Chapter 1. Introduction
This specification contains recommendations and guidelines for engineers to follow to create
modules for the expansion connectors on the NVIDIA® Jetson AGX Xavier™ carrier board as
well as understand the capabilities of the other dedicated interface connectors and associated
power solutions on the platform.
! CAUTION: ALWAYS CONNECT THE JETSON AGX XAVIER AND ALL EXTERNAL PERIPHERAL
DEVICES BEFORE CONNECTING THE POWER SUPPLY TO THE AC POWER JACK OR TYPE C
CONNECTOR.
The Jetson AGX Xavier Developer Kit carrier board contains ESD-sensitive parts. Always use
appropriate anti-static and grounding techniques when working with the system. Failure to do so
can result in ESD discharge to sensitive pins, and irreparably damage your Jetson AGX Xavier
carrier board. NVIDIA will not replace units that have been damaged due to ESD discharge.
The Jetson AGX Xavier carrier board is ideal for software development within the Linux
environment. Standard connectors are used to access Jetson AGX Xavier features and
interfaces, enabling a highly flexible and extensible development platform. Go to
https://developer.nvidia.com/embedded-computing or contact your NVIDIA representative for
access to software updates and the developer SDK supporting the OS image and host
development platform that you want to use. The developer SDK includes an OS image that you
will load onto your Jetson AGX Xavier device, supporting documentation, and code samples to
help you get started.
