Jetson TX2 Hardware in Jackal

Installation​

note

This page outlines the steps for installing the TX2 hardware in Jackal. See also the instructions for installing the Jetson software.

Step 1: Remove Mini-ITX Computer​

note

Skip this step if you don't have an existing computer.

  1. If you have a Mini-ITX computer installed it will need to be removed. With the computer tray open locate each of the cables connected to the motherboard and hard drive. Remove the power, power switch, USB and SATA cables. The two cable ties can be cut to completely remove the power and SATA cables. The two antenna cables are connected underneath. Keep this in mind for the next steps.

  2. Remove the 4 hex screws from the motherboard using a 2.5 mm wrench. Gently lift it out disconnecting the antenna connectors as you do so.

  3. Remove the cable ties holding the USB header, power switch signal and antenna wire. The Jetson Nano doesn't have a USB header so it will have to be replaced with a USB mini cable. You will need extra slack in both the antennae cables and power switch signal as well.

  4. Remove the SSD from the outside of the computer tray.

Step 2: Install the TX2​

  1. Install the Jetson TX2 using M3 screws or the screws removed from the computer. The holes will only line up in one orientation.

  2. Plug a USB mini cable from the Jetson to the Jackal MCU board. This is beside where the USB header was removed if you had a computer. We recommend using a USB hub to increase the number of connected devices.

  3. Plug the power switch cable into the power switch header (J6).

  4. If you wish to use the antenna cables attached to the Jackal, remove the U.FL connectors from the Jetson module and connect the antenna cables.

    caution

    Take your time with this step as the UF.L connectors are fragile. If you wish not to disconnect the UF.L cables you can replace the antenna mounts on the Jackal with SMA extensions.

  5. Make a power cable that connects to the 12 V user power (Molex connector) to a barrel connector with center positive. Refer to the Jackal User Manual for the pinout of the user power.

    danger

    Do NOT plug this into the ITX power plug on the power distribution board.
