Hi, sorry I am still new to this, but will like to know the difference in the STM32H743ZIT6U Nucleo-144 boards. Will like to know the difference between the MB1137 vs MB 1364 versions?

[BChew.2]

Also, while the MB1137 version allows the embedded STM32 chip to be programmed through the STM32 STLink-Utility software, it appears that the MB1364 version requires an additional hardware device known as the STLink-V3E. Can anyone verify? If not, what software will be required for the programming of the embedded STM32 chip on the MB1364 version? Much help will be appreciated, thank you!

The MB1137 is the NUCLEO-144 board for STM32F and STM32H743ZI (not H743ZI2), while the MB1364 is the NUCLEO-144 board for STM32H723, STM32H743ZI2, STM32H745 and STM32H753, as you can see e.g. in their data brief.

All NUCLEO boards and thus also contain these two an on-board ST-LINK, but on MB1137 the older ST-LINK/V2-1 is still included, while MB1364 has already been equipped with the newer ST-LINK/V3E. More information can be found in UM1974 and UM2407 or the schematics of the boards (see tab CAD resources of its product websites).

Hello @BChew.2​ and welcome to the STM32 Community =)

As said by Peter : MB1137 board is with STLINK V2-1 and MB1364 board is with STLINK V3.

I added the Schematics links:

• MB1137
• MB1364-H743ZI (Rev C-01)

Regarding the software, you will find the link here, and you can use STM32CubeProgrammer for programming STM32 products.
