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 the 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) measures both the
voltage and current for several specific board rails. The power utilization is displayed
in a GUI that graphs power consumption versus time.
