system using cables. Each are 20-pin, 2 mm pitch connectors (Pin 20 is removed for keying purposes).

The IGX Orin Board provides 100 GbE QSFP28 ports (J18 and J19) and two 1 GbE RJ45 ports (J6 and J7) on the rear panel. The 1 GbE ports are each part of a stacked connector with USB x2 at the bottom and an RJ45 at the top. The two 100 GbE QSFP ports are also located on the back panel as shown in the following figure. Each port has four channels, and each channel is capable of up to 25GbE speeds. This provides a total of 100GbE if all four channels are used simultaneously.


Figure 7‑4. QSFP and RJ45 Ports – Back Panel

Two PCIe x16 slots are provided (Slot 0 – J29 and Slot 2 – J30). These support PCIe Gen5. For Slot 0 (J29), only the lower eight lanes are used. All 16 lanes are supported on Slot 2 (J30).


Figure 7‑5. PCIe Slots

There are two stacked SATA connectors (J57 and J58). Each stack has two SATA 4 connectors. These are located at the front of the motherboard as shown in the following figure.

The CAN bus is a low-speed bus 2-wire multi-drop bus capable to have more than 100 nodes on the same bus with multiple bus initiators. The bus supports data rates pf 1 Mbps (CAN) or 5 Mbps (CAN FD). When multiple messages are transmitted at the same time, the higher priority node wins, and the lower priority one will have to retransmit the message.

On the development system, headers are implemented to bring out multiple IGX Module and Aurix MCU CAN ports.
