4.1.4 Power Consumption Measurement
To measure the power consumption of the overall board not including the
AT32UC3C0512C, remove the 0 Ohm R24, 25, 26, 27 resistors and insert the amp
meter in the 2-pins header J6 (not mounted by default).
To measure the power consumption on the AT32UC3C0512C VDDIO, remove the 0
Ohm R26 resistor and insert the amp meter in the 2-pins header J5 (not mounted by
default).
To measure the power consumption on the AT32UC3C0512C VDDIN, remove the 0
Ohm R25 resistor and insert the amp meter in the 2-pins header J4 (not mounted by
default).
To measure the power consumption on the AT32UC3C0512C VDDANA, remove the
0 Ohm R24 resistor and insert the amp meter in the 2-pins header J3 (not mounted
by default).
