STLINK-V3SET vs ST-LINK/V2

[carloV]

Hi,

I'm developing a new project using the STM32H723; I have to decide between the STLINK-V3SET and the ST-LINK/V2, may you help me to understand the main differences ?

If I choose the V3SET, do I need to add any additional module ?

Thank you, best regards.

stlink V3 allows you to install programs faster. 480 Mbit speed support instead of 12 Mbit via USB also allows more data flow while debugging and installing programs.

Thank you Muhammed,

do I need to add any additional module (for debugging and programming) to the V3 ?

The adapter card for compatibility with STLINK-V2 is included in the set.
I have an additional ISOL module to the STLINK-V3 set. STLINK-V3 does not work with cheap USB isolators. If you need isolation, you may consider purchasing this module.

Thank you,

I've bought the V3, I'm using the STM32H723 (I'm not still decided if 144 or 100 pins) to develop a new project; is there a schematic that shows the jtag connector (and connections) needed for a project board ?

Have a look at the schematics of a ST evaluation board (Nucleo, disco or eval) how things are done. I also strongly suggest you start with some of these boards first, learning how tp programm, flash and debug on something that is "known good" . Only then start your own board, so you know what infrastructure you need on the board and how to use is.

I would strongly recommend that you spend some time browsing the Documentation tab on the Product Page for the particular chip you use - there will be lots of application notes and other info there.

And, as @Uwe Bonnes said, spend some time with an ST board to gain familiarity with the part and the tools.
