/**
 * IMPORTANT NOTE:
 * Rambo users should be sure to compile Marlin using either the RAMBo
 * board type if using the Arduino IDE - available via the link below - or
 * the 'rambo' environment if using platformio, by specifying '-e rambo' on
 * the command line or by changing the value of the 'env_default' variable to
 * 'rambo' in the supplied platformio.ini.
 *
 * If you don't compile using the proper board type, the RAMBo's extended
 * pins will likely be unavailable and accessories/addons may not work.
 *
 * Instructions for installing the Arduino RAMBo board type for the
 * Arduino IDE are available at:
 * http://reprap.org/wiki/Rambo_firmware
