Introduction:When you use FOR Arduino Due as the controller of your 3D Printer, you may find the RAMPS1.4 is not compatible with DUE. As you know the FOR 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 RAMPS variant which is compatible with the Due to replace Ramps1.4.Why choose FOR Arduino DUE instead of FOR 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 BoardOur own quality management team will ensure the high quality of our products, we hope to receive your valuable suggestions for our products and make your ideas come true.
