Training board + Arduino MKR boards + SSL fails

I’m posting this in case it helps someone. The MPL115A2 barometric pressure has a fixed I2C address of 0x60, The MPL115A2 is incorporated into the IoT Training Controller Light Sound Sensor Action board, so it also uses I2C address 0x60. The MKR line of boards from Arduino (like the MKR1000 or MKR1010) use the Atmel / Microchip ATECC608A cryptgraphic chips. Those chips also use a fixed I2C address 0x60.

So, you can have any two of
the Training board,
an Arduino MKR board or
SSL encryption.

You can’t have all three.
