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 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
board components and installed into the HSMC connectors.
outlines the allowable power inputs.
An on-board multi-channel analog-to-digital converter (ADC) measures the current
for several specific board rails.
