Need to explain to us what do you need behind your original question: "diffrence between stm32f29i-disc1 and stm32f429zi"

@syedhashmiraza is misunderstanding / misusing the term, "microcontroller"; eg,

@syedhashmiraza The stm32f429i-disc1 is not a microcontroller - it is a board which contains, among other things, a microcontroller.

The microcontroller is the stm32f429zi 

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    The difference between a chip and a board:

    In this case, this is the STM32F429I-DISC1 board:

    And this is the stm32f429zi chip (a microcontroller) - mounted on the rear of the board:

    first, there is no board called stm32f29i-disc1 I supposed you are talking about stm32f429i-disc1. So please provide the correct board name.

    second, as I said they are different disc1 termination means it’s a board : https://www.st.com/en/evaluation-tools/32f429idiscovery.html

    while stm32f429zi is a microcontroller:
