5.2.2. Power Supply

Figure 12: Sharky power supply connections

VDD, VDDUSB and VBAT must be connected to power supply. Optionally VDDA can be
connected to power supply or to an external AVDD level.

5.2.3. Reset Circuit

Reset pin is already pulled up internally in the STM32WB. From ST datasheet:

So NRST pin can be directly connected to the NRST signal of JLink V3SET
