3D Printer Kit RAMPS 1.4 REPRAP Controller Mega2560 A4988 Drivers Heatsink

Feature:

RAMPS 1.4

RAMPS designed to fit the entire electronics needed for a RepRap.
RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion.
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.
