35 / 5000 Is there anyone who connected BTT MMU2 dip and used it? Help me

I want to use BTT MMU2 dip for klipper.
MMU2 dip is using STM32F030 MCU. However, Raspberry Pie does not have that MCU list in make menu config, so I created a klipper.bin file with a similar STM32F031 and flashed it. Is this okay?
And which one should I connect with Raspberry Pie and MMU2 dip board? I’ve connected to Micro 5pin, do I need to connect it to Uart? Or do I need to connect after enabling SPI on the board SPI and Raspberry Pi GPIO? I’m curious about this.

I hope you understand even if the sentence is weird because it is translated through a translator

As far as I can tell, it is not supported. See [WIP] BTT MMU DIP board integration and HC595 by kakou-fr · Pull Request #3606 · Klipper3d/klipper · GitHub, which was never finished.
