1.5.3 Power Supply
In order to avoid damaging any devices, make sure that they have been installed properly prior to
connecting the power supply.
It is recommended that the board be used with a power supply that supports a minimum
current load of 0.3A or less on the 5V supply rail and 2A or less on the 3.3V supply rail.
This board with CPU and memory may draw as little as 400mA of 5V and 2A of 3.3V during
start-up (increases depend on installed devices). The power supply under consideration must
be verified as compatible with the projected total system start-up loads for these supply rails.
If the power supply minimum current level requirements are not at or below the level of
current loads that are actually drawn, unpredictable start-up operation may result, such as the
power supply latching off. If this occurs, the AC input to the power supply must be removed
and re-attached or the power supply switch cycled off and on, in order to turn the system
back on.
