    Hello @yogui_ricardo ,

    CN2 is dedicated to connect to the MCU (STM32F723) that manages STLINK-V3 and update its firmware over SWD:

    PA13: SWDIO

    PA14: SWCLK

    But I don't think user needs this connection as the firmware could be updated over ST-LINK micro USB connector (CN1) using STM32CubeProgrammer or ST-LINK firmware upgrade tool.

    Hello @yogui_ricardo and welcome to the Community,

    Which detail are you looking for ?

    Maybe the Gerber files can help you. For that, you can look at the Board Manufacturing specifications in the CAD resources.

    NUCLEO-H753ZI - STM32 Nucleo-144 development board with STM32H753ZI MCU, supports Arduino, ST Zio and morpho connectivity - STMicroelectronics
