To measure the power consumption of the overall board not including the AT32UC3C0512C, remove the 0Ω 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 0Ω 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 0Ω 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 0Ω R24 resistor and insert the amp meter in the 2-pins header J3 (not mounted by default).
