Introduction

Connect Tech’s Sprocket Carrier for NVIDIA® Jetson™ TX2/TX2i/TX1 is designed to match the NVIDIA Jetson module form factor. The Sprocket’s design includes 1x USB OTG, 1 x4 lane MIPI CSI-2, 2x 3.3V UART, 2x I2C, and 4x GPIO.
This design provides our smallest and lowest profile solution yet. The Sprocket and Jetson TX2, TX2i or TX1 stack can be mounted flat in the smallest of spaces, perfect for space constrained payloads such as that of a drone.

USB OTG
The NVIDIA Jetson TX2/TX2i/TX1 has a single USB 2.0 OTG Port.

Function| USB 2.0 OTG|
---|---|---
Location| P3
Type| Molex Micro-AB USB Connector
P/N| 47589-0001
Mating| Any Micro USB 2.0 Plug

USB OTG – Host Mode
To put the USB OTG port into HOST mode, the USB ID pin needs to be left floating. Most USB Micro-A to Type A (Female) cables will do this internally.
USB 2.0 OTG Client Mode (Used for Image Flashing)
To put the Sprocket into Client Mode, the ID Pin on the Micro-AB Connector needs to be pulled high. Most USB Micro-B Cables will do this internally. Please refer to ‘Force USB Recovery Mode’ under the Software / BSP section of the  Manual for instructions on how to do this. Once in Client Mode, the Sprocket will connect the OTG USB 2.0 Link to the Micro-AB Connector. At this point the Sprocket can be connected to a Host PC for software image flashing.
Power Input
The Sprocket Carrier accepts a single power input to power all on-board devices. A power input range of +12V to +16V is acceptable, while a single +12V input is nominal for operation.
WARNING: Please do not attempt to plug in the NVIDIA’s Development kit power supply which is 19.5V. Doing this will damage the carrier board.

Typical Installation

1. Ensure all external system power supplies are off.

2. Install the Jetson TX2/TX2i/TX1 Module onto the Symtec SEARAY Connector P1. Be sure to follow the manufacturer’s directions for proper installation of mounting hardware, heatsink/heat spreader, and any other applicable  requirements from the manufacturer.

3. Install the necessary cables for application. At a minimum these would include:
   a) Power cable to the input power connector
   b) Serial console from the 15 pin I/O cable
   c) Hardware tools like Bus Pirate (https://www.seeedstudio.com/, https://www.adafruit.com/ or for EU customers http://www.watterott.com/) to connect TTL signals from Sprocket to USB port of your computer in order to access  console (Uart0).
   Alternatively, TTL to USB cable like TTL-232R-3V3-WE or similar could be used) can also be used to the emulate the serial console over Putty (or similar opensource serial port emulator) on your PC.
   Note: Serial Console using Bus Pirate:
   Sprocket has been tested working with Bus Pirate v3.6 right out of the box. TX from Sprocket goes to MISO pin on Bus Pirate and RX goes to MOSI pin; finally GND goes to GND.
   Serial Console using TTL (+3.3V) to USB cable:
   TTL to USB serial adapter cable may require an external 5KΩ series resistor to be added between CB251Pin 13 (Uart0-TX) and RXD pin of TTL-232R-3V3-WE. Similarly, may require an external 2KΩ series resistor to be added between CB251-Pin 12 (Uart0-RX) and TXD pin of TTL-232R-3V3-WE.

4. Connect the Power Cable to the Power Supply

5. Switch ON the Power Supply. DO NOT power up your system by plugging in live power.

On-Board Indicator LEDs

The Sprocket Carrier has 3 on-board indicator LEDs.

Software / BSP Details

All Connect Tech NVIDIA Jetson TX2/TX2i/TX1 based products are built upon a modified Linux for Terga (L4T) Device Tree that is specific to each CTI product.
WARNING: The hardware configurations of CTI’s products differ from that of the NVIDIA supplied evaluation kit. Please review the product documentation and install ONLY the appropriate CTI L4T BSPs. Failure to follow this process could result in non-functional hardware.
Connect Tech’s Custom L4T BSP (CTI-L4T)
Connect Tech also offers a custom BSP to add in additional peripheral support on CTI’s Jetson Carrier Boards.
In the case of the Sprocket Carrier Board the CTI-L4T will expose software control of most of the carrier interfaces including MIPI CSI-2, USB and more.
The CTI-L4T can be downloaded directly from Connect Tech here: http://www.connecttech.com/jetson

NVIDIA Jetpack for L4T
The Jetpack for L4T is an on-demand all-in-one package that bundles and installs all software tools required to develop for the NVIDIA’s TX2/TX2i/TX1 Platform with Connect Tech’s TX2/TX2i/TX1 Carrier Boards. Jetpack includes host  and target development tools, APIs and packages (OS images, tools, APIs, middleware, samples, documentation including compiling samples) to enable developers to jump start their development environment for developing with the Jetson Embedded Platform. The latest release of Jetpack runs on an Ubuntu Linux 64-bit host system and supports both the latest Jetson TX2/TX2i/TX1 Development Kit and Jetson TK1 Development Kit.
NVIDIA’s Jetpack can be downloaded directly from NVIDIA here: https://developer.nvidia.com/embedded/jetpack
Force USB Recovery Mode
The Sprocket Carrier does support USB Force Recovery Mode or USB OTG on the USB 2.0 port. To update the firmware on your NVIDIA Jetson TX2/TX2i/TX1, mount the module onto the Sprocket and place the system into USB OTG  Client Mode. This is done by attaching a USB Micro B Cable/Connector to the Sprocket OTG Port. Press and Hold Recovery Button, wait for 5 seconds, while still holding RECOVERY button press for 1 second and release the RESET  button. After this wait for 2 seconds, now you can release the recovery button and the module should now be in recovery mode. From there follow the instructions as detailed in the NVIDIA Jetson TX2/TX2i/TX1 Developer Kit User  Guide or contact support@connecttech.com.

Thermal Details

The Sprocket Carrier Board has an Operating Temperature Range of -40°C to +85°C.
However, it is important to note that the NVIDIA Jetson TX2 and TX1 Modules have its own properties separate to that of the Sprocket Carrier Board. The NVIDIA Jetson TX2i matches the Sprocket Operating Temperature Range of -40°C to +85°C.
Customer responsibility requires proper implementation of a thermal solution that maintains the TX2/TX2i/TX1 SoC and Thermal Transfer Plate (TTP) temperatures below the specified temperatures (shown in the tables below) under  the maximum thermal load and system conditions for their use case.
Jetson TX2i Thermal Specifications

Jetson TX2/TX1 Thermal Specifications

NVIDIA provides complete Thermal Design Guides, which include all of the information required to implement a complete thermal solution for the Jetson TX2, TX2i or TX1 Module. The Thermal Design Guides can be downloaded here:
