Nordic SemiconductorPower Profiler Kit II (PPK2) is an affordable, flexible tool that provides hardware and software engineers with a simple method for measuring the average and dynamic power consumption in embedded solutions. The PPK2 can be connected to any Nordic Development Kit (DK) or custom board as a standalone unit, with no additional kits or debuggers.

An Ampere Meter mode, as well as a Source Mode (shown as AMP and Source Measure Unit (SMU) respectively on the PCB) are supported. For the Ampere Meter mode, an external power supply must source VCClevels between 0.8V and 5.0V to the Device Under Test (DUT). For the source mode, the PPK2 supplies VCClevels between 0.8V and 5.0V, and the on-board regulator supplies up to 1A of current to external applications.It is possible to measure low sleep currents, the higher active currents, as well as short current peaks on all Nordic DKs, in addition to external hardware.

Power for the PPK2 comes from a standard 5.0V USB port. The DUT can either be powered by an external source or from the PPK2's source. The PPK2 eliminates the need for a bench power supply since it can provide an output adjustable voltage from 0.8V to 5.0V and a dynamic output current from 1μA to 1A.

The PPK2 also offers engineers eight digital inputsthat can be used as a low-endlogic analyzer. This makes it possible to instrument the code and make it easyto link the power consumption to blocks of code being executed.

SOFTWARE

The Nordic SemiconductorPower Profiler Kit II is supported by the Power Profiler App running in thenRF Connect for Desktopframework foranalyzing both average and instantaneous current consumption. Using the PPK2, the Power Profiler App can show both average acquisition times and high-resolution events in the same window. Measured data can be exported for post processing.
