NUCLEO-F429ZI Replacement

[mckim0306]

Hi, I am developing the board using the NUCLEO-F429ZI board CN7, CN8, CN9 and CN10 of ST, and I am looking for a product to upgrade to several surfaces such as FD CAN Port.

According to ST's data, Nucleo-H743zi seems to be compatible except NC in CN9, but according to circuit diagram data, it doesn't seem to be compatible at all.

What data should I look at and judge?

I'm sharing the data I saw.
Looking at the circuit diagram and pin map, it seems to be inconsistent.

Hello,

They are not the same board:

NUCLEO-F429ZI: MB1137

Nucleo-H743ZI: MB1364

ST tries to make a pinout compatibly as much as possible between the boards but in some cases couldn't reach 100% of it.

Now, as you are using FDCAN. PD0/PD1 are at the same place on both boards. Meanwhile the ZIO connectors seem to be compatible.

Hello @mckim0306 ,

I recommend you check and compare different part numbers and their characteristics using "Cross selector" feature within STM32CubeMX:
