Note
Power header
The power header can be used to connect external power to the SAM4S Xplained Pro kit. The kit will
automatically detect and switch to the external power if supplied. The power header can also be used as supply
for external peripherals or extension boards. Care must be taken not to exceed the total current limitation of the
on-board regulator for the 3.3V regulated output. To locate the current measurement header, please refer to
Figure 1.1, “SAM4S Xplained Pro evaluation kit overview”

is a power source connected to EDBG USB, the EDBG is activated and it will consume more
power.
