The Power Profiler Kit (PPK) contains connectors and measurement components.
Measurement system
The Power Profiler Kit (PPK) is driven by the nRF52832SoC, 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.
Connectors
Access to the Power Profiler Kit (PPK) is available from a set of connectors.
Switches
Use the switches on the Power Profiler Kit (PPK) to select either the DUT on which current is measured, the power supply, or the SEGGER J-Link connection.
