/**
 * Gen7 v1.1, v1.2, v1.3 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.
