Power Consumption
In order to ensure safe operation of the board, the input power supply must monitor the supply voltage and shut
down if the supply is out of range – refer to the actual power supply specification. Please note, in order to keep the
power consumption to a minimal level, boards do not implement a guaranteed minimum load. In some cases, this can
lead to compatibility problems with ATX power supplies that require a minimum load to stay in regulation. The
mITX-BDW-U
board must be powered through either the ATX+12V-4p (4-pole) connector using standard ATX power
supply or by an external 19V power adapter through the I/O power jack.
ATX12V supply: ATX+12V-4p connector must be used in according to the ATX12V PSU standard.
Hot Plugging power supply is not supported. Hot plugging might damage the board.
The requirements to the supply voltages are as follows:
