36  * A useable Arduino IDE extension (board manager) can be found at
37  * https://github.com/Lauszus/Sanguino
38  *
39  * This extension has been tested on Arduino 1.6.12 & 1.8.0
40  *
41  * Here's the JSON path:
42  * https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
43  *
44  * When installing select 1.0.2
45  *
46  * Installation instructions can be found at https://learn.sparkfun.com/pages/CustomBoardsArduino
47  * Just use the above JSON URL instead of Sparkfun's JSON.
48  *
49  * Once installed select the Sanguino board and then select the CPU.
