4.15.6 Power Distribution
There are two power connectors available onboard the SBC-S32V. These 4 pin
shrouded header connectors can be used to connect an external fan or for
additional supply voltages required for miniPCIe modules. The current rating is
limited to 1A per pin. The voltages are switched on and off by the main power
switch. The +12V voltage is sourced by the input voltage, which is derated by
maximal 550mV, caused by the input polarity protection diode. An external load
must no feed in any reverse current or voltage during any power state, f.e. an
external inductive load must be equipped with a freewheeling circuit.
