63  * A useable Arduino IDE extension (board manager) can be found at
64  * https://github.com/Lauszus/Sanguino
65  *
66  * This extension has been tested on Arduino 1.6.12 & 1.8.0
67  *
68  * Here's the JSON path:
69  * https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
70  *
71  * When installing select 1.0.2
72  *
73  * Installation instructions can be found at https://learn.sparkfun.com/pages/CustomBoardsArduino
74  * Just use the above JSON URL instead of Sparkfun's JSON.
75  *
76  * Once installed select the Sanguino board and then select the CPU.
