My RP4 came with a small case and a fan that uses Pin 1 or Pin 2 and Pin 14…installing the M-Hat 2 takes away those slots. Is there away to utilize the fan instead of tossing it? I heard the Pi4 can produce a lot of heat. I have the latest enclosure for the M-Hat 2.
Thanks,
Bob

Hello Robert,
5V is not accessible on the HAT. If your fan runs with 3.3V you might use pin 2 of J701. See https://www.rooco.eu/2018/08/31/user-guide/ on page 13.
However, your fan might introduce increased electrical noise that will reduce AIS performance and compass accuracy.
