NVIDIA Jetson TX1/TX2 Developer Kit
Carrier Board
Abstract
This document contains recommendations and guidelines for Engineers to follow to create modules for the expansion
connectors on the Jetson™ carrier board as well as understand the capabilities of the other dedicated interface
connectors and associated power solutions on the platform.
Note:
Jetson TX2 utilizes Tegra X2 which is a Parker series SoC.
CAUTION:
1. ALWAYS CONNECT JETSON MODULE & ALL EXTERNAL PERIPHERAL DEVICES BEFORE
CONNECTING THE POWER SUPPLY TO THE AC POWER JACK. Connecting a device while powered
on may damage the Developer Kit carrier board, Jetson module or peripheral device. In addition,
the carrier board should be powered down and the power removed before plugging or unplugging
devices or add-on modules into the headers. Wait for the red power VDD_IN LED (See Figure 1)
to turn off, or wait for 5 minutes if your system does not have a power LED. This includes the
Jetson module, the camera & display headers, the M.2 connector, the PCIe® x4 connector, SATA
& the other expansion headers. For the PCIex4 & SATA connector, also wait for the PCIe/SATA
12V LED to turn off (See Figure 1)
2. The NVIDIA® Jetson 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 carrier board.
NVIDIA will not replace units that have been damaged due to ESD discharge.

1.0 INTRODUCTION
The NVIDIA® Jetson carrier board is ideal for software development within the Linux environment. Standard connectors are
used to access Jetson module 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 module device, supporting documentation, and code samples to help you get
started.
