STM32H743ZIT6 (NUCLEO-H743ZI) not compatible with the expansion board X-NUCLEO-CCA02M2?

HMajc.1 · ‎2022-12-08

I wanna do a live audio processing project and I got an X-NUCLEO-CCA02M2 expansion board with the integrated mics as it says it's compatible with all STM32 boards. However, the pins seem misaligned, i.e. i can't just plug it nicely on top as shown in the manuals or tutorials. Am I missing something? Is there some nonstandard way of connecting those two particular modules together?

Hello @HMaje.1,

To connect an X-NUCLEO-CCA02M2 expansion board to a NUCLEO-F746ZG for example development board, morpho header connectors must be soldered on the relevant footprint available on the STM32 Nucleo.

Also, you do not need to solder the whole 2 x 80 pin header but only a pair of 2 x 38 pin stripline connectors as mentioned in Getting started with the digital MEMS microphone expansion board based on MP34DT06J for STM32 Nucleo - User manual

Oh, I see, that's unfortunate.

Thank you for a quick response, I'll refer to the materials provided.

Best,
