Five LEDs on the phyCORE-OMAP44xx Carrier Board show the status of the different voltage domains.
The assignment of the LEDs to the voltage domains is shown in the following table:
Four jumpers on the phyCORE-OMAP44xx Carrier Board allow to enable, or disable single voltage domains.
Closing a jumper
disables
the corresponding voltage domain. The following table lists the jumpers and the
associated voltage domain.
2.1.3.2.1 Wall Adapter Input (X6)
Permissible input voltage at X6: +12 V to +24 V DC unregulated.
The required current load capacity of the power supply depends on the specific configuration of the phyCORE
mounted on the carrier board, the particular interfaces enabled while executing software as well as whether an
optional expansion board is connected to the carrier board. An adapter with a minimum supply of 2.0 A is
recommended.

It is necessary to ensure that jumper JP5 is open in order to supply power to the phyCORE module!

Caution:
Do not use a laboratory adapter to supply power to the carrier board! Power spikes during power-on could
destroy the phyCORE module mounted on the carrier board! Do not change modules or jumper settings while
the carrier board is supplied with power!
