/**

 * Sanguinololu board pin assignments

 */

/**

 * Rev B    26 DEC 2016

 *

 * 1) added pointer to a current Arduino IDE extension

 * 2) added support for M3, M4 & M5 spindle control commands

 * 3) added case light pin definition

 *

 */

/**

 * 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.
