/**
* A useable Arduino IDE extension (board manager) can be found at
* https://github.com/Lauszus/Sanguino
*
* This extension has been tested on Arduino 1.6.12 & 1.8.0
*
* Here's the JSON path:
* https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
*
* 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.
