Connect Tech Xtreme/SBC PCIe/104 Single Board Computer and PCIe/104 Qseven Carrier Board - User Manual
Revision 0.02 20
Power
Description
The Xtreme/SBC 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 generates 3.3V on board, to facilitate alternate powering options.
WARNING: Do not attach a PCIe-104 power supply to P2 (the PCIe104 connector). These power
supplies typically generate 3.3V, which 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
PCIe-104 connector. Before attempting this, verify that this configuration is appropriate for the target
installation.
