Alternative Powering
The board is normally powered from a PC/laptop via the included USB cable (micro-B to A cable) when
connected to position 1) in Figure 1 above. This setup will work in most cases. However note that not
all PC/laptops can provide the needed current. A powered USB hub can be used in this case or an
external power supply.
A separate power supply is always needed in stand-alone situations or when running USB Host
application that require powering external USB devices. If USB Host is not used (or used with very low
external current consumption), a 5V DC/1 Amp power supply (5W) is all what is needed. If USB Host is
used with high external current consumption a 5V DC/2-2.5 Amp power supply (10-12.5W) is needed.
A 2.1mm standard power plug is used to interface the board. Center position is the positive terminal.
It is possible to have both the USB cable and external powering connected to the board at the same
time but only one of them will be used at any time. Powering selector, J29, selects 5V DC
powering via J1 or USB powering via J22. See Figure 8 below where to locate J29.

ESD Precaution
Please note that the
iMX RT1062 OEM Board
and
iMX OEM 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 RT1062 OEM Board
and in general as little as possible on the
iMX
OEM Carrier Board
. The push-buttons on the
iMX OEM 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.
