Hi, New user here,
I work specifically with Spark Core Micro-controller shields and development. These devices are new to the market this year. Here is a link to there Community: http://community.spark.io
Would you please ADD Platorm Type in Listing Page for “Spark Core” along with Arduino, Raspberry Pi, etc.
After you do this I can post on the Spark Core Community forum your system now includes Spark Core sells, etc.
