SKU: UMRAMPS
$10.00

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.

This board now features both through-hole & surface-mount (SMT) electronic components.  You can also choose to have just the SMT components pre-soldered to your RAMPS PCB for an additional charge.  Assembly instructions and sources at RepRap.org/wiki/RAMPS1.4.  You will need a soldering iron, solder/solder paste, solder wick, flux pen, tweezers, side cutters, and basic soldering skills.  A multimeter is useful too.   This board is Open Source Hardware licensed GPLv3, so please use, copy, improve, hack, upgrade, and / or contribute.

RAMPS provisions:

  • PCB Dimensions: 102mm x 60mm
  • 3 PWM controlled mosfet powered outputs
  • Heated bed control with 11A fuse
  • 3 thermistor circuits
  • 5 Pololu Stepper Driver sockets (driver boards purchased seperately)
  • 6 sets of Digital Pins in headers with VCC and GND for endstops (endstops not included)
  • 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 (not included) and Pololu Stepper Drivers (not included) easily removable for reuse at RAMPS end of life
