Module Description
3.7
On-Board Power Supply
The CMx-BTx devices can be run with only 5 volts. If a StandBy mode is needed, the 5V
StandBy voltage has to be connected in addition to the 5V supply.
The +12V supply is only needed for driving an LCD backlight.
All other voltages needed to run the module are generated on the module itself.
Alternatively, the module can be powered by a stacked power supply, connected through either
the PC/104 connector or the PCI-104 connector. In such a case, the module checks if the
PCI_3P3 voltage is applied from this source and can then bypass the PCI-3P3 voltage. So the
PCI_3P3 voltage can be self contained and will not be provided by the module.
The power connector is a JST-B15B-EH, 1.5 mm pitch single row connector. The cable kit pro-
vides an adapter cable from this to a standard 20-pin ATX connector.
