3. If it is necessary to do power consumption measurement during debugging, STMicroelectronics has an
interesting solution. It is possible to use an STLINK-V3PWR. This product allows two sources of supply: a first
for the current measurement on the STM32WBA65RI, and a second source to supply the rest of the board
(LEDs). As in the previous case, the jumper (JP2) must be OFF, and the main supply (for current
measurement) connected to pin 1 of JP2 (refer to
set JP4 OFF and connect this source to the top side (pin 10, 8, 6, 4, or 2 of JP4).
The supply voltage on JP2 must be 3V3.
The details above concern the supply of the board by STLINK-V3PWR. The debug probe must be connected
on the CN14 on the mezzanine board (MB2143).
