Hi Antonio,

according to a specification:

MCU cannot be supplied by +5V.

You can use +5V to supply external devices.

Could you answer to my question I have sent to you on other post?

Thank you Tomasz, my doubt was because I read this phrase:
"Supplying power to the 5V connector supplies the emulator part of the board. The emulator regulates the power to 3.3V and supplies the target via the 3.3V Jumper"
