ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any circuit
board assemblies including Connect Tech carrier
assemblies, it is recommended that ESD safety
precautions be observed. ESD safe best practices include,
but are not limited to:
Leaving circuit boards in their antistatic packaging
until they are ready to be installed.
Using a grounded wrist strap when handling circuit
boards, at a minimum you should touch a grounded
metal object to dissipate any static charge that may be
present on you.
Only handling circuit boards in ESD safe areas, which
may include ESD floor and table mats, wrist strap
stations and ESD safe lab coats.
Avoiding handling circuit boards in carpeted areas.
Try to handle the board by the edges, avoiding contact
with components.

Cogswell hardware Revision E and onward will have increased bandwidth for multiple camera streams. This is due
to CTI moving to an alternate Ethernet Chipset (Intel I210 series), the previous revisions A through D have been
found to have bandwidth limitations due to the ARM Linux4Tegra Ethernet drivers associated with the Intel 82574.

Mini-PCIe/mSATA Slots
The Cogswell Carrier has a single Mini-PCIe and a single mSATA slot. These slots can accept a Mini-PCIe
module or an mSATA SSD module respectively. The Mini-PCIe slot contains a USB 2.0 link as per the Mini-
PCIe specification.
Half and Full Length Mini-PCIe/mSATA Module Installation
The Cogswell Carrier is designed with mounting holes to allow for the population of full length modules. To
install a half-length module you must use a Mini-PCIe Half to Full Size Extension Bracket.

USB 2.0 OTG and USB 2.0
The NVIDIA®Jetson™ Modules have a single USB 2.0 OTG Port that doubles as a regular USB 2.0 Port. On
the Cogswell, this Port is connected to a MUX to allow for both of these functions.
NOTE: Please note that you cannot use both the USB 2.0 OTG Micro-AB Connector and the USB 2.0 Type A
Connector at the same time.

USB 2.0 OTG Client Mode and USB MUX
To put the Cogswell 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. Once in Client Mode, the Cogswell will connect the OTG USB
2.0 Link to the Micro-AB Connector and disable the USB 2.0 Type A connector using the onboard USB MUX.
At this point the Cogswell can be connected to a Host PC for software image flashing. Please refer to the
Software / BSP section of the Manual for instructions on how to do this.

USB 3.0/2.0
The maximum configuration for a NVIDIA®Jetson™ Module allows for one external USB 3.0 Port with an
integrated USB 2.0 Port. The USB 3.0 signals are sourced from different locations on the Jetson™ TX2, TX2i
or TX1 Modules. Use SW2A to select which Module is installed to correctly configure the on-board MUX
which will link the Module to the Cogswell USB 3.0 re-driver and connector.
Over current protection, power supply filtering and ESD protection is provided on-board.
NOTE: Please note that USB3.0 support is NOT natively supported by the stock L4T builds. For USB3.0
support users must deploy CTI-L4T BSP
