      According to the documentation, I can activate i2c3 and i2c5 with output pins 31, 33, 35, 37. Is it possible to change the output pins to other pins? Thank you.

          @maxpol I2C3 I2C5 cannot be changed to other pinsOf course, you can try opening other I2C channels.

            @george Thx a lot for your prompt response.

            Could you point me to the documents where I can figure out which i2c channels I might be able to open on the gpio pins?
