RAMPS 1.4 Arduino Mega Pololu Shield For 3D Printer - (AD23400)

Description:

RAMPS is an abbreviation for RepRap Arduino Mega Pololu Shield. It is designed to integrate all the necessary electronics for a RepRap in a compact and inexpensive package. RAMPS connects an Arduino Mega with its powerful platform and offers ample room for expansion. Its modular design includes plug-in stepper motor drivers and extruder control electronics on an Arduino MEGA shield for easy maintenance, part replacement, upgrades, and expansion. In addition, several Arduino expansion boards can be added to the system, as long as the main RAMPS board is kept at the top of the stack.

It is designed to integrate all the necessary electronics for a RepRap into a compact and inexpensive package. RAMPS connects an Arduino Mega/SainSmart Mega with its powerful platform and offers ample room for expansion.

In addition, several Arduino expansion boards can be added to the system, provided that the main RAMPS board is kept at the top of the stack.

Features:

Version 1.4 uses surface mount capacitors and resistors to better cover edge case issues. As of version 1.3, in order to integrate more components, RAMPS is no longer designed for home etching of circuits. If you want to etch your own PCB, you can purchase version 1.25 or Generation_7_Electronics. Version 1.25 and earlier are boards designed for "1.5 layers" (i.e., double-sided boards, but one of the layers can be easily replaced with wire jumpers) that can be printed on your RepRap with the etch-resist pen method, or home-made with toner transfer.

This board is mainly based on Adrian's Pololu_Electronics and Tonok's work. Vik suggested copper etch-resist methods. It is also inspired by Vik's work with EasyDrivers. The circuit design is mainly based on Adrian's Pololu_Electronics. Joaz at RepRapSource.com provided initial pin definitions and many design improvements. Much inspiration, suggestions and ideas from Prusajr, Kliment, Maxbots, Rick and many others in the RepRap community.

NOTE: This board does NOT include the drivers.
