This is a Mega Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap 3D printer in one small package for low cost. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.

Features:

• Compatible with Cartesian or delta style 3D printers.
• Heated bed control with additional 11A fuse.
• Fits up to 5 stepper driver board.
