What is the difference between Nucleo-H743ZI and Nucleo-H743ZI2?

[Peter.Farkas [hun]]

If the Nucleo-H743ZI2 is newer, why Nucleo-H743ZI is the active version? I have a Nucleo-H743ZI2 board. So, where can I find schematic and support page for Nucleo-H743ZI2?

The ZI2 has the ST-LINK/V3 and the V-step STM32H743 capable of 480 MHz operation.

Handful of pins, including LEDs have changed. The .H files for the BSP look for a command line define.
