Power Supply

The development board's power is provided through a laptop style DC power input.
The input voltage must be in the range of 14 V to 20 V. The DC voltage is then stepped
down to various power rails used by the components on the board and installed into
the HSMC connectors.
An on-board multi-channel analog-to-digital converter (ADC) is used to measure both
the voltage and current for several specific board rails. The power utilization is
displayed using a GUI that can graph power consumption versus time.
