7.2.6 Current measurement
The device has low-power features. It can be interesting to measure the current consumed by the
STM32WBA65RI on the discovery board. To do this measurement easily, there are two possibilities:
1. Measure the supply current of the SoC using an ammeter in place of the jumper (JP2). Refer to
below.
