PPK 2 and Unihiker: Automate Your Power Profiling Projects

The Power Profiling Kit 2 (PPK 2) from Nordic Semiconductor is a versatile tool for accurately measuring the power consumption of your projects. Combining this with the Unihiker, a compact Linux-based single board computer with a touchscreen, creates an efficient setup for power profiling.

Watch Ian discuss Power Profiling with the Ppk 2, Python & Unihiker in this episode of The Electromaker Show

Overview of Power Profiling Kit 2

The PPK 2 is designed to provide detailed power consumption metrics. It offers multiple power supply options and automation capabilities, making it an essential tool for developers looking to optimize their projects' power efficiency. The kit is particularly useful for profiling current usage across different components and conditions.

Integrating PPK 2 with Unihiker

Using Unihiker you can automate the power profiling process with ease. The Unihiker's unique form factor and touchscreen interface, coupled with its Linux operating system, provide a user-friendly platform for running the PPK 2. By leveraging the unofficial Python API, users can set up automated measurements and display real-time data directly on the Unihiker's screen.

Practical Applications and Examples

A practical example is profiling a temperature and humidity sensor using the PPK 2 and Unihiker. This setup involves connecting the sensor to the PPK 2, which then interfaces with the Unihiker via USB. The Python API is used to control the PPK 2, measure the sensor's current usage, and display the data. This combination allows developers to gain insights into their project's power consumption and make necessary adjustments.

The integration of the Power Profiling Kit 2 with Unihiker offers a powerful and compact solution for detailed power consumption analysis. Whether you are optimizing small sensors or complex systems, this setup provides the tools needed for effective power management.
