/**
 *  Rev B  2 JUN 2017
 *
 *  Converted to Arduino pin numbering
 */

/**
 *  There are two Arduino IDE extensions that are compatible with this board
 *  and with the mainstream Marlin software.
 *
 *  Teensyduino -  https://www.pjrc.com/teensy/teensyduino.html
 *  Installation - https://www.pjrc.com/teensy/td_download.html
 *
 *    Select Teensy++ 2.0 in Arduino IDE from the 'Tools > Board' menu
 *
 *    Note: With Teensyduino extension, the Arduino IDE will report 130048 bytes of program storage space available,
 *    but there is actually only 122880 bytes due to the larger DFU bootloader shipped by default on all Printrboard RevF.
 *
 *  Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support
 *
 *    Installation:
 *
 *       1. Go to the above URL, click on the "Clone or Download" button and then
 *          click on "Download ZIP" button.
 *       2. Unzip the file, find the "printrboard" directory and then copy it to the
 *          hardware directory in Arduino.  The Arduino hardware directory will probably
 *          be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
 *       3. Restart Arduino.
 *       4. Select "Printrboard" from the 'Tools > Board' menu.
 *
 *  Teensyduino is the most popular and easiest option.
 */

/**
 *  To burn the bootloader that comes with Printrboard HID extension:
 *
 *   1. Connect your programmer to the board.
 *   2. In the Arduino IDE select "Printrboard" and then select the programmer.
 *   3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
 *   4. The programmer is no longer needed. Remove it.

 * reassigned it to a second fan for the extruder heater.  It's

 * See https://printrbot.zendesk.com/hc/en-us/articles/115003072346
 *
 * If you have REV F6 you probably also want to set E0_AUTO_FAN_PIN
 * to PRINTRBOARD_F6_HEATER_FAN_PIN (44).
 *
 * Define NO_EXTRUDRBOARD if you don't have an EXTRUDRBOARD and wish to
 * reassign different functions to EXP1.
 *
 * Define NO_EXTRUDRBOARD_OUTPUT_SWAP if you have a REV F5 or lower and
 * want to use EXTRUDRBOARD A for E1 and EXTRUDRBOARD B for E2.
