Power Profiler Kit
Current measurement tool for embedded development
Power Profiling made easy
The Power Profiler Kit is an easy-to-use tool for current measurements and power consumption
optimization of embedded solutions. The Power Profiler Kit plugs directly onto the nRF51 DK and
nRF52 DK through the Arduino Uno Revision 3 standard pin headers and the special power measurement
header on these kits. This allows easy power optimization with a minimum of effort. There’s also an
additional connector for connecting to and measuring current on external boards, enabling you to
measure current consumption on your final hardware. It supports VCC levels between 1.8 V and 3.3 V
and has an onboard regulator that will supply up to 70 mA to external applications.

Power Profiler Kit Product Brief v1.0
High accuracy and resolution analog measurement
The Power Profiler Kit has an advanced analog measurement
unit with a high dynamic input range. This allows accurate
current consumption measurements for the entire range
typically seen in embedded applications based on nRF devices,
all the way from single µA to tens of mA. For the lowest input
range the resolution is 0.2 µA. The time resolution is also
high enough to detect spikes.This is achieved by having a
77 kHz sampling rate of the current.
Easy to use desktop application
The desktop application supporting the Power Profiler Kit
provides several ways of assessing the power consumption,
both instantaneous and averaged over a set time period. The
kit can be configured to take readings over a period of up to
20 seconds, while simultaneously zooming in on a millisecond
interval of interest. It is possible to measure instantaneous
current for two separate points and at the same time measure
the average current between the points. The points can be set
separately for both windows at the same time. Measured data
can also be exported for post processing.
Improve debugging of code
The Power Profiler Kit supports both external trigger input
and a trigger output. This makes it possible to combine the
use of the Power Profiler Kit with oscilloscopes and logic
analyzers. Code-synchronized measurements can be achieved
by connecting the external trigger input to an I/O pin on the
device being tested. This I/O pin must be configured to output
a synchronization pulse.
Being able to synchronize current measurement with
code makes it easier to spot software problems quickly.
