Using IoTT Shields with EX 8874 (Video#130)

How to combine IoTT Arduino shields with the new EX-8874 motorshield? The EX-8874 is using a rather unconventional approach to using the VIN power rail, which can cause problems when adding other shields to the stack. In this video I am looking into the Arduino power options and how to best apply them to the typical use cases of a DCC-EX Arduino stack.
