Power Connector
In some applications, the PC/104-520 is intended for use as a stand-alone module without a backplane. You
need to have a power connector available on the board for direct power supply. The PC/104-520 is a +5V
only board. Peripherals can obtain additional voltage from the power connector next to the PC/104 bus. The
additional voltages (+12V, -5V and -12V) are not generated onboard the PC/104-520.
