+ *
+ * This extension has been tested on Arduino 1.6.12 & 1.8.0
+ *
+ * Here's the JSON path:

+ *
+ * When installing select 1.0.2
+ *
+ * Installation instructions can be found at https://learn.sparkfun.com/pages/CustomBoardsArduino
+ * Just use the above JSON URL instead of Sparkfun's JSON.
+ *
+ * Once installed select the Sanguino board and then select the CPU.
