Pypilot Compass Linearity

[rotorman]

please post a picture of your setup.    Some of these boards require voltage conversion since the icm20948 uses 1.8 volts.

Hi Sean, how are you? Do you remember me? Geza. We have meet in Opua in NZ before when you had the affair with customs. You have done an amazing job with pypilot. Since I had a lightning strike and all electronics are gone now I am attempting to build a pypilot.

UPDATE ------------
It is working. It just takes a long time until the web interface is available.

Original problem:
The board containing the icm20948 has a voltage regulator and can take anything from 3-5 volts so I think that is fine.
I have just checked the log and it seems like icm20948 is detected and initialized. However I am unable to open the web interface. If I disconnect the icm209048 then the web interface works.
Here is the log with ICM-20948 connected:

I have attached some photos of the temporary connection.

Hey thank you very much for having a look.
