5.12. Power Supply

Power for this board will be provided through an external Laptop style DC power brick connected to a 4-pin power DIN jack (CUI Inc. PD-40S). The input voltage must be in the range of 12V +/- 5%. This DC voltage is then stepped down to the various power rails used by the components on the board.

Some power rails on the board will have the option to be supplied from an external source via banana jack connectors by first removing a jumper for that power rail.
