Power Supply
You can power up the development board either from a laptop-style DC power input
or from the PCI Express edge connector. The laptop supply must be a 19-V/6.32-A
rated supply. The DC voltage is then stepped down to various power rails used by the
board components.
outlines the allowable power inputs.
An on-board multi-channel analog-to-digital converter (ADC) measures the current
for several specific board rails.
