3.1.5 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).

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).
