Product Description:

3D Printer Kits Controller RAMPS 1.4 + Mega 2560 R3 + 5pcs A4988 Stepper Motor Driver + LCD 12864 Graphic Smart Display

Features:
1.3D Printer Controller RAMPS 1.4
The RAMPS 1.4 board is 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.

2.Arduino-Compatible Mega 2560 R3
Fully compatible with original Arduino MEGA 2560 R3, with this product, you are able to use all the Arduino open source platform to create or learn interactive objects, it will be a lot of fun while you are creating and learning it, so just get this and start it, we also provide reference pdf files that can help you to improve skills very quickly. after all, time matters, the sooner you can improve your programing skills, the sooner you can create amazing projects!
Compared with UNO R3, this is with main Chip ATmega2560, with more I/O Pins, and additional 10 PWM output, of course, the EEPROM is also with larger space.

3.A4988 StepStick Compatible Stepper Motor Driver Module
A4988 driver is a carrier board or breakout board for Allegro's A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

4.RAMPS LCD12864 controller
This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the "smart adapter" included. After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.
