JNX46 carrier board for autonomous applications for NVIDIA Jetson Orin Nano, Orin NX or Xavier NX

The JNX46 builds on the JNX45. It has not the same form factor.
It has the same form factor to the JNX44. Measurement: 158mmx94,7mm

The JNX46 is populated with additional features compared to the JNX45:

  • Optimizing power supply input circuitry
    • over harting socket (power in)
      optional Molex microfit (power in)
  • External display port
    • 8Kp30
      Integration of display port connector to have the possibility for higher display resolutions
  • additional USB 2.0 with 4 port hub
    • 1.) External USB 2.0 type A connector
      2.) Internal USB 2.0 type A connector: for optional safety boot device (power
          controlled MCU)
      3.) M.2 key E 2242 USB 2.0 only (e.g. GPS cards)
      4.) Mini PCIe slot for LTE cards
  • CR2032 lithium cell for the RTC (not rechargeable)
  • LTE: card: Nano or eSim
  • Service socket
  • Please order Service Port Adapter (38563-2) for flashing and console debugging.

    The JNX46 is a compact carrier board which is optimised for the Jetson Orin Nano and NX. It is based on the JNX45 and adds a 5 port USB 3 hub (10 Gbit/s). It stands out due to the 7 USB 3 ports (2 native plus 5 shared). The JNX46 integrates 12 channels of power consumption measurement. The power consumption of each USB port, the Jetson power rail and the 3.3V rail can be measured.

    With each double USB socket, the power can be switched on and off by software. This allows a power reset on any connected USB peripheral.

    The JNX46 integrates a MCU with 5 UART ports for sophisticated system management functions:
    – Jetson console port (for debugging)
    – Jetson user UART port (for communication between MCU and Jetson)
    – LTE UART (to receive remote system management messages)
    – Wifi UART (for secondary LTE IoT system management)
    – MCU console

    Further the MCU has sufficient flash memory to store multiple console debug logs for remote debugging. Last the MCU can operate as watchdog to the Jetson, to restart the system, when the Jetson becomes unresponsive. A secondary SSD may be installed. Its power is enabled by the MCU if the Jetson is failing to boot from its primary SSD device and if a complete factory reset should be performed. With this the primary SSD may be restored.

    More features

    – 2x M.2 NVME SSD (primary on bottom side – x4, secondary to top side – x1)
    – 2x CSI-2 with 4 lanes each
    – GbE
    – 12V to 30V power input (supports automotive applications with 12V and 24V batteries)

    – service port connector for debugging and flashing (IX connector)
    – power (optional)
    – USB flashing port
    – 2x UARTs (Jetson debug console and MCU console)

    Powering: 3 pin Harting connector (power and power enable)
    GPIO (12 pin Harting): 4 in and 2 out, RS485 (half duplex) and CAN

    M.2 key E 2230/2242: for standard Wifi or LTE IoT cards (Orin: PCIe and USB)
    M.2 key B 3042/3052: for LTE cards (UART to MCU optional)
