RAMPS - DIY Assembly Kit

$ 45.00

RAMPS - RepRap Arduino Mega Pololu Shield board. This is version 1.4 of our shield, designed to drive a 3D printer 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.

This DIY kit is great if you want to solder your board, and/or save money. There are several options to choose from. The default options are most popular. We recommend that beginner solderers select "UltiMachine Solders SMT" from the PCB Assembly Options.

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 complete kit)
  • 6 sets of Digital Pins in headers with VCC and GND for endstops (endstops included in complete 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 and Pololu Stepper Drivers easily removable for reuse at RAMPS end of life



PCB Assembly Options:
You Solder SMT - receive a blank PCB, unpopulated
UltiMachine solders SMT - receive PCB populated with all SMT components
