Power Supply
The starter board's power is provided through a laptop-style DC power input. The
input voltage must be in the range of 9 V to 16 V. The DC voltage is then stepped
down to various power rails used by the components on the board.
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
using a GUI that can graph power consumption versus time.
Power Distribution System
Figure 2–7 shows the power distribution system on the starter board. The currents
shown are conservative absolute maximum levels and reflects the regulator
inefficiencies and sharing.
