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 into the nRF51 DK and nRF52 DK for easy measurements on these boards. 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.
This enables easy power debugging of application code and ensuring maximum power efficient solutions, all at a significantly lower cost than with lab grade tools.
