Power supplies
When the mini module is plugged onto the motherboard, the 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 SPC570SADPT100S mini module is used as a stand-alone board , the external power supplies must
be used (5 V, 3.3 V, 1.25 V).
The following jumpers are used to configure the power supply:
