Description
The whole board can be powered over the USB connector.
The whole board can be powered over the USB connector. The PAN9520
is still powered if the peripherals are deactivated over PER_EN.
The current measurement pin header X13 can be used for powering the
PAN9520 only. Please note that GND must be connected via a different
connector (e.g. X19 as shown below).
For power supply, the pin 3V3 and the pin 5 V of the Arduino socket can
be used.
If the pin 5 V is used, it is recommended to set "5 V Sel." to "input". This
will add a diode into the supply path, which avoids problems when
connecting USB cables.
