Power is normally supplied to the cpuModule through the PCI bus connectors (CN16). If you are placing the
cpuModule onto a PC/104-Plus or PCI-104 stack that has a power supply, you do not need to make additional
connections to supply power.
If you are using the cpuModule without a PCI-104 or PC/104-Plus stack or with a stack that does not include a
power supply, refer to Auxiliary Power (CN3) on page 26 for more details.
Some PCI-104 and PC/104-Plus expansion cards may require +3.3V supplied on the PC/104-Plus (PCI) connector
(CN16). To learn how to supply this voltage, refer to Auxiliary Power (CN3) on page 26 and Jumper Settings and
Locations on page 86.
