ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Connect Tech
COM Express 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.

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 OTG – Client Mode (Used for Image Flashing)
To put the USB OTG port into CLIENT mode, the USB ID pin needs to be tied to GND. Most USB Micro-B
cables will do this internally. Once in Client mode this port can then be connected to a Host PC. This is
required for software image flashing. Please see the Software Section of this manual for more details.

Switch Designator
Description
SW1
Power Button
-When Orbitty is in “ATX Mode” a button press will initiate boot-
up sequence
-When Orbitty is ON, a button press will initiate a power down
sequence in the Operating System
-When Orbitty is ON and button is held for 5 seconds the system
will do a hard power off (power down ungracefully)
Note: Due to the changes done to the PMIC circuitry of the TX2i Jetson
Module the Orbitty Carrier will always remain ON when in AT (Automatic
Power ON) and ATX (Push Power button) modes. This will cause the
Orbitty Carrier to automatically power ON when voltage is applied to the
system. The system will in addition be unable to shut down in software
(Soft Shutdown), due to the characteristics of the TX2i power circuitry as
such the system will perform a Reset/Reboot function.
SW3
Reset Button
-When button is pressed the system will initiate a Reset sequence
SW2
Recovery Button
-Use this button to perform the Force Recovery Procedure
detailed in the Software Section of this manual.
-This is required when flashing a new image onto the TX2/TX2i
module via the USB OTB port.
