As part of an evaluation of the Atmel AT32UC3L064, it can be of interest to measure its power consumption. The two-pin header with a jumper mounted on it is the only connection between the common power plane VCC_P3V3 and the VCC_MCU_P3V3 power plane. By replacing the jumper with an ampere meter, it is possible to determine the current consumption of the AT32UC3L064. To locate the power measurement header, please refer to A functional overview of the Atmel UC3-L0 Xplained kit.
Warning
Do not power the board without having the jumper, or ampere meter, mounted on the power measurement header, otherwise the device may be damaged. The power measurement header is located next to the USB connector as shown in A functional overview of the Atmel UC3-L0 Xplained kit.
