  * **MICSV89** is not compatible with the Intel Galileo due to the inability to
  change the I2C bus speed to 100 KHz.

  * **InvenSense MPU9150 & MPU9250** will be unable to report magnetometer data
  when used on the Intel Edison Arduino board because the integrated compass
  chips are not detected on the I2C bus.
