Reprap 3D Printer Controller Mainboard by Geeetech® – RAMPS-FD for Due

Product Name: Product ID –>

Feature: The Due, a microcontroller board based on the SAM3X8E ARM Cortex-M3, operates at 3.3V. Applying 5V to the Due’s inputs may damage the chip as it incompatible with RAMPS1.4. As a solution, we’ve created a new compatible RAMPS variant for due replacement, the RAMPS-FD.

Benefits of the RAMPS-FD over the RAMPS1.4:

• The RAMPS-FD has additional hardware protection through the jumper cap control motor drive IC.
• The RAMPS-FD boasts of more than 2-way PWM as compared to Ramps1.4.
• The RAMPS-FD has larger driving power than Ramps1.4.
• The RAMPS-FD power offers two choices:12V and 24V.

Why choose DUE over Mega?

• The CPU operates at 3.3V.
• High-current IO pins can source 15 mA and sink 9 mA.
• Low-current IO pins can source 3 mA and sink 6 mA.
• Maximum CPU package at 130mA.
• The Due has 1 dedicated SPI port and 4 multipurpose USART/SPI ports.
• The SPI port is routed to the 6 pin header used for ICSP on Mega but not on Due.
• The Due does not have any EEPROM.
• The Due has lower power, faster computing, and bigger flash and Sram than Mega2560.
  Please note: an LCD adapter for RAMPS-FD is not included and must be purchased separately.
