It should have them since ages...
Do I mix something up? Does something else play with the pinmuxes?
My AS3935 does mess up the i2c bus with the other sensors on it when
vaux1 is not enabled. So I am trying to move it to the free one.
But i2cdetect -r -y 3 does not work properly.
Anything else missing?
