JNX45 carrier board for autonomous applications for NVIDIA® Jetson Orin Nano™, Orin NX™ or Xavier NX™

The JNX45 is a compact carrier board which is optimised for the Jetson Orin Nano and NX. It is based on the JNX42 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 JNX45 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 JNX45 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.

Please order Service Port Adapter (38563-2) for flashing and console debugging.
