2.2.4.7 Custom Solutions Header (2.0 mm Pitch)
The Customs Solution header is designed to expose access to platform-level signals, enabling
custom development of solutions based on such signals.
• 1.8 Vstby, 3.3 Vstby and 5 Vstby: can be used to power custom solution (such as
daughtercard, etc.) with up to 2 A of current rating capability per each of these voltages. Pins
can also be used to monitor the presence of 1.8 V, 3.3 V and 5 V standby power. Standby
power is always on, even when board power is off.
• HDMI Consumer Electronics Control (CEC): standard communication signal from the HDMI
connector (http://www.hdmi.org/
). There is no HDMI CEC controller onboard; rather, the HDMI
CEC signal is exposed through this header for third party solutions to monitor/control CEC
activity between multiple HDMI devices.
• DMIC_CLK, DMIC_DATA: clock output and data I/O for digital microphone interface; allows
connection of a Digital Microphone.
• SCI/SMI GPIO: input signal for direct connection to a signal (such as a front panel push-
button) capable of triggering an OS-level command in Windows (formerly referred to by
Microsoft as Direct Application Launch*). Voltage level I/O for this pin is 3.3 V. Refer to below
URL for accompanying utility to map triggered event to Windows file.

• PWM[x]: Pulse-width modulation (PWM) signals that can be used to control analog loads, such
as motors or fans. Power rating capability per each PWM signal is 5V at 250mA.
• I2Cx_CLK, I2Cx_DATA: Inter-Integrated Circuit (I
2
C) bus interface signals that allow connection
of low-speed peripherals. Voltage level I/O for these pins is 3.3V. An I
2
C bus specification and
user manual may be found at http://www.nxp.com/documents/user_manual/UM10204.pdf
.
• SMB_CLK, SMB_DATA, SMB_ALERT#: System Management Bus (SMBus) interface signals.
Voltage level I/O for these pins is 3.3 V. General SMBus information can be found on the
platform EDS and at http://smbus.org/specs/
