Power Profiler Kit content and key
features
The Power Profiler Kit (PPK) is an affordable and flexible tool to obtain real-time power consumption
measurements on your designs.
The PPK measures current consumption for a connected nRF5x Development Kit or any external board. It
can measure current from 1 uA up to 70 mA and give a detailed picture of the current profile for the user
application.
The PPK can be used in conjunction with the nRF5x DK to measure current on the nRF5x DK or on an external
board. The hardware is delivered with a desktop application developed in the Python programming language
which makes customization possible. Several measurement configurations are offered which are described in
this user guide.
