iRobot® Create® 3 Hookup Guide for NVIDIA® Jetson™
The iRobot® Create® 3 robot has a USB-C®1 connector implementing a USB 2.0 host capable of 5 V @ 3 A continuous, which can be used to power and communicate with various downstream devices. Here are some hookup examples for NVIDIA® Jetson™2 computers.
NVIDIA® Jetson Nano™ 2GB
The Jetson Nano™ 2GB has a USB-C® port (J2) for power and a USB Micro-B port (J13) for downstream data. This can be connected to the Create 3 robot most simply using a USB-C® hub and two cables -- USB A to Micro-B and USB A to USB-C®.
NVIDIA® Jetson Xavier NX™ Developer Kit
The Jetson Xavier NX™ Developer Kit has a 5.5mm x 2.5mm barrel connector jack (J16) for power (9 V to 20 V) and a USB Micro-B port (J5) for downstream data.
This can be powered from the unregulated battery port of the Create® 3 adapter board by using a JST-XH female connector to DC barrel plug cable. The data connection is established by using a USB Micro B to USB-C® cable.
NVIDIA® Jetson Xavier NX™ Developer Kit Printable Adapter Mount
You can 3d print the mount adapter to place the Jetson Xavier NX Developer Kit in the cargo bay or on the faceplate.
If you are 3d printing the above (mount adapter)[../print_compute/#adapter-mount], use support to support overhang areas.
You need four (4) M3 x 6mm screws; cap head is suggested.
