Description

RepRap Arduino Mega Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. It is based on the powerful Freaduino 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. Additionally as long as the main RAMPS board is kept to the top of the stack a number of Arduino expansion boards can be added to the system.



Features

  • It has provisions for the cartesian robot and extruder.
  • Expandable to control other accessories.
  • 3 mosfets for heater / fan outputs and 3 thermistor circuits.
  • Fused at 5A for additional safety and component protection
  • Heated bed control with additional 11A fuse
  • Fits 5 Pololu stepper driver board
  • Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.
  • I2C and SPI pins left available for future expansion.
  • All the Mosfets are hooked into PWM pins for versatility.
  • Servo style connectors are used to connect to the endstops, motors, and leds. These connectors are gold plated, rated for 3A, very compact, and globally available.
  • SD Card add on available -- Available now made by Kliment - Sdramps
  • LEDs indicate when heater outputs on
  • Option to connect 2 motors to Z for Prusa Mendel

Version 1.4 uses surface mount capacitors and resistors to further cover edge issue cases. As of version 1.3 in order to fit more stuff RAMPS is no longer designed for easy circuit home etching. If you want to etch your own PCB either get version 1.25 or Generation_7_Electronics. Version 1.25 and earlier are "1.5 layer" designed boards (i.e. it's double sided board, but one of layers can easily be replaced with wire-jumpers) that is printable on your RepRap with the etch resist pen method, or home fabbed with toner transfer. This board is mostly based on Adrian's Pololu_Electronics and work by Tonok. Copper etch resists methods suggested by Vik. Also inspired by Vik's work with EasyDrivers. circuit design based mostly on Adrian's Pololu_Electronics Joaz at RepRapSource.com supplied initial pin definitions and many design improvements. Much inspiration, suggestions, and ideas from Prusajr, Kliment, Maxbots, Rick, and many others in the RepRap community.
