 Product Description


Current measurement tool for embedded development

Power Profiling made easy

The Power Profiler Kit II (PPK2) is an easy-to-use tool for current measurements and power consumption optimization of embedded solutions. The PPK2 connectors can be connected to any Nordic DK or custom board as a standalone unit, i.e. there are no requirements for additional kits or debuggers. The PPK2 supports both a source mode and an ampere meter mode.

In the source mode, shown as source measure unit (SMU) on the PCB, the PPK2 both supplies power and measures the current of the external device under test (DUT). The source mode has an on-board regulator capable of supplying up to 1A peak currents. Both modes support VCC levels between 0.8V and 5V. In the ampere meter mode, the DUT is powered by a separate power source.


High accuracy and resolution

The PPK2 has an advanced analog measurement unit with a high dynamic input range. This allows for accurate current consumption measurements for the entire range typically seen in embedded applications, all the way from 200nA to 1A. This allows measuring everything from Power Off mode of the DUT to the maximum power consumption of any Nordic DUT or external HW with headroom to spare for additional circuit draw, e.g. an nRF9160 DK with external sensors.

The resolution varies between 100nA and 1mA, depending on the current measurement range. The time resolution is also high enough to detect spikes. This is achieved by having a 100 ksps sampling rate of the current, 10x the resolution of the long term view of our previous generation PPK.


Improve code debugging

The PPK2 includes support for 8 digital inputs that can be used as a low-end logic analyzer. This makes it possible to instrument the code and make it easy to link the power consumption to blocks of code being executed.

  1. Great micro amp current measurement tool

    Posted by Unknown on 26th Jan 2021

    Works great out of the box, software is good, but need a bit of improvement with the GUI. Customer support from Glyn is great too.
