Kit Modifications - Microchip Technology SAM R30 Xplained Pro User Manual

1. No current measurement or an external MCU current measurement: The XAM is bypassed,
thus the MCU and peripherals are supplied directly by the regulator. Set both jumpers (MCU and
I/O) in the "BY-PS(BYPASS)" position. In this configuration, it is also possible to connect an
external measurement tool with the Xplained Pro MCU power measurement header to measure
MCU current directly instead of using the XAM.
2. MCU current measurement: The XAM measures only the MCU current while the peripherals are
supplied directly by the regulator. For this configuration, place the jumper for "I/O" (peripherals) into
the "BY-PS(BYPASS)" position and the "MCU" into the "MEAS (MEASURE)" position.
3. Peripherals measurement: The XAM measures only the peripherals current while the MCU is
directly supplied by the regulator. For this configuration, place the jumper for "MCU" into the "BY-
PS(BYPASS)" position and the "I/O" jumper into the "MEAS (MEASURE)" position.
4. MCU and peripherals measurement: In this configuration, both the MCU and peripherals are
measured by the XAM. Place both jumpers on the "I/O" and "MCU" headers in the "MEAS
(MEASURE)" position.

Kit Modifications

The SAM R30 Xplained Pro contains several resistors that can be used to disconnect I/O pins of the
ATSAMR30G18A SoC from connectors and on-board ICs, and to disconnect power signals.
