1. RAMPS 1.4

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

2. SD RAMPS Reader module

This RAMPS add-on enables you to print from MicroSD.With RAMPS 1.3 and higher it's easily connected to the RAMPS board.You will be able to print without being connected to your PC. SPI mode, Support voltage:4.5 to 5.5V,Up to 50 MB/sec data transfer rate,Sits directly on a RAMPS, Also be used with other microcontrollers.
