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.
Two power LEDs are available on the development board, and indicate:
–

All power LEDs are red.
A 3.0V coin cell should be used on the ConnectCore 9M 2443 development
board for powering the RTC unit on the module.
Measuring the current on the development board allows evaluation of power
needed for various board designs.
A current measuring option is implemented by adding a weak resistor in a
series with the power supply that needs to be measured.
Current measurement values might be performed for 3.3VDC, VLIO and VRTC.
Coin cell battery voltage can also be monitored by adding a jumper between
the coincell and the VRTC power supply on the ConnectCore 9M 2443 module.
A push-button allows manual reset by connecting RSTIN# to ground. The reset
controller is located on the ConnectCore 9M 2443 module.
The module JTAG interface is supported through a 20-pin Multi-ICE JTAG
connector, which is located on the ConnectCore 9M 2443 development board.
This connector supports RTCK signal (optional).
TRST# signal has a 2.2K pull-down resistor on module. This means a debugger
with push-pull output at TRST# is needed and open drain is not working.
The ConnectCore 9M 2443 module provides access to one I²C channel. 4k7 pull-
ups resistors are used on the module for these signals.
I²C signals are accessible on the 1:1 expansion connectors and on the
dedicated I²C header.
The POE connectors support the PoE Application Module.
