Powering a peripheral using STM32WB5MM-DK

This might be a dumb question but can the STM32WB5MM-DK power a 3.3V peripheral device?
This part of the user manual makes it sound like the whole Arduino shield should not be used to supply any sort of power:

Yet according to this table, pin 4 should be able to do what I need

Hello @Hichamm 

"Do not supply 3.3 V or 5 V from the ARDUINO® shield. Supplying 3.3 V or 5 V from the
ARDUINO® shield could damage the STM32WB5MM-DK Discovery kit" means that you should not supply the STM32WB5MM-DK board with the ARDUINO connector. But you can use the 3V3 pin or the 5V to supply your sensors for example.

Best Regards.

Thanks, the wording made it quite misleading but it makes sense now.
