The ConnectCore 9M 2443 development board implements two user buttons and two
user LEDs in addition to those provided on the module. The user LEDs on the
development board can be enabled or disabled by correctly setting jumper J5 and
J6. The table below shows which S3C22443 GPIO is available for implementing the
user interface.
Both push-buttons can also be used for wake-up functions.
User buttons can also be used as a wake-up event for power management modes.
The user LEDs on the development board can be enabled or disabled by correctly
setting J5/J6.
The integrated on-chip functions of the module are outlined below.

ConnectCore 9M 2443 Development Board is powered by either the main 9-
30VDC power supply or by the PoE (IEEE 802.3af) module near to the Ethernet
connector.
Both power supplies sources can be switched off through one power switch.
From the varying input voltage (9-30VDC), a stable base power supply is
created on the ConnectCore 9M 2443 development board. The 3.3VDC power
supply is provided to the module, where other power supplies can be
generated.
The ConnectCore 9M 2443 module supports another external power source:
VLIO. This power source normally comes from a battery and is used in Mobile
application for generating the S3C2443 core voltage. On the ConnectCore 9M
2443 development board, VLIO is selectable by jumper setting onboard
+3.3VDC, or external VLIO.

Comments
100 Ohm serial resistors should be used to
avoid conflicts with the CPU functions when
the buttons are pushed.
Jumper JP5 as to be set.
