Current Measurement
The power to the target controller ATtiny416 is connected from the
VREG
supply to the targets
VCC
supply with a 0Ω
resistor, as shown in the figure below. To measure the power consumption of the device, remove the 0Ω resistor and
replace it with an ammeter. The ammeter can be connected between the
VREG
and
VCC
pads for easy
measurement.
