ppk2-api
API for Nordic Semiconductor's Power Profiler Kit II (PPK 2).
Decision gist · record as of 2026-08-14
Yes, if you own a PPK 2 and need automated power measurement. The package is actively maintained, has low install friction, and fills a genuine gap (no official automation support). The GPLv2 license is a consideration for proprietary projects. The 1162-day gap since first release and over a year since the last release suggest the core API is stable but may not be under active feature development.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a PPK 2 device connected to a serial port; the serial port path must be known and accessible to the Python process.
- Low install friction with a single runtime dependency (pyserial).
- Package is actively maintained with recent commits and a modest but engaged user base, though last release was over a year ago.

What it is and what it does
ppk2-api is a Python wrapper around Nordic Semiconductor's Power Profiler Kit II hardware, enabling automated power consumption measurement and logging without the GUI. It communicates with the PPK 2 device over a serial port and provides methods to configure measurement modes, set voltage levels, and stream power samples in real time.
The package offers two usage patterns: a basic synchronous API that reads samples on demand, and a multiprocessing variant that runs a background polling process to buffer up to 10 seconds of data, reducing the frequency of manual polling. It is cross-platform and requires only pyserial as a runtime dependency, making it suitable for embedded test automation, power profiling in CI/CD pipelines, and long-term power monitoring applications.
Use it for
- Automated power consumption testing in embedded device development workflows and CI/CD pipelines
- Long-term power monitoring and data logging for battery-powered device optimization
- Real-time power measurement during firmware development without manual GUI interaction
- Batch power profiling across multiple device configurations or firmware variants
- Integration of power metrics into test reports and performance dashboards
