Reprap Ramps-FD Control Board Ramps1.4 Improved Version For 3D PrinterIntroduction:When you use Arduino Due as the controller of your 3D Printer, you may find the RAMPS1.4 is not compatible with DUE. As you know the Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3, the importance is the Atmel SAM3X8E chip used on the Due operates at 3.3V,worse applying 5V to the Due's inputs will likely damage the chip.So we create a new RAMPS variant which is compatible with the Due to replace Ramps1.4.Why choose Ramps-FD instead of Ramps1.4?The RAMPS-FD has other hardware protection, through the jumper cap control motor drive ICThe RAMPS-FD much more than Ramps1.4 2-way PWMThe RAMPS-FD has larger driving power than Ramps1.4The RAMPS-FD power has two choices: 12V and 24VWhy choose Arduino DUE instead of Arduino MEGA?CPU operates at 3.3VHigh-current IO pins are capable of 15 mA source, 9 mA sinkLow-current IO pins capable of 3 mA source, 6 mA sinkCPU package has an absolute max of 130mAThe 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 DueThe Due does not have any EEPROMDue has lower power, computing faster and flash, sram bigger than mega2560Package included:1 x Ramps-FD Control Board
