Product Overview
3D Printer Kit RAMPS + LCD Controller + MEGA 2560 R3 + A4988 Driver + Endstop
Detail
The board is a microcontroller board based on the ATmega2560-16AU .It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

2. Mega Pololu Shield Compatible (RAMPS 1.4 Shield)
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.
3.LCD 2004 with Controller
This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 2004LCD 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.
4. A4988 driver module
Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered isasking for trouble.)
* Maximum output current is 2A
* Simple step and direction control interface
* Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
* Adjustable current control lets you set the maximum current output with a potentiometer,which lets you use voltages above your stepper motor’s rated voltage toachieve higher step rates
* Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
* Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
* Short-to-ground and shorted-load protection
6. SD Ramps
Breakout board for the microSD socket that is not much bigger than your fingernail. Compatible with the SPI interface found on any SD card, this tiny form factor was created for cell phone storage and is perfect for your next 3D printer project! Board comes fully assembled and tested.The bare socket is available.
