  /**
   * 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.
