***PLEASE NOTE***  Optical Endstop Kits are currently on backorder.  If you place an order for this kit with Optical Endstops, your entire order will wait to ship until they arrive back in stock, approx. 1 week lead time.

This is RAMPS 1.4 completely pre-assembled where you will receive all electronic components securely soldered to the PCB, tested & ready for use, one (x1) Arduino Mega 2560 connected to RAMPS, four (x4) Pololu Stepper Drivers w/ heatsinks connected to RAMPS, your choice of mechanical or optical endstop switches & wires, one (x1) USB cable.

RAMPS - RepRap Arduino Mega Pololu Shield board. This is version 1.4 of our shield, designed to drive a RepRap from an Arduino Mega.  It uses Pololu Stepper Drivers delivering up to 1/16 microstepping.  Four drivers are needed to move most 3D printers, with 3 going to the axis & one driving the extruder.  An optional fifth stepper driver socket has been provided for additional applications.

Additional information and sources at RepRap.org/wiki/RAMPS.   This board is Open Source Hardware licensed GPLv3, so please use, copy, improve, hack, upgrade, and / or contribute.

RAMPS provisions:

• 3 PWM controlled mosfet powered outputs
• Heated bed control with 11A fuse
• 3 thermistor circuits
• 5 Pololu Stepper Driver sockets (x4 drivers included with this complete kit)
• 6 sets of Digital Pins in headers with VCC and GND for endstops (mechanical endstops included with this kit)
• Uses pluggable screw terminal block for power connection
• Fused at 5A for additional safety and component protection
• Extra pins broke out :  PWM, digital, serial, SPI, I2C and analog
• Use of widely available, low cost, high quality RC servo connectors for interconnects
• Arduino MEGA (included) and Pololu Stepper Drivers (x4 included) easily removable for reuse at RAMPS end of life
