Assembly of Xavier NX Dev Kit and Waveshare 17855 Jetson Nano Case (C)

The rugged metal case by Waveshare is well suited for the Xavier NX dev kit. A challenge are the Wifi antennas. A Wifi adapter card is already pre-mounted to the Xavier NX dev kit. The Wifi card is a AzureWave CB375NF (status of Feb. 2021). It is located at the bottom side of the Xavier NX carrier board. Two narrow PCB antennas (Wifi + Bluetooth) are connected via short cables providing Hirose U.FL (or similar I-PEX MHF) connectors and glued to the frame on the bottom side.

The RF signal from these antennas would strongly attenuated by the metal case. It is advisable to connect external antennas.

In the part list above we list one example product consisting of two rod antennas mounted on SMA receptables perfectly fitting the dedicated antenna holes in the metal case.

A step-by-step description on how to mount the Jetson Xavier NX to the case and just rearranging the default internal PCB antennas is given here: Jetson Xavier NX case assembly (without external antennas). Thank you, Harley!

Another description how to mount the SMA antennas is here Jetson Xavier NX case assembly (with external antennas).

Additional Components

These components can be used with both development kits, Nano and Xavier NX.

NVIDIA Jetson Nano Developer Kit, rev. B01 (4GB, Dual Camera)

:!: Even if you are using rev. B01 read the Jetson Nano 2GB Developer Kit User Guide (with carrier board rev. A02), too! Most information is still valid, e.g. how to use the FFC connectors for the camera cables. The GPIO pin header definition has not changed neither.

Sources

Most important differences to the A02 version:

  • The Carrier Board version B01 now provides two MIPI CSI-2 camera interfaces for FFC (FFC: Flexible Flat Cable).
  • The barrel connector power jumper is located elsewhere.
  • The compute modules on A02 and B01 are not compatible. You cannot mix modules and carrier board versions.

:!: IMPORTANT: Close the JUMPER J48 if you want to use the barrel connector for power!
