5.2. Power Supply
Power supply for this development kit is provided through an external laptop style DC power brick connected to a 6-pin ATX power connector. The input voltage is in the range of 12V +/- 5%. This DC voltage is then stepped down to the various power rails used by the components on the development board.
Important: The power rails on the development board have the option to be supplied from an external source through a banana jack or power terminal connectors by first disabling corresponding power regulator using SW9/S14 DIP Switch.
