Current measurements

nRF7002 Expansion Board II Hardware

The current drawn by the nRF7002 companion IC can be monitored using the nRF7002 EBII.

Current can be measured using any of the following test instruments.

  • Power analyzer
  • Oscilloscope
  • Ampere meter
  • Power Profiler Kit II

For measurement instructions, see the following chapters. Power analyzer measurements are not described in this document.

The nRF7002 companion IC has two available power supplies, IOVDD (1.62 V to 3.6 V) and VBAT (2.9 V to 4.5 V). The nRF7002 EBII is prepared for measuring current on both domains. Only the VBAT domain current measurement is described here, but the approach is the same with the IOVDD supply. See the following table for the corresponding components.
