Power
Description
The Xtreme/SBC PCI-104 is designed to be powered from an ATX type power supply, and support many
of the ACPI features like suspend to RAM. A CR1225 battery holder (P16) provides the VBAT for the
Qseven module.
The Xtreme/SBC PCI-104 generates 3.3V on board, to facilitate alternate powering options.
WARNING: If using a PCI-104 power supply that supplies voltages to the Xtreme/SBC PCI-104 through
the PCI-104 connector, you must ensure this power supply DOES NOT supply +3.3V (as this would
conflict with the onboard +3.3V).
Other powering options include
A) +5V & +12V only: The ATX features can be bypassed by powering +5V_SB with same 5 volt supply
as the +5V input pins.
B) +5V only: similar to the above cause, but excluding the +12V which is used only by the backlight and
PCI-104 connector. Before attempting this, verify that this configuration is appropriate for the target
installation.
Using a PCI-104 Power Supply (Providing Power Through the PCI-104 Bus Connector)
When using a PCI-104 Power Supply that provides power over the PCI-104 bus connector ensure the
following:
- The PCI-104 Power Supply should ONLY provide +5V and/or +12V power rails. NOT +3.3V as
mentioned above.
- Install a standard 0.1” pitch jumper on pins 5&6 of the QCG002’s ATX power supply connector
as shown below. This will connect the +5V rail to the +5V-SB rail.
This jumper needs to be done for the following reasons:
o Some Qseven modules require +5V-SB in order to boot properly
o The QCG002 SuperIO chipset requires +5V-SB to operate properly
