The IMU cannot work without Pypilot or at least the Pypilot boatimu script to determine roll, pitch and magnetic heading. You must also have set the RPI for the I2C port to be functional.
The integrated circuit ICM20948 operates at 1.7V while the RPI operates at 3.3V. There are ICM20948 modules with the ICM20948 that only work at 1.7V while others work between 2 and 6V thanks to a converter and interfaces in the module. Only those operating between 2 and 6V are RPI and Arduino compatible.
Thanks for the hint, yes, I am counting with I2C Interface and Pypilot within OP3. The question was referring to the specific reference/model or IMU sensor that will work best and that is feasible to find. I found some docs in Github about IMU sensors compatible with the available libraries, from the list I was able to find in a reasonable price this model which I have ordered - Pololu MinIMU-9 v5 - hope it works well, I will return the previous mpu version that was not recognized by Pypilot….
