Note that this setup will not always work because the power consumption of the entire board can be
higher than what a PC/laptop can provide. This might also be true for a powered USB hub.
The 12V supply input is needed when running USB Host application that require powering external
USB devices.

ESD Precaution
Please note that the
iMX RT1176 uCOM Board
and
uCOM Carrier Board
come
without any case/box and all components are exposed for finger touches – and
therefore extra attention must be paid to ESD (electrostatic discharge)
precaution.
Make it a habit always to first touch the metal surface of one of the USB,
SD or Ethernet connectors for a few seconds with both hands before
touching any other parts of the boards.
That way, you will have the same
potential as the board and therefore minimize the risk for ESD.
Never touch directly on the
iMX RT1176 uCOM Board
and in general as little as possible on the
uCOM
Carrier Board
. The push-buttons on the
uCOM Carrier Board
have grounded shields to minimize the
effect of ESD.
Note that Embedded Artists does not replace boards that have been damaged by ESD.

General Handling Care
Handle the
iMX RT1176 uCOM Board
and
uCOM Carrier Board
with care. The boards are not
mounted in a protective case/box and are not designed for rough physical handling. Connectors can
wear out after excessive use. The
uCOM Carrier Board
is designed for prototyping use, and not for
integration into an end-product.
Also handle the
iMX RT1176 uCOM board
with great mechanical care. Only unmount it from the
uCOM Carrier board
if absolutely needed. Only use small movements and small force. Do not insert a
screwdriver between the uCOM board and
uCOM Carrier board
and bend without having first watched
