Pi4 ReSpeaker 2-Mic HAT + Fan Shim

#1

Hello : I need help with 2-Mic HAT from ReSpeaker and Pimoroni Fan Shim to both work on to my Pi4 board

I don’t need any extra features of the fan shimm such as button, LED, etc. I just need it turn On at 65 and turn off at 50.

I don’t use buttons, LED, I2C or JST on the Mic Hat. I use only the 3.5mm audio out and the microphones.

Pin out for the 2-Mic HAT is here: https://pinout.xyz/pinout/respeaker_2_mics_phat
Pin for fan SHIMM here: https://pinout.xyz/pinout/fan_shim

Is there a way to get this working?

There’s pin conflict on two boards, I’m afraid you have to re-map the Fan Shim pin and solder it on the pins which haven’t been used on Pi HAT, and mount the Fan Shim board on the corner of Pi via a screw. what do you think?

That’s a hack and might work but won’t be stable. We will ship 100s of these devices to field, so can’t risk it. but thanks for the suggestions.
