Board description:

• Name: Generic STM32H743VIT6
• Link to all relevant information:
  • documentation: https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M
  • Schematics: https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M/blob/master/docs/STM32H7XX_M_schematics.pdf
  • This device is selled on Aliexpress, board marked as DevEBox STM32H7XX_M Ver:V2.0 SN:1907

PS: I have tried to use NUCLEO_H743ZI variant with clock initialization generated in CubeMX, got only I2C and GPIO working, SDMMC and USART hangs for the unknown reason.

note that the variant made for WeAct MiniSTM32H743VITX would likely work for MCUDev DevEBox STM32H743VIT6
#1552
As it uses 25 Mhz HSE crystal same on both boards.
However, do note that the symbols LED_BUILTIN and USER_BTN are different between the 2 boards.
To use the WeAct variannt for MCUDev DevEBox STM32H743VIT6, avoid using the 2 symbols or re-define them in your arduino sketch. you could also simply clone the WeActH743VITX variant file and make mods locally e.g. make a new variant if you prefer.
