Hi
I have a question regarding the Respeaker 4-Mic Array.
(https://www.seeedstudio.com/ReSpeaker-4-Mic-Array-for-Raspberry-Pi.html)
Looking at the product images on the above site, it seems that there are two types of microphones mounted on the Respeaker 4-Mic Array.
The gold-colored microphones appear to be SPU0414HR5H-SB(Knowles). However, I am unsure about the model number of the black-colored microphones.
Is the model number of the black microphones MSM321A3729H9BP?
Also, would it be possible to share the source of this information (e.g., material list)?
BR,
