Power Consumption Measurement

To measure the power consumption of the overall board minus the AT32UC3L064, remove the 0Ω R11 resistor and measure the current over the J4 2-pin header (not mounted by default).

To measure the power consumption on the AT32UC3L064 VDDIO, remove the 0Ω R14 resistor and measure the current over the J5 2-pin header (not mounted by default).

To measure the power consumption on the AT32UC3L064 VDDIN, remove the 0Ω R19 resistor and measure the current over the J6 2-pin header (not mounted by default).
