Do you have the developer board PCA10028? If you get it ,you can connect an ampere-meter between the pins of connector P22. This will monitor the current directly.
Or if you want to get the detail of the current change,you can mount a resistor on the footprint for R6. The resistor should not be larger than 10 Ω. Connect an oscilloscope in differential mode or similar with two probes on the pins of the P1 connector and measure the voltage drop. The voltage drop will be proportional with the current consumption.For example, if a 10 Ω resistor is chosen, 10 mV equals 1 mA. Hope it works;
