3D Printer Motherboard Reprap RAMPS-FD Shield Ramps 1.4 Control Board Compatible for Arduino Due 3D Printer Controller

Description

Features:
CPU operates at 3.3V, has an absolute max of 130mA.
High-current IO pins are capable of 15mA source, 9mA sink; Low-current IO pins capable of 3mA source, 6mA sink.
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.
12V and 24V power for option. Computing faster and flash, sram bigger than mega2560. Larger driving power than Ramps 1.4.
The Due does not have any EEPROM.
