BOARD STM32 NUCLEO-F334R8

[macam1]

i am using nucleo-f334r8 and when i connect to the laptop the MCU is hot but the voltage on the VDD does not exceed 3.36V. I want to use another MCU therefore I want to use the DEBUGGER (top part) also what should I unplug (jamper) or should I connect?

Hello @macam1 

I think this post should be helpful for you. On your case, CN2 connecter should be off.

Best Regards.

yes, I have done that, but the MCU is still hot, I want to use another MCU outside of the built-in MCU but I need to disconnect the connection between the debugger and the built-in MCU. I have removed the jumper on the ST_link. I wonder if there are still other jumpers that need to be removed?

Everything you need to do is mentionned on the part 6.2.4 of the UM1724.
