The Power Profiler Kit (PPK) is an affordable, flexible tool that measures the real-time power consumption of your designs.
The PPK measures power consumption for a connected nRF5 DK or any external board. It measures current from 1 μA to 70 mA and gives a detailed picture of the current profile for the user application.
The PPK can be used in conjunction with the nRF5 DK to measure current on the nRF5 DK or on an external board. The hardware is delivered with an application that is installed using nRF Connect for Desktop. There are several measurement configurations, which are described in this user guide.
Key features
- Variable power supply voltage ranging from 1.8 V to 3.6 V (software configurable)
- Maximum 70 mA current measurement
- Resolution down to 0.2 µA
- Automatic switching between three current measurement ranges ensuring optimal resolution
- Measurement accuracy better than ±20 % (average currents measurement)
- Desktop application for measurement analysis
- Real-time current measurement display
- Recording display up to two minutes
- Real-time display with a resolution down to 13 µs
- Internal/external trigger
Applications
- Quick power consumption measurements on a firmware running on an nRF5 DK or an external board
- Accumulative measurements, such as average, peak, maximum
- Instantaneous measurements presented as waveform plots
