5 Power and system configuration
5.1 Power supplies
The mini module can be powered by providing voltages either supplied externally by the 2-Way PCB screw
connector (CN1) or supplied by the motherboard.
When the mini module is connected to the motherboard (MB), 3V3 and 5V0 are supplied by MB connector
selecting the associated jumpers. In this setup the external power supply input available on the mini module
MUST NOT BE USED.
When the SPC58NHADPT176S Rev. A mini module is used as a stand-alone board, 5V0 voltages must be
supplied externally, 3V3 and 1V2 voltages will be generated internally by specific circuit on the mini module.
The following jumpers are used to configure the power supply (common for all supported devices):
