Power Profiler Kit v1.1.0

Measurement system

The Power Profiler Kit (PPK) is driven by the nRF52832 System on Chip (SoC), which uses its analog-to-digital converter (ADC) to measure a voltage drop over a series of measurement resistors. Resistor values are used to calculate the power consumption. The PPK has three different measurement ranges, which are managed by an automatic switch circuitry.

To send the data to the desktop application, the nRF52832 SoC on the PPK uses the SEGGER RTT (Real-Time Transfer). By connecting the PPK to an nRF5 DK, the SEGGER J-Link debug probe available on the nRF5 DK can be used for the computer connection. Alternatively, an external SEGGER J-Link debugger can be used.
