The Alligator Board is designed to be a complete and reliable solution as RepRap 3D printer electronic control board. The base module features everything you need to build a standard 3D printer, and with the expansion piggy this is the most complete solution for complex 3D printer.
It is based on the 32 bit Cortex M3 ATSAM3X8EA-AU microcontroller (Arduino-Due-Compatible). This represents a big step towards greater computing power, compared to the existing solution based on 8 bit mcu. This product is well suited for any kind of 3D printer, and is the ideal solution for Delta models, requiring more complex computation.
