Geeetech® RAMPS-FD Controller Mainboard For Due Reprap 3D Printer

Feature When you use Due as the controller of your 3D Printer you may find the RAMPS1 4 is not compatible with DUE As you know the Due is a microcontroller board based on the SAM3X8E ARM Cortex M3 the importance is the SAM3X8E chip used on the Due operates at 3 3V worse applying 5V to the Dues inputs will likely damage the chip So we create a new RAMPS variant which is compatible with the Due to replace Ramps1 4 Why should I use Ramps FD instead of Ramps1 4 Campare Ramps FD with Ramps1 4 the improvements of Ramps FD are below The RAMPS FD has other hardware protection through the jumper cap control motor drive IC The RAMPS FD Much more than Ramps1 4 2 way PWM The RAMPS FD has Larger driving power than Ramps1 4 The RAMPS FD power has two choices 12V and 24VWhy should I select DUE instead of Mega CPU operates at 3 3V High current IO pins are capable of 15 mA source 9 mA sink Low current IO pins capable of 3 mA source 6 mA sink CPU package has an absolute max of 130mA The Due has 1 dedicated SPI port and 4 multipurpose USART SPI ports The SPI port is only routed to the 6 pin header used for ICSP on Mega but this is not used for ICSP on Due The Due does not have any EEPROM Due has lower power computing faster and flash sram bigger than mega2560 You will need to buy aLCD adapter for RAMPS FD Package included 1 x RAMPS FD Shield for DUE
