Product Data Sheet

3.9 Power tree
The board can be powered via USB connector, V
IN
or V
USB
pins on headers.
NOTE:
Since V
USB
feeds V
IN
via a Schottky diode and a DC-DC regulator specified minimum input voltage is 4.5V
the minimum supply voltage from USB has to be increased to a voltage in the range between 4.8V to
4.96V depending on the current being drawn.
