  Some *I2C* sensors add too much capacitance to the SDA line of the Intel Edison
  Arduino breakout board, thus the signal sticks to a logic 1. When this happens,
  -other sensors connected to the I2C bus are unusable. While there is no generic
  -solution for this limitation, in most cases the sensor works on the Intel
  -Edison Mini-breakout. When this board is not an option, the sensor can be
  -sometimes replaced with the same model from a different vendor.
  +other sensors connected to the I2C bus also become unusable. In order to solve
  +this problem, an I2C repeater that isolates the capacitance on the bus, such as
  +the PCA9517 can be used.
  The Intel Edison *SPI* bus can corrupt data being sent across when certain
  sensors are connected to it, if using an old image. This has been resolved with
