Hello, I just bought a Stlink-v3mods. I was wondering what's the pinout of the cn3 connector. I couldn't find anywhere on the documentation.

 

Thanks.

Hi,

same as on V3 mini : reserved, maybe its the SWD for programming the 723 cpu.

    Hello,

    CN3 is a system connector not associated to any user's function.
