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.

Jetson™ TX2, TX2i or TX1 Compatibility
Due to pin-muxing within the Jetson™ TX2, TX2i and TX1 modules, the Elroy Carrier features a DIP switch
setting that will ensure full compatibility depending on which Jetson™ module you use. This DIP switch
setting is only present on board revisions F and later. Elroy Carrier board revisions E and earlier do not offer
full Jetson™ TX2 or TX2i compatibility and this DIP switch setting serves a different purpose on revision E
and earlier. Please see the table below for more information.
To determine which revision of the Elroy Carrier you have please see the revision label as per the image
below.
Function
Jetson™ TX2, TX2i or TX1 Select Switch
Location
SW1 –“H” Switch
Type
DIP Switch
Description
For revisions F and later:
If you are using a Jetson™ TX1 then leave the “H”
switch in the OFF position to ensure full compatibility.
If you are using a Jetson™ TX2/TX2i then leave the “H”
switch in the ON position to ensure full compatibility.
“H” switch OFF = Full Jetson™ TX1 Support
“H” switch ON = Full Jetson™ TX2/TX2i Support
For revision E and earlier:
DIP Switch for Grounding +3.3V_RTC, which will
Ground the VDD_RTC (Pin 50) on the NVIDIA Jetson
Module.
“H” switch ON = connects +3.3V_RTC to ground
For the other switch settings on SW1, please see the
Switch Description section of this document.

Note: This connector can accept cables with contacts facing both up and down. Ensure you are installing the cable
correctly by verifying with the pinout above. Failure to do so may damage the carrier. When installing the cable, the
pins should be facing the PCB, and the white line on the ribbon should face away from the PCB

Mini-PCIe/mSATA Slots
Dual Function Mini-PCIe/mSATA Slots
The Elroy Carrier has a special dual purpose functional Mini-PCIe/mSATA slot (P9). This slot can accept
either a Mini-PCIe module or an mSATA SSD module. This slot has circuitry that allows for the selection
between connecting PCIe lanes or SATA lanes to the Connector. Finally, the slot also contains a USB 2.0 link
as per the Mini-PCIe specification.
See the block diagram for the Mini-PCIe/mSATA switching functionality.
Mini-PCIe/mSATA Switching Functionality Diagram
If a Mini-PCIe Card is placed into the Mini-PCIe/mSATA slot, then the Carrier Control DIP Switch (SW1A)
will select the SATA link routed to the Mini-PCIe/mSATA slot to be disconnected.
If however an mSATA Card is placed into the Mini-PCIe/mSATA slot, then the Carrier Control DIP Switch
(SW1A) will select the PCIe link routed to the Mini-PCIe/mSATA slot to be disconnected.
This allows for the following maximum configurations:
A. 1x Full Sized Mini-PCIe Card, with 0x mSATA Card
B. 2x Half Sized Mini-PCIe Cards, with 0x mSATA Card
C. 1x Half Sized Mini-PCIe Card, with 1x Half Sized mSATA Card
D. 0x Mini-PCIe Card, with 1x Full Sized mSATA Card

NOTE:
The Mini-PCie Card slot at P8 does not have USB2.0 capability, as such when using USB devices over this
interface the Mini-PCIe/mSATA at P9 must be used.

Half and Full Length Mini-PCIe/mSATA Module Installation
The Elroy Carrier is designed with mounting holes to allow for the population of full and half sized modules.
To switch between the sizes, simply move the spacers and screws to the appropriate position. See the images
below for further information.

USB 2.0/3.0
The maximum configuration for a NVIDIA Jetson TX2, TX2i or TX1 Module allows for one external USB 3.0
Port with an integrated USB 2.0 Port. The USB 3.0 signals are sourced from the Jetson TX2/TX2i/TX1
Module, and run through a re-driver.
Over current protection, power supply filtering and ESD protection is provided on-board.

Force USB Recovery Mode
The Elroy carrier supports flashing the TX2/TX2i/TX1 module over USB 2.0 using Port B. A standard
USB-A to USB-A cable is required to connect it to the flashing system. Note that you should leave the
USB cable unplugged until after the TX2/TX2i/TX1 is put into recovery mode.
To flash the TX2/TX2i/TX1, first ensure the unit is powered down. Next, connect pins 6 and 20 of the
System Header together with a jumper wire, then power on the unit. The jumper wire can be removed after
applying power. Connect the USB-A to USB-A cable from a free USB port on the host PC to the USB 2.0
port on the Elroy. The TX2/TX2i/TX11 can now be flashed using the standard NVIDIA flashing tools.
