Front I/O

  1. Power button and power indicator LED

    The power button allows the user to turn the device on and off. The power indicator LED notifies the user that the device is operational and the compute module is working.

  2. USB Type-A 3.0 port

    This Type-A SuperSpeed-compatible port can be used with any USB peripheral. As it is directly routed to the SoC, it is the fastest available USB port (performance up to 5 Gbps).

  3. USB Type-B micro for console

    This port can be used for entering a debug console conveniently when neither a display/keyboard/mouse nor SSH access over the network is available.

  4. General-purpose LEDs

    These LEDs can be configured in the operating system or user’s application for custom functions.

  5. Nano-SIM card tray & NXP UUU interface

    This SIM card cover hides a Nano-SIM card slot as well as another USB Type-B micro port for a low-level NXP debug interface. The programming interface can be used to recover the device using the NXP UUU utility.

Rear I/O

  1. 2x USB Type-A 2.0 ports

    These two Type-A High-Speed-compatible ports can be used with any USB peripheral.

  2. Terminal block for industrial I/O

    Based on the configuration of your gateway, you may have access to one or more galvanically isolated industrial I/O ports (RS-232, RS-485, CAN, and digital GPIO) over this terminal block. For more information on interacting with this port and the configuration of your device, please refer to the Industrial I/O (Example of a subsection within Industrial I/O) section.

  3. Locking DC barrel jack for power input

    The device is primarily powered by an unregulated 8 V - 36 V power supply through this standard 3.5 mm DC jack. The centre pin polarity is negative (+: shell; -: centre pin). A built-in mechanism allows for twist-action locking of the jack in order to prevent accidental unplugging.

  4. Ethernet (ETH2) RJ-45 interface with optional Power over Ethernet (PoE)

    This standard RJ-45 connector provides a 1 Gbps Ethernet interface. Additionally, depending on the configuration of your gateway, this port is able to support 802.3af Type-I Power over Ethernet (PoE) supply.

  5. DVI-D over HDMI

    This physical HDMI connector outputs a DVI-D (DVI-Digital) signal that can be interpreted by HDMI-compliant monitors. It supports a resolution and refresh rate of up to 1080p60.

  6. Ethernet (ETH1) RJ-45 interface

    This standard RJ-45 connector provides a 1 Gbps Ethernet interface.
