You can use this setup during the design phase when custom hardware is not yet available.
For the Power Profiler Kit (PPK), this is a typical configuration that allows quick setup and current measurements in reference applications from the SDK or in custom applications.
In this case, the connection to the Power Profiler app is provided by the SEGGER J-Link on the nRF5 DK with a power supply applied on the Development Kit (DK). The configuration for this use case is shown in the following figure.
Figure 1. Measuring current on the nRF5 DK
Make sure that the following are configured:
- The PPK is connected to the nRF5 DK as described in Connecting the Power Profiler Kit to an nRF5 DK.
- The DUT select switch (SW2) is in the DK position.
- The Power select switch (SW4) is in the DK position.
- The COM switch (SW3) is in the DK position.
- The USB cable is plugged into the USB connector on the nRF5 DK and connected to a computer with the Power Profiler app.
