    Hi ,

    is ther any issue putting on the same bus the following three sensors:

    BME680, BMA640 and I2C ambient light sensor ? 

    They all work at 3.3V volts.

    Hope you can help.

    Thanks.

    We don't have BMA640. 

    But in general it is OK to put both BME680, BMA and light sensor on same I2C bus since both have different I2C address.

    Just need to select the proper pull up register for the I2C bus.
