The current drawn by the nRF52832 System on Chip (SoC) can be monitored on the nRF52 DK.
Current can be measured using any of the following test instruments:
See the following chapter for important information on the DK measurement setup. If the PPK2 will be used for measuring current, see the Power Profiler Kit II User Guide for additional instructions. Power analyzer measurements are not described in this document.
It is not recommended to use a USB connector to power the Development Kit (DK) during current measurements due to potential noise from the USB power supply. It is recommended to power the DK from a coin cell battery or external power supply on connector P21 (1.7 V to 3.6 V).
After programming the nRF52832 SoC, the USB must be disconnected and the DK power cycled to reset the debugger chip before current measurement.
For more information on current measurement, see the tutorial Current measurement guide: Introduction.
