4x Stepper Motor Driver integrated chips are Allegro A4988 (Pololu)
Integrated USB chip FT232RL socket
Can control heatbed MK1, MK2a, MK2b, MK3
Integrated 3 MOSFET driver hot end, heatbed and fan
Integrated G code file micro SD card socket
– Fully assembled & tested, no soldering required. – It is designed to fit the entire electronics needed for a RepRap 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.
– 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
1 x 3D Printer Controller for RAMPS 1.4
Fully assembled & tested, no soldering required.
