NRF-PPK2

The Power Profiler Kit II (PPK2) from Nordic Semiconductor is an easy-to-use tool for current measurements and power consumption optimization of embedded solutions. It can be connected to any Nordic DK or custom board as a standalone unit, requiring no additional kits or debuggers. The PPK2 supports both source mode and ampere meter mode. In source mode, it supplies power and measures current of the device under test (DUT) with an on-board regulator capable of up to 1A peak currents. Both modes support VCC levels between 0.8V and 5V. In ampere meter mode, the DUT is powered by a separate power source. The PPK2 features an advanced analog measurement unit with a high dynamic input range, allowing accurate current consumption measurements from 200nA to 1A with resolution varying between 100nA and 1mA. It has a sampling rate of 100 ksps, ten times greater than the previous generation. The kit includes 8 digital inputs for low-end logic analyzer support. It is supported through nRF Connect for Desktop's Power Profiler app, which allows measurement data export for post-processing. The kit contents include the PPK2 board, a 4-pin current measurement cable, and a 10-pin logic port cable. Applications include power debugging of embedded applications and estimating battery lifetime of completed solutions.
