5 Power and system configuration
5.1 Power supplies
When the mini module is plugged onto the motherboard, power is supplied directly by the motherboard. In this
setup, the external power supply input available on the mini module should NOT be used.
When the SPC58XCADPT176S mini module is used as a stand-alone board, external power supplies must be
used (5.0 V, 3.3 V, 1.25 V).
The following jumpers are used to configure the power supply:
