NUCLEO-F446RE with steval-mic003v1: direct connection

[Matthew_]

Hello guys, I would like to know if it is possible to directly connect  NUCLEO-F446RE board with  steval-mic003v1 mic array without any expansion board. Would love to know your feedback and much appreciated.

Check schematics of the two boards.

Look at the datasheets of the STM32F446RE and IMP34DT05; check if signal levels are compatible.

 

The STEVAL-MIC003V1 Product Page says it's intended for use with X-NUCLEO-CCA02M1 - so also check-out the documentation (including schematics) for that to see what it's providing...

 

There's also X-NUCLEO-IKS02A1 ...

Thanks, I managed to make it work.

The single answer to my question for other people who might be wondering the same thing in the future is "Yes". You can play around with different peripherals.

Hi @Matthew_ ,

Would really appreciate if you could share how you directly connected steval-mic003v1 to NUCLEO-F446RE board. Thanks.

Hello @mar05Thd , it is for a project during my internship and I may not completely remember this. But, I remember testing with I2S, SAI peripherals to interface with steval-mic003v1. You can connect to the individual pins of each microphone and try to interface.
