I have purchased the Respeaker 4 mic array for my raspberry pi 4 and I intend to use this to build my own AI smart mirror. I have a problem, however, and was wondering if anyone could help me out? I need my raspberry pi 4 to be cooled by a fan and so I bought a hat with two fans while also having an extension of full access to all GPIO pins. My problem is that the mic only works when directly connected to the raspberry pi and it crashes the pi when I put the mic on top of the fan hat. Any ideas as to why this is a problem?
