JETSON TX2 DEVELOPER KIT
The NVIDIA® Jetson™ TX2 Developer Kit gives you a fast, easy way to develop software
and hardware for the Jetson TX2 AI supercomputer on a module. Jetson TX2 is ideal for
applications requiring high computational performance in a low power envelope.
NVIDIA JetPack™ SDK supports both your developer kit and host development
platform. It includes:
• Sample Linux filesystem with NVIDIA drivers
• AI and Computer Vision libraries and APIs
• Developer tools
• Documentation and sample code
Before using your developer kit, you must install JetPack. A Linux host computer is
required; for details, see How to Install JetPack
Minimum system requirements for the host computer are:
• Ubuntu Linux x64 v16.04 or v18.04
• A valid Internet connection
• At least 23GB of disk space
, below.
INCLUDED IN THE BOX
The Jetson TX2 Developer Kit includes:
• Jetson TX2 module (P3310) with thermal solution
• Reference carrier board (P2597)
• Power supply with AC cord
• USB Micro-B to USB A cable
• USB Micro-B to Female USB A cable
• (2x) WLAN/Bluetooth antenna

Note about carrier board revisions
The B02 and B04 revision carrier boards are extremely similar. B04 added the CR5 and
CR6 LEDs and some minor circuit changes. The C02 revision included changes in
support of Jetson TX2i and Jetson TX2 4GB modules, consolidation of button header pins
into a single pin header, and changing the SATA connector to a right angle type to avoid
possible conflict with a PCIe card.
See the Jetson TX2 Developer Kit Carrier Board Specification
for comprehensive information.
Interface Details
This list highlights some of the Jetson TX2 Developer Kit carrier board interfaces.
• [CR1] Green LED indicates when SoC is enabled.
• [CR2] Green LED indicates when carrier board is powered.
• [CR3] Green LED indicates when [J18] M.2 Key E connector pin 6 is active.
• [CR4] Green LED indicates when [J18] M.2 Key E connector pin 16 is active.
• [CR5] Red LED indicates when main power supply is connected and active.
• [CR6] Red LED Indicates when the 12V supply for PCIe/SATA is active.
• [J1] SATA connector includes both data and power.
• [J2] PCIe x4 connector routes to a x4 PCIe 2.0 controller.
• [J4] The Power LED header can connect to a remote power LED.
• [J5] 10/100/1000 BASE-T Ethernet.
• [J12] Full-size SD Card interface supports up to SDR104 card mode (UHS-1).
• [J13] 400-pin (8 x 50) connector for the Jetson module. The Jetson TX2 Developer
Kit carrier board supports these Jetson modules: Jetson TX2, Jetson TX2i, Jetson
TX2 4GB, and Jetson TX1. See the L4T Development Guide
software support for those modules.

the developer kit already has thermal solution attached including Delta
Electronics AFB0405MA-AFGE
• [J16] HDMI 2.0.
• [J18] M.2 Key E connector can be used for wireless networking cards, and
includes interfaces for PCIe (x1), USB 2.0, UART, I2S & I2C.
• [J19] USB 3.0 Type A.
• [J20 B02/B04 or J28 C02] USB 2.0 Micro-AB connector.

Two 3.3V power pins and two 5V power pins. These are not switchable;
power is always available when the developer kit is connected to power.
o Interface signal pins.
By default, all interface signal pins are 3.3V, but some can be configured for
1.8V. See [J24] information below.
L4T provides a Python library, Jetson.GPIO, for controlling GPIOs. The
library has the same API as RPi.GPIO. See /opt/nvidia/jetsongpio/doc/README.txt on your Jetson system for details.
By default, all interface signal pins are configured as GPIOs, except pins 3
and 5 and pins 27 and 28, which are I2C SDA and SCL, and pins 8 and 10,
which are UART TX and RX.

• [J22] The camera connector supports up to six directly connected cameras via
CSI-2, or up to 12 cameras via the virtual channel feature of CSI-2. The connector
also includes some interface options for audio (I2S & DMIC).
• [J24] The voltage select header enables either 3.3V or 1.8V for these [J21] 40-pin

The 3.3V level is selected when a jumper is on [J24] pins 1-2. The 1.8V level is
selected when a jumper is on [J24] pins 2-3.
• [J25] Use the included developer kit power supply with this DC power jack.
• [J26] 30-pin expansion header includes:
o Power pins.
