Drive innovations in the field of low-power technologies

Our goal is to provide an easy-to-use, low-cost, open-source solution that includes compatible hardware and software sets of tools. This comprehensive solution is designed to fulfill the need for firmware energy profiling, as well as State of Charge (SoC) and State of Health (SoH) algorithm evaluation for real LiPo battery-powered embedded devices. The system should provide high-speed sampling rates (up to 2MSPS) and high current rates (up to 5A) for precise measurements. Thanks to this system, optimizing power usage, extending battery life, and improving overall system efficiency will be easy.

With our solution, we strive to support advancing energy-efficient technologies and contribute to the sustainable utilization of LiPo batteries. We believe that by providing an accessible and cost-effective solution, we can assist in developing and optimizing battery-powered embedded devices across various industries.

We empower developers and researchers to contribute to and enhance the capabilities of the platform. Collaboration within the community can lead to continuous improvement and the development of innovative features and functionalities.

Energy Profiler Probe

The Energy Profiler Probe (EPP) enables engineers to precisely measure and analyze voltage, current, power, and energy consumption in real time, helping them understand and optimize the behavior of battery-powered and low-power devices. By providing detailed insights into how devices consume energy under different operating conditions, the EPP supports critical tasks such as power profiling, battery characterization, and validation of energy-saving strategies.

Beyond simple measurement, the EPP also acts as an active debugging tool, allowing developers to stimulate systems with programmable load patterns and evaluate their dynamic responses. This combination of measurement and controlled stimulation makes the EPP an indispensable instrument throughout the design, testing, and optimization phases of energy-sensitive applications.

Key features:

  • High-speed voltage and current sampling, up to 1 MSPS
  • Real-time power and energy computation
  • Programmable load generation with custom waveform support
  • Integration with OpenEPT GUI for advanced visualization and analysis
  • Flexible streaming interfaces (Ethernet)
  • Detailed status and error logging for robust debugging
  • Support for battery profiling and dynamic energy analysis
